MAORE: Méthodes Algorithmes pour l'Ordonnancement et les Réseaux

The members of MAORE are using the tools of combinatorial optimization, graph theory, mathematical programming, and constraint programming to solve discrete optimization problems exactly or approximately. Our main application fields are networks and scheduling. Our analysis addresses the complexity, approximability and robustness. We are interested in the theoretical properties of the algorithms as well as in their numerical efficiency on real instances. The application studied have led collaborations with researchers of various fields (microelectronics, robotics, bio-informatics, software engineering).
