Research

Our work is about metaheuristics and nature-inspired intelligent search methods for solving large-scale complex combinatorial problems. We are especially interested in methods based on advanced neighborhood search, evolutionary computing and hybrid/memetic computing approaches.

Metaheuristics are general methods applicable to a large number of problems. These methods are known today to be among the most powerful methods for tackling hard and large combinatorial problems.

Target applications of metaheuristics concern those highly combinatorial and strongly constrained problems which cannot be solved other ways. Typical examples of such applications include resource assignment, planning, scheduling and re-scheduling, timetabling and inventory...

Our research is carried out in several tightly related directions. We develop high performance methods for real applications including:

• community detection in complex networks
• combinatorial auctions
• frequency assignment for mobile radio networks (application of France Telecom)
• antenna positioning for mobile radio networks (European Esprit IV project)
• inferring autonomous system relationships in the Internet (France Telecom R&D)
• photograph scheduling of an earth observation satellite (application of CNES)
• integrated vehicle and driver scheduling 
• optimization of BSS architecture (application of Bouygues Telecom)
• timetabling and nurse rostering
• constrained Steiner tree problems and quadratic spanning tree problem
• sports league scheduling
• progressive party problem...

and for general NP-hard problems such as:

• graph coloring, (set) T-coloring, bandwidth coloring, sum coloring, and maximum clique
• graph partitioning, graph bisection, max-cut, vertex separator
  
• constrained Steiner tree problems, quadratic minimum spanning tree problem
• maximum diversity problem, maximally diverse grouping problem
• Quadratic optimization : unconstrained binary quadratic problem, quadratic assignment, quadratic knapsack 
• (maximal) constraint satisfaction problems (CSP and MCSP) and satisfiability (SAT and Max-SAT)
• linear arrangement, linear ordering and bandwidth minimization
• 2D strip packing
• multidimensional knapsack and multiple-choice multidimensional knapsack...

• biomakers identification and regulation networks
• gene selection, classification and biclustering of microarray data
• phylogeny reconstruction and maximum parsimony

Other research activities include multiobjective optimization, dynamic optimization and uncertain optimization by metaheuristics. Finally, we are interested in general purpose problem solvers based on metaheuristics, fundamental issues related to the design and understanding of the heuristic methods (landscapes, search space analysis, distribution of local optima...).
