Abstract: Oil palm production is of economical importance in several southern countries. The increasing demand of oil palm put a lot of pressure in several places where the rain forest and thus the tropical diversity are in danger due to deforestation. With the land already cultivated, we need to improve the yields, which means to increase the production of fruits in plots. One way is to increase the pollination or the fruit set through pollination. Palm tree has a specific entomophilous pollinator, a weevil, Elaeidobius spp, that absolutely needs male inflorescence to complete its life cycle. In young plots (3‐7 years old), mainly female inflorescences are produced, and thus, the pollinator population cannot maintain, resulting in a bad fruit set, and, thus, a bad production. That is why several questions arise: What is the mean number of male inflorescences (per hectare) needed to maintain the pollinators population above a certain threshold? And, in terms of yield, what is the optimal size of the population to reach an optimal fruit set? We propose, compare and discuss 2 different modeling approaches to develop preliminary models to study the dynamics of the pollinator population, and obtain some rough estimates of the fruit set. We derive some simulations and discuss these preliminary results.

Abstract: Murmuration, i.e. starlings gathering and swirling with extraordinary spatial coherence, is one of the most impressive kind of bird flocking. It is now well accepted that this collective behavior emerges from individual ones and that no global control is involved. In other words, every starling has an equivalent status in the flock and there is no leader deciding how the murmuration evolves. Considering this phenomenon, Reynolds’ individual-based rules have been investigated and implemented a number of times to create compelling computer-animated models of the aerial movement of swarm-like flocks of starlings. Reynolds’ model is considered as a classic Agent Based Model (ABM) and integrated as a flagship example in many ABM platforms. Still, it turns out that implementing Reynolds’ model is not sufficient per se in the sense that all murmuration simulations use tricks to achieve a convincing animation of this phenomenon. Especially, virtual leaders or points of interest are used to orientate the starlings, which somehow contradicts the no-global-control perspective, and thus suggests that murmuration dynamics is not yet fully grasped. This paper first highlight this aspect of existing murmuration simulations and then show that it is possible to obtain murmuration-like dynamics by only rethinking how Reynolds’ are usually implemented. Especially, the proposed model does not require the existence of a virtual leader nor embed any global aspect. The objective of this article is to show that it is possible to obtain complex coordinated flight dynamics using a very simple ABM and without adding external stimulus nor additional features, that is by only implementing Reynolds’s rules thanks to the IRM4S modeling perspective (an Influence Reaction Model for Simulation). So, in this article, we will first focus on the existing implementations of flocking model to list the advantages and limits and then propose our solution based on the IRM4S approach.

Hermellin, E. and Michel, F.	Defining a Methodology Based on GPU Delegation for Developing MABS Using GPGPU [Abstract]	2017	Multi-Agent Based Simulation XVII, pp. 24-41	inproceedings
Abstract: Multi-Agent Based Simulation (MABS) is used to study complex systems in many research domains. As the number of modeled agents is constantly growing, using General-Purpose Computing on Graphics Units (GPGPU) appears to be very promising as it allows to use the massively parallel architecture of the GPU (Graphics Processing Unit) to do High Performance Computing (HPC). However, this technology relies on a highly specialized architecture, implying a very specific programming approach. So, to benefit from GPU power, a MABS model need to be adapted to the GPU programming paradigm.

Abstract: Using Multi-Agent Based Simulation (MABS), computing resources requirements often limit the extent to which a model could be experimented. As the number of agents and the size of the environment are constantly growing in these simulations, using General-Purpose Computing on Graphics Units (GPGPU) appears to be very promising as it allows to use the massively parallel architecture of the GPU (Graphics Processing Unit) to do High Performance Computing (HPC). Considering the use of GPGPU for developing MABS, the conclusions of Perumalla and Aaby's work Perumalla2008 in 2008 was twofold: (1) data parallel execution capabilities of GPU can be used effectively in MABS and afford excellent speedup on models and (2) effective use of data parallel execution requires resolution of modeling and execution challenges at the cost of a decrease in modularity, ease of programmability and reusability. In this paper, we propose to study through experiments if the conclusions and issues outlined by Perumalla and Aaby are still true despite the evolution of GPGPU and MABS. To this end, we use the GPU environmental delegation principle on four models in order to compare CPU and GPU implementations. Then, we discuss and analyze the results from both a conceptual and a performance point of view.

Abstract: L’utilisation du GPGPU (General-Purpose computing on Graphics Processing Units) dans le cadre de la simulation multi-agent permet de lever, en partie, les contraintes liées au passage à l’échelle. Cependant, à cause de l’architecture massivement parallèle des GPU (Graphics Pro cessing Units) sur laquelle repose le GPGPU, les modèles voulant bénéficier des avantages de cette technologie doivent être adaptés au préalable. Prenant le parti de ne pas suivre le courant actuel qui vise à rendre transparent l’utilisation du GPGPU dans le but de simplifier son usage, le principe de délégation GPU propose plutôt de transformer un modèle afin qu’il bénéficie des avantages du GPGPU mais sans cacher la technologie utilisée. Dans cet article, nous présentons une méthodologie basée sur la délégation GPU pour le développement de simulations multi-agents. L’idée est de proposer une généralisation du processus d’application du principe de délégation GPU que nous expérimenterons ensuite sur deux cas d’études afin de définir quels sont les avantages et limites d’une telle approche.

Hermellin, E. and Michel, F.	GPU Environmental Delegation of Agent Perceptions: Application to Reynolds's Boids [Abstract] [URL]	2016	Vol. 9568Multi-Agent Based Simulation XVI, pp. 71-86	incollection
Abstract: Using Multi-Agent Based Simulation (MABS), computing resources requirements often limit the extent to which a model could be experimented with. Regarding this issue, some research works propose to use the General-Purpose Computing on Graphics Processing Units (GPGPU) technology. GPGPU allows to use the massively parallel architectures of graphic cards to perform general-purpose computing with huge speedups. Still, GPGPU requires the underlying program to be compliant with the specific architecture of GPU devices, which is very constraining. Especially, it turns out that doing MABS using GPGPU is very challenging because converting Agent Based Models (ABM) accordingly is a very difficult task. In this context, the GPU Environmental Delegation of Agent Perceptions principle has been proposed to ease the use of GPGPU for MABS. This principle consists in making a clear separation between the agent behaviors, managed by the CPU, and environmental dynamics, handled by the GPU. For now, this principle has shown good results, but only on one single case study. In this paper, we further trial this principle by testing its feasibility and genericness on a classic ABM, namely Reynolds's boids. To this end, we first review existing boids implementations and propose our own benchmark model. The paper then shows that applying GPU delegation not only speeds up boids simulations but also produces an ABM which is easy to understand, thanks to a clear separation of concerns.

Abstract: L’utilisation du GPGPU (General-Purpose Computing on Graphics Processing Units) pour la simulation multiagent permet d’améliorer les performances des modèles et lève ainsi une partie des contraintes liées au passage à l’échelle. Cependant, adapter un modèle pour qu’il utilise le GPU est une tâche complexe car le GPGPU repose sur une programmation extrêmement spécifique et contraignante. C’est dans ce contexte que la délégation GPU des perceptions agents a été proposée. L’idée derrière ce principe est d’identifier dans le modèle des calculs qui peuvent être transformés en dynamiques environnementales afin d’être calculés par des modules GPU. Il a été appliqué sur un cas d’étude et a montré de bons résultats en termes de performances et de conception. Dans cet article, nous proposons de mettre à l’épreuve la faisabilité et la généricité de cette approche en appliquant le principe de délégation GPU sur un modèle agent classique : les boids de Reynolds. Nous montrons que le principe de délégation offre des résultats intéressants au niveau des performances mais aussi d’un point de vue conceptuel (généricité, accessibilité, etc.).

Abstract: General-Purpose Computing on Graphics Units (GPGPU) is today recognized as a practical and efficient way of accelerating software procedures that require a lot of computing resources. However, using this technology in the context of Multi-Agent Based Simulation (MABS) appears to be very difficult because GPGPU relies on a very specific programming approach for which MABS models are not naturally adapted. Considering a software engineering perspective, this paper discusses the practical lessons learned from several works we have done about adapting and developing different MABS models using GPU programming. Especially, studying how GPGPU could be used in the scope of MABS, our main motivation is not only to speed up MABS but also to provide the MABS community with a general approach to GPU programming, which could be used on a wide variety of agent-based models. So, this paper first summarizes all the use cases that we have considered so far and then focuses on identifying which parts of the adaptation work could be generalized from a software engineering point of view.

Abstract: Cet ouvrage contient l’ensemble des contributions sélectionnées et présentées lors de la vingt-quatrième édition des Journées Francophones sur les Systèmes Multi-Agents (JFSMA) qui s’est tenue à Saint-Martin-du-Vivier, à proximité de Rouen (FR) du 5 au 7 octobre 2016. Par essence pluridisciplinaire, le paradigme multi-agent fournit un cadre conceptuel pour l’étude et la conception de systèmes dont la dynamique globale est le fruit d’entités autonomes – agents – qui interagissent dans un environnement commun. Les JFSMA constituent de fait un moment privilégié d’échanges scientifiques transversaux qui réunit chaque année des chercheurs qui étudient, utilisent et font évoluer le paradigme multi-agent pour adresser des problématiques issues de domaines liés à l’informatique (intelligence et vie artificielle, génie logiciel, robotique collective, etc.) et aux sciences humaines et naturelles (économie, sociologie, éthologie, etc.). Les travaux de recherche recensés dans ces actes proposent ainsi des modèles, des méthodologies, des techniques et des outils qui permettent notamment de répondre à différents problèmes que l’on peut décliner selon quatre aspects : - le développement de systèmes informatiques décentralisés où l’approche SMA permet l’intégration flexible et la coopération de logiciels et de services autonomes. - la résolution collective de problème pour laquelle il s’agit de résoudre de manière distribuée un problème qui se pose globalement à la collectivité d’agents. - la simulation de phénomènes complexes où la modélisation multi-agent apporte un cadre conceptuel permettant la représentation et la simulation de systèmes faisant intervenir différentes entités en interaction. - le développement de systèmes médiatisés où utilisateurs humains et agents artificiels interagissent directement ou indirectement, dans le cadre d’activités collectives de type éducatif, culturel ou social. Par tradition, chaque édition des JFSMA met en exergue une thématique spécifique que les auteurs sont invités à prendre en compte dans leurs contributions. Pour cette édition, le thème des journées fut «systèmes multi-agents et simulation».

Dans cet article, nous proposons de tester la généricité de cette approche en appliquant le principe de délégation GPU sur un modèle agent très classique : les boids de Reynolds. Nous montrons que le principe de délégation offre des résultats intéressants au niveau des performances mais aussi d’un point de vue conceptuel.

Agent Environments for Multi-agent Systems – A Research Roadmap [Abstract] [URL]	2015	Vol. 9068Agent Environments for Multi-Agent Systems IV, pp. 3-21	incollection
Abstract: Ten years ago, researchers in multi-agent systems became more and more aware that agent systems consist of more than only agents. The series of workshops on Environments for Multi-Agent Systems (E4MAS 2004-2006) emerged from this awareness. One of the primary outcomes of this endeavor was a principled understanding that the agent environment should be considered as a primary design abstraction, equally important as the agents. A special issue in JAAMAS 2007 contributed a set of influential papers that define the role of agent environments, describe their engineering, and outline challenges in the field that have been the drivers for numerous follow up research efforts. The goal of this paper is to wrap up what has been achieved in the past 10 years and identify challenges for future research on agent environments. Instead of taking a broad perspective, we focus on three particularly relevant topics of modern software intensive systems: large scale, openness, and humans in the loop. For each topic, we reflect on the challenges outlined 10 years ago, present an example application that highlights the current trends, and from that outline challenges for the future. We conclude with a roadmap on how the different challenges could be tackled.

Michel, F.	Approches environnement-centrées pour la simulation de systèmes multi-agents. Pour un déplacement de la complexité des agents vers l'environnement [Abstract]	2015	School: Université de Montpellier	phdthesis
Abstract: Les travaux de recherche synthétisés dans ce mémoire s’inscrivent principalement dans le domaine de la modélisation et de la simulation de systèmes multi-agents (SMA). La simulation multi-agents met en œuvre des modèles où les individus, leur environnement et leurs interactions sont directement représentés. Dans ces modèles, chaque individu –agent autonome– possède son propre comportement et produit ses actions en fonction d’une perception locale de son environnement. Ainsi, la simulation multi-agents est utilisée pour étudier des systèmes naturels comme les colonies de fourmis, les dynamiques de foules ou le trafic urbain, mais aussi pour concevoir des systèmes artificiels, par exemple dans le cadre de la robotique collective ou le développement de logiciels basés sur de l’intelligence artificielle distribuée. Dans ce cadre, nos recherches ont porté sur des problématiques liées à la modélisation de simulations multi-agents, avec la proposition de modèles formels et conceptuels (e.g. le modèle IRM4S) et d’outils logiciels génériques (plates-formes MaDKit et TurtleKit), et sur leur utilisation dans divers domaines tels que le jeu vidéo, le traitement numérique de l’image ou la robotique collective. Contrairement aux approches centrées sur la conception des comportements individuels, dans ces travaux l’environnement des agents est considéré comme une abstraction de premier ordre. Dans ce mémoire, nous dressons tout d’abord un bilan de nos recherches en argumentant l’intérêt d’une telle démarche pour les modèles multi-agents. Nous montrons ensuite comment celle-ci nous a récemment permis de proposer une approche originale dans le cadre de l’utilisation du calcul haute performance sur carte graphique (GPGPU) pour la simulation de SMA, avant de présenter les perspectives de recherche associées à notre positionnement.

Abstract: Dans le domaine des systèmes multi-agents (SMA), la puissance des CPU représente parfois un frein qui limite fortement le cadre dans lequel un modèle peut être conçu et expérimenté. Le Calcul Haute Performance (HPC) et notamment le GPGPU (General-Purpose computing on Graphics Processing Units) est une solution avantageuse en termes de performance et de coût. Cette technologie vise à utiliser les GPU pour réaliser du calcul généraliste mais souffre cependant d'une très grande complexité d'implémentation et d'accessibilité qui ne favorise pas son adoption. Cet article propose un état de l'art des contributions traitant de l'utilisation du GPGPU dans le contexte des SMA et identifie les directions les plus prometteuses en vue d'une généralisation de cette technologie dans la communauté multi-agents.

Abstract: This paper suggests multi-agent systems (MASs) for implementing game artificial intelligence (AI) for video games. One of main hindrances against using MASs technology in video games has been the real-time con- straints for frame rendering. In order to deal with the real-time constraints, we introduce an adaptation-oriented approach for maintaining frame rate in acceptable ranges. The adaptation approach is inspired from the level of detail (LoD) technique in 3D graphics. We introduce agent organizations for defining different roles of agents in game AI. The computational requirements of agent roles have been prioritized according to their functional roles in a game. In this way, adapting computational requirements of game AI works as a means for maintaining frame rate in acceptable ranges. The proposed approach has been evaluated through a pilot experiment by using a proof of concept game. The pilot experiment shows that LoD based adaptation allows maintaining frame rate in acceptable ranges and therefore enhancing the quality of service.

Translating Agent Perception Computations into Environmental Processes in Multi-Agent-Based Simulations: A means for Integrating Graphics Processing Unit Programming within Usual Agent-Based Simulation Platforms [Abstract]	2013	Systems Research and Behavioral Science, Special Issue: Conceptual Models Of Complex Systems Vol. 30(6), pp. 703-715	article
Abstract: Multi-agent-based simulations (MABS) relies on modelling the behavior of individual entities and their interactions in a virtual environment. Nowadays, MABS are used for studying various complex systems such as crowds, animal societies, ecosystems, traffic behaviors or the Market. So MABS are experimental research tools that contribute to our understanding of the mechanisms embedded in these complex systems. Still, studying some complex systems may require to consider millions of individuals. In such a case, the computing resources, which are required, represent a major obstacle for MABS end-users. In this respect, general-purpose computing on graphics processing units (GPGPU) is a relevant approach for addressing performance and scalability issues. However, GPU programming requires expert skills, which strongly limits both the accessibility and the re-usability of the frameworks developed using GPGPU. This paper presents MABS design guideline, dedicated to the GPU context, which allows the use of the GPU power without sacrificing the accessibility of MABS frameworks.

Abstract: Considering the digital simulation of complex systems, General-Purpose Computing on Graphics Processing Units (GPGPU) is a relevant approach for addressing scalability issues. However, GPU programming is a very specific approach that strongly limits both the accessibility and the re-usability of the frameworks developed using GPGPU. This paper presents our approach for the integration of GPU modules in a Multi-Agent Based Simulation (MABS) platform. Especially, this paper shows how we keep the programming accessibility of the platform while gaining advantages of the GPU power. The paper also presents how this approach could be generalized and proposes a MABS design guideline dedicated to the GPU context.

Abstract: This paper presents the work done during the first year of the EPIS project. This project deals with the process of conductingmultiple and parallelmulti agents-based simulations (MABS) on a cluster or a grid in order to generate sufficient data for scientific use ( e.g. in the case of a sensibility analysis of a simulation). We provide a new, general and user-friendly approach to marry MABS and High- Performance Computing (HPC). We, thus, propose a workflow and an associated HPC infrastructure. These two permit to easily deploy a lot of simulations on a cluster without any prior parallelizing work. The method wants to be as generic as possible: no particular MABS targeted, no overhead and HPC compliance work has to be done only once. Moreover the user is guided by a web interface that handles the workflow.

Abstract: Because Autonomous Underwater Vehicles (AUVs) have limited perception and communication capabilities, designing efficient AUV flotillas is challenging. Existing solutions are often strongly related to (1) a specific kind of mission and (2) the nature of the considered AUVs. So, it is difficult to reuse these approaches when switching to another mission context. This paper proposes a generic multi-agent based layered architecture for designing and specifying AUV flotillas at a high level of abstraction, regardless of the AUVs characteristics and skills. To this end, an organizational model is used to ease and regulate interactions between heterogeneous AUVs and combined with a behavioral reactive approach for limiting communication.

Gruau, F. and Michel, F.	Rekindling Parallelism [Abstract]	2011	Self-Adaptive and Self-Organizing Systems Workshops (SASOW), 2011 Fifth IEEE Conference on, pp. 55-60	inproceedings
Abstract: Computing in parallel means performing computation simultaneously, this generates two distinct views: (1) Performance view A mean to accelerate computation using coarse grain parallelism. (2) Decentralization view A new way of programming by decentralizing massive fine grain parallelism. Researchers on massive parallel models study the programming expressiveness, i.e. new bio-inspired ways of computing such as artificial neural network or multi agent systems solving new kinds of problems, but are usually not directly concerned about high performance. In contrast, researchers on high performance tend to narrow the scope of parallel expressiveness by preserving the sequential model of computation and defining specific language constructs that can lead to parallel run-time performance for more classical parallel algorithms. We argue that parallelism will really fully blossom only when both views get unified through the achievement of a new generic computing model that, while enabling decentralized computation, also supports classical way of programming and incorporates the hardware constraints to provide parallel performance. We are working on such a generic model called self developing self mapping network. This paper first justifies the motivation for such a model, and then sketches the fundamental principles of this model.

Abstract: This paper presents an agent-oriented visual programming approach which aims at providing MABS end-users with a means to easily elaborate artificial autonomous behaviors according to a targeted domain, namely situational programming (SP). More specifically, SP defines design principles which could be used to develop MABS visual programming toolkits suited for non developers and MABS novices. This paper presents SP and how it is used to build a MABS video game which can be played by MABS novices, that is any Internet user.

Abstract: Real-time computations in multi-agent systems have been studied from different perspectives of reasoning, message passing , resource management and negotiations. Separate treatment of all these perspectives may result in performance amelioration in one dimension while over-passing others. Here we propose an integrated “real-time” mechanism where all dimensions of temporal behavior are suggested in one unified model. Here in this position paper, we argue for an integrated and comprehensive treatment of “real-time” issue under the title of coordination. Our position regarding real-time agent coordination would result in overall performance betterment and overhead lessening, if all sub-processes are made to respect “notion of time” in design. We analyze current approaches and options as well as present an outline for an integrated and comprehensive view of “real-time coordination”.

Abstract: Cet article présente une approche pour la programmation visuelle de comportement agent. L'objectif de cette approche appelée programmation situationnelle (PS) est de permettre à des utilisateurs non informaticiens d'élaborer facilement le comportement d'entités artificielles dans le contexte d'un domaine d'application particulier. Ainsi, la PS définit un ensemble de principes de conception permettant de développer des outils de programmation visuelle susceptibles d'être utilisés par des personnes n'ayant aucune connaissance de la programmation, ni du paradigme multi-agent. Dans cet article, nous présentons la PS et la manière dont elle a été utilisée pour développer un jeu vidéo en ligne basé sur la programmation visuelle de comportements agents, et qui peut être joué par un utilisateur lambda.

Abstract: In this paper, we use multi-agent paradigm in order to propose a new method of image segmentation. The images considered in this work are the range images which can contain at once polyhedral and curved objects. The proposed method uses a multi-agent approach where agents align the region borders to the surrounding surfaces which make emerging a collective segmentation of the image. The agents move on the image and when they arrive on the pixels of a region border they align these pixels to their respective surfaces. The resulting competitive alignment allows at once the emergence of the image edges and the disappearance of the noise regions. The test results obtained with real images show a good potential of the new method for accurate image segmentation.

Michel, F., Ferber, J. and Drogoul, A.	Multi-Agent Systems and Simulation: a Survey From the Agents Community's Perspective [Abstract] [URL]	2009	Multi-Agent Systems: Simulation and Applications, pp. 3-52	incollection
Abstract: This 40 pages chapter discusses the intersection between two research fields: (1) Muti-Agent Systems (MAS) and (2) computer simulation. This intersection is considered according to two main perspectives: (1) Modeling and Simulation (M&S) for MAS and, (2) MAS for M&S. Roughly, the first case refers to projects wherein computer simulation is used as a means for designing, experimenting, studying, and/or running a MAS architecture, whatever the objectives. The second case is related to simulation experiments that use MAS as modeling paradigm to build artificial laboratories. The first part of this chapter provides the reader with an overview of some historical motivations belonging to each perspective. As this two categories both rely on simulating MAS, the second part presents and studies some basic concepts of MAS in the scope of simulation. In the third part we will argue that increasing our understanding of the intersection between MAS and simulation requires to shift our point of view from the MAS field to the simulation field. Indeed, simulation is not only a computational tool, but a real scientific discipline. As such, M&S already defines some general issues, whatever the application domain. So, the final parts of the chapter studies MAS simulation works according to a pure M&S perspective, derived from Zeigler’s framework for M&S. Doing so, our goal is twofold: (1) put in the light the relevance of studying MAS simulation according to this perspective, and (2) highlight some major challenges and issues for future research.

Abstract: Dans cet article, nous utilisons le paradigme multi-agents pour proposer une nouvelle méthode de segmentation d'images. Les images considérées dans ce travail sont les images de profondeur qui peuvent contenir à la fois des objets polyédriques et des objets courbés. La méthode proposée utilise une approche multi-agents pour l'alignement des bordures de régions afin de faire émerger une segmentation collective de l'image. Les agents se déplacent sur l'image et alignent les pixels de contours à leurs surfaces respectives. L'alignement compétitif qui en résulte permet à la fois l'émergence des contours et l'effacement des régions de bruit. Lors de leurs mouvements les agents s'auto- organisent dans l'espace de l'image via un champ de potentiel. Les résultats de test obtenus avec des images réelles montrent la pertinence de la méthode proposée pour une segmentation précise des images de profondeur.

Abstract: In this paper an agent-based segmentation approach is presented and evaluated. The approach consists in using a high number of autonomous agents for the segmentation of a range image in its different planar regions. The moving agents perform cooperative and competitive actions on the image pixels allowing a robust extraction of regions and an accurate edge detection. An artificial potential field, created around pixels of interest, allows the agents to be gathered around edges and noise regions. The results obtained with real images are compared to those of some typical methods for range image segmentation. The comparison results show the potential of the proposed approach for scene understanding in range images regarding both segmentation efficiency, and detection accuracy.

Abstract: Real environments in which agents operate are inherently dynamic: The environment changes beyond the agents' control. We advocate that, for multi-agent simulation, this dynamism must be modeled explicitly as part of the simulated environment, preferably using concepts and constructs that relate to the real world. In this paper, we describe such concepts and constructs, and we provide a formal framework to unambiguously specify their relations and meaning. We apply the formal framework to model a dynamic RoboCup Soccer environment and elaborate on how the framework poses new challenges for exploring the modeling of environments in multi-agent simulation.

Abstract: We present in this paper a multi-agent approach for range image segmentation. The approach consists in using autonomous agents for the segmentation of a range image in its different planar regions. Agents move on the image and perform local actions on the pixels, allowing robust region extraction and accurate edge detection. In order to improve the segmentation quality, a Bayesian edge regularization is applied to the resulting edges. A new Markov Random Field (MRF) model is introduced to model the edge smoothness, used as a prior in the edge regularization. The experimental results obtained with real images from the ABW database show a good potential of the proposed approach for range image analysis, regarding both segmentation efficiency, and detection accuracy.

Abstract: This paper presents and evaluates a multi-agent approach for range image segmentation. A set of reactive and autonomous agents perform a collective segmentation by partitioning a range image in its different planar regions. The agents move over the image and perform cooperative and competitive actions on the pixels, allowing a robust region extraction, and an accurate edge detection. An artificial potential field, created around the pixels of interest, ensures the agent coordination. It allows the agents to concentrate their actions around the edges and the noise regions. The experimental results show the potential of the proposed approach for scene understanding in range images, regarding both segmentation efficiency, and detection accuracy.

Abstract: Dans cet article, nous présentons un système multi-agents basé sur le champ de potentiel pour la détection de contours dans les images de profondeurs. Une populations d'agents situés est lancée afin d'explorer l'image. Lors de leur mouvement, chaque agent lisse l'image le long de son parcours, et altère les pixels qui n'appartiennent pas à la surface sur laquelle il se déplace. Sur la bordure entre deux surfaces adjacentes, deux groupes d'agents seront en compétition pour inclure les pixels de la bordure à leurs surfaces respectives. Cette compétition va préserver les contours contre l'effacement. Cependant les régions de bruits sont effacées par un lissage successif, opéré par les agents se déplaçant sur la même surface. Un champ de potentiel, crée autours des pixels altérés, permet aux agents qui sont dans le voisinage de ces pixels de se regrouper et de concentrer leur action autours de ces pixels. Après plusieurs altérations du même pixel, le champ de potentiel autour de ce pixel est relaxé, permettant aux agents qui sont sous son influence de se libérer et d'explorer d'autres régions de l'image.

Abstract: This paper describes a bio-inspired method that enables the production of artificial multiagent organisms starting from a single agent. This method relies on two complementary computing approaches: (1) mimicking the functioning of segmentation genes and homeotic genes in the development of natural embryos and (2) using techniques from the evolutionary computing and the artificial embryogeny fields. The paper first details these mechanisms and then studies some possibilities of such a bio-inspired approach developing multiagent systems that evolve and self-organize in various flag patterns.

Abstract: Several multi-agent approaches have been proposed to improve image processing. They use several image processing algorithms simultaneously. However, these approaches do not deal with the inherent problems encountered for the extraction from an image of primitive information like edges or regions. This implies that agents use macro results provided by image processing algorithms. Agents use macro results provided by image processing algorithms. Then, the results do not take advantage of all the interesting characteristics, such as environmental adaptability and emergent behavior capability, of agent-based systems: the combinative explosion of the possible solutions offered by this kind of systems, is highly reduced. In this paper, we propose a multi-agent system based on instinctual [5] reactive agents, which are able to detect edges. Agents locally perceive their environment, that is to say, pixels and additional environmental information. This environment is built using a Kirsch derivative and a Gradient Vector Flow. Edges detection emerges from agents interaction. Problems of partial or hidden contours are solved with the cooperation between the different agents. In the scope of this paper, we illustrate our approach through an example that shows how it can be used to detect lungs on 2D images coming from a scan device.

Abstract: In this paper, we propose a reactive potential-based multi-agent system for edge detection in range images. A population of situated agents is launched to explore the image. While moving, each agent smoothes the image along its path and alters points which do not belong to surface on which it moves. On the border between two adjacent surfaces, two groups of agents will be in competition to include border points into their respective surfaces. This competition will preserve contours against erasing. However, noise is erased by successive smoothing operated by agents moving on the same surface. A potential field, created around the altered points, allows the agents, moving in the neighborhood, to concentrate their actions around these points. After several alterations of the same point, the potential field around it is relaxed, allowing, agents which were under its influence, to be released and explore other areas of the image.

Abstract: This paper presents an extension of the AGR (Agent-Group-Role) organizational model, called AGRE (AGR + Environment), which includes physical (or simply geometrical) environments. This extension is based on the concept of a space which can be seen either as a physical area or as a social group, and on a clear distinction between an agent and its mode, i.e. the way it appears and interacts into a space with other agents. A notation which encompasses both social and physical environments is given.

Abstract: It is generally accepted that the environment is an essential compound of multiagent systems (MASs). Yet the environment is typically assigned limited responsibilities, or even neglected entirely, overlooking a rich potential for the paradigm of MASs. Opportunities that environments offer, have mostly been researched in the domain of situated MASs. However, the complex principles behind the concepts and responsibilities of the environment and the interplay between agents and environment are not yet fully clarified. In this paper, we first give an overview of the state-of-the-art on environments in MASs. The survey discusses relevant research tracks on environments that have been explored so far. Each track is illustrated with a number of representative contributions by the research community. Based on this study and the results of our own research, we identify a set of core concerns for environments that can be divided in two classes: concerns related to the structure of the environment, and concerns related to the activity in the environment. To conclude, we list a number of research challenges that, in our opinion, are important for further research on environments for MAS

Abstract: The study of evolving artificial organisms to build hardware or software complex systems is a promising research track. In this paper, we describe a bio-inspired method that makes agents evolve to form multiagent organisms. This method mimics the functioning of Hox genes in the development of natural embryos and implements techniques from the evolutionary computing field. Furthermore, we study the possibilities of our approach developing multiagent systems that evolve and self-organize in various flag patterns.

Weyns, D., Parunak, H.V.D., Michel, F.	Environments for Multi-Agent Systems [Abstract]	2005	Vol. 3374, pp. 279p.	book
Abstract: The notion of the environment in MAS is still young, but the number of papers contributed to this volume suggests the potential of this concept for engineered systems, and their breadth sketches the broad framework of what a mature discipline of environments for multiagent systems might resemble. The entire life cycle of environmental engineering is represented here: conceptual models and languages for the design and specification of environments, simulation environments that admit environments as first-class objects, analysis of the role played by an explicit environment in agent coordination, and examples of full applications that exploit the power of an active environment. The introductory survey pulls these themes together to offer an integrated overview of this emerging discipline. This volume shows the wide range of exploration typical of a nascent discipline as pioneers discover the best ways to frame problems and approach solutions. It will enable other researchers to take build on this body of initial exploration, and should form the foundation for a fruitful new set of tools and methods for developing multiagent systems.

Abstract: Within the Multi-agent systems (MASs) paradigm, the concept of the environment plays a central role. In fact, the autonomous agents do only exist when they are deployed on an environment. Still, there is an implicit hypothesis in current trends of the MASs considering that the agents are related to only one environment that captures all the different aspects of the application domain. In this paper we challenge this implicit hypothesis by enabling multiple occurrences of the agent-environment relationship. This brings clarity and modularity for the design and implementation of complex MASs since each environment targets a specific aspect of the application. Thanks to the proposed characterization of the agent-environment relationship, the agents are still offered a unified view about all the environments.

Abstract: This paper presents the TurtleKit simulation platform. This platform relies on the combination of a Logo simulation model with high level programming languages. Indeed, the agent model and the environment are largely inspired by the StarLogo system but can be easily extended thanks to the use of the Java programming language.

Abstract: While multi-agent systems seem to provide a good basis for building complex software systems, this paper points out some of the drawbacks of classical “agent centered” multi-agent systems. To resolve these difficulties we claim that organization centered multi-agent system, or OCMAS for short, may be used. We propose a set of general principles from which true OCMAS may be designed. One of these principles is not to assume anything about the cognitive capabilities of agents. In order to show how OCMAS models may be designed, we propose a very concise and minimal OCMAS model called AGR, for Agent/Group/Role. We propose a set of notations and a methodological framework to help the designer to build MAS using AGR. We then show that it is possible to design multi-agent systems using only OCMAS models.

Michel, F.	Formalisme, outils et éléments méthodologiques pour la modélisation et la simulation multi-agents [Abstract]	2004	School: Université Montpellier II	phdthesis
Abstract: Cette thèse aborde des questions liées à la simulation informatique de systèmes complexes modélisés à l'aide du paradigme multi-agents. Cette approche repose sur l'idée qu'il est possible de représenter directement le comportement et les interactions d'un ensemble d'entités autonomes évoluant dans un environnement commun. Mal maîtrisée, la complexité des modèles considérés pose encore aujourd'hui de nombreux problèmes quant à leur élaboration et à leur implémentation. L'une des conséquences les plus critiques réside dans la difficulté de reproduire fidèlement les modèles publiés dans la littérature. Ce qui pose le problème de la vérification et de la validation de ce type de simulations. Dans cette thèse, nous considérons que ce problème est en majeure partie lié à un manque de correspondance entre les spécifications des modèles et les structures informatiques qui permettent de les exécuter. Le but de nos travaux est de faire un pas vers une mise en correspondance effective de ces deux parties. Pour cela, nous considérons deux approches complémentaires. La première se focalise sur l'élaboration d'outils génériques de conception de simulateurs. Il s'agit de rendre plus explicites les structures informatiques utilisées pour l'implémentation. La deuxième repose sur l'étude des moyens aujourd'hui utilisés pour modéliser un système multi-agents. Dans ce cadre, nous proposons une réflexion globale sur ce paradigme et nous identifions un ensemble de contraintes liées à son utilisation. A partir de cette réflexion, nous proposons un principe de modélisation basé sur l'approche Influence/Réaction et sur l'utilisation d'un modèle formel d'environnement pour systèmes multi-agents appelé MIC*. Nous montrons en quoi notre approche permet de respecter les différentes contraintes de modélisation identifiées et nous illustrons sa faisabilité à l'aide d'un exemple concret.

Michel, F., Gouaïch, A. and Ferber, J.	Weak Interaction and Strong Interaction in Agent Based Simulations [Abstract]	2004	Vol. 2927Multi-Agent-Based Simulation III, pp. 43-56	incollection
Abstract: This paper addresses the problem of the engineering divergence phenomenon in ABS. This problem is related to the fact that a particular conceptual model may give different outputs according to its implementation. Through two experiments, the paper shows that the implementation of the agents’ interaction is one of the factors that are involved in this phenomenon. The underlying idea of this paper is that this problem can be greatly diminished if the analysis of the conceptual model incorporates some key concepts which are crucial for the implementation. To this end, this work proposes to identify two different classes of interaction: weak interactions and strong interactions.

Abstract: Ubiquitous systems can be considered as good challenges and case studies for the reliable development of open, cooperative and mobile systems in a globally uncontrolled environment. Furthermore, the complexity of these systems could constitute a real barrier to classical engineering approaches and validate the foundations of agent based computing. In this paper, we have abstracted a composable multi-agent system environment in an algebraic structure where mobile, interacting and autonomous entities evolve. We present also, a simple ubiquitous application developed according to the abstract model principles.

Abstract: Les systèmes ubiquistes sont de bons défis lancés aux communautés de l'ingénierie des systèmes informatiques pour le développement fiable de systèmes ouverts, mobiles et coopératifs. L'interaction se trouve au centre de ces systèmes. En effet, le schéma d'interaction entre les composants est très variable et dépend des propriétés environnementales. Pour pouvoir comprendre ces environnements et leurs propriétés, il est donc indispensable de les décrire d'une façon globale et rigoureuse. Ce papier présente un modèle algébrique de tels environnements où des entités mobiles, interactionnelles et autonomes évoluent. Les évolution de cette structure sont caractérisées pour définir les concepts de mouvement, d'interaction et de computation. Nous illustrerons également comment ce modèle est utilisé concrètement pour développer une application ubiquiste.

Abstract: This paper presents the MIC algebraic structure modelling an en- vironment, called the deployment environment, where autonomous, interacting and mobile entities evolve. The underlying idea of this work is that the system coherency rules assumptions are guaran- teed by the structure of the deployment environment itself and no assumption is made on of the internal behaviours of agents. Thus, every agent has to follow the rules of the deployment environment to being able to interact with others. So, any misuse will be trans- parently rejected by the structure and other agents are not affected by bogus actions.

Abstract: In this paper, we present MadKit/SEdit, an agent infrastructure combined with a generic design tool for multi-agent systems. This toolkit is based on a organizational metaphor to integrate highly heterogeneous agent systems. We explain the principles of MadKit, the underlying agent platform, and show how it can integrate various agent architectures and provides structuration for multiple simultaneous systems and semantics. The architecture, based on a minimal agent runtime, agentified platform services and modular application host, is presented. The SEdit design tool, built itself as a MAS is also discussed. We present its key points in terms of multi-model support, and integration with the infrastructure, from design to maintenance. We illustrate our approach by discussing some consequences of this architecture, and describe our motivation for this design: integration and reuse, organizational patterns, and overall versatility. A summary is given of some key MadKit-based applications to date.

Abstract: Cet article présente une méthodologie originale pour la conception de simulateur multi-agents basée sur le modèle organisationnel AALAADIN. Cette approche vise notamment à faciliter l’étude des problèmes liés à la gestion de l’exécution des agents (le problème du scheduling). L’idée principale est d’envisager le simulateur comme un système multi-agents (SMA) de façon à exploiter sa structure organisationnelle sous-jacente pour expliciter ce problème. Dans l’optique de cette méthodologie, nous proposons des outils de simulation qui sont génériques dans le sens où ils n’imposent aucune contrainte sur la politique d’exécution envisagée. Au contraire, leur but est de permettre l’élaboration de structures d’activation complexes qui restent compréhensibles, modifiables et donc analysables grâce à une décomposition logique du problème. Plus précisément, nous décrivons ici le fonctionnement d’un agent de la plate-forme MADKIT nommé Scheduler qui permet l’élaboration de telles politiques d’exécution.

Abstract: This paper presents generic simulation tools which rely on an original methodological approach of designing multi-agent simulators. We will see that these tools are generic specially because they are not related to a particular scheduling method. On the contrary they aim at providing facilities that allow to design complex activation structures that remain comprehensible, analyzable and moreover modifiable, thanks to a problem division. To achieve this, the main idea of this methodology is to express the multi-agent system (MAS) simulator as a particular MAS itself and use explicitly its subjacent organizational structure. We will show how the sc Aalaadin organizational model enables us to finely apply such a methodology. Precisely, we will present a particular agent of sc MadKit (the platform that relies on sc Aalaadin): the Scheduler agent and its tool called Activator.

Abstract: Dans cet article, nous présentons l’architecture de MadKit (pour “Multi-Agent Development Kit”), une plate-forme générique de conception et d’exécution de systèmes multi-agents. Cette plate-forme a l’originalité d’être basé sur un modèle organisationnel plutôt qu’une architecture d’agent ou un modèle d’interaction spécifique. L’utilisation de groupes et de rôles associés à des agents est mis en oeuvre en tant qu’outil de modélisation et de conception pour les développeurs de systèmes multi-agents, mais également comme principe d’architecture de la plate-forme elle-même. Cette architecture est basée sur un noyau agent minimal découplé de tout modèle individuel d’agent. Dans cette plate-forme, les services classiques de passage de message distribués, de migration ou de surveillance sont fournis au meta-niveau par des agents spécialisés afin d’obtenir un maximum de flexibilité. Une interface graphique componentielle et découplée du noyau et des agents permet de supporter différentes modes d’utilisation et d’exploitation de la plate-forme. Nous illustrons notre propos en présentant certaines conséquences, déclinaisons et applications de cette plateforme.

Abstract: Dans cet article, nous présentons une approche méthodologique originale de la conception de simulateur multi-agents basée sur un modèle organisationnel. Ce modèle, appelé Aalaadin, permet une description simple de structures d’organisation et d’interactions dans les systèmes multi-agents (SMA). Nous montrons que l’utilisation de ce modèle permet d’envisager simplement et efficacement l’analyse du problème fondamental du scheduling dans les simulations multi-agents. Ce problème consiste à assurer que les agents d’une simulation sont soumis à une même loi temporelle et qu’ils agissent « tous en même temps ». Lié aux difficultés de modéliser la simultanéité entre agents, ce problème fondamental a très peu été étudié car difficile à expliciter. Nous décrivons ici le fonctionnement d’un agent de la plate-forme MadKit nommé scheduler qui permet de surmonter ces difficultés d’analyse et de conception. Son principe est de décomposer le problème du scheduling global en autant de sous-problèmes que nécessaire. Ainsi nous montrons comment son fonctionnement permet de construire des politiques d’exécution toujours plus raffinées qui restent compréhensibles grâce d’une part à la localisation des problèmes et, d’autre part, à l’explicitation de la structure organisationnelle du simulateur.
