Research activities (sorry, only french text)
Combinatorial Optimization: Build innovative algorithms for optimization problems with discrete variables\\
Robust Optimization: Study optimization problem having uncertain data. We look for the solution that minimize the worst cost induced by the uncertain data. \\
See personnal website for a recent publication list.
Bilevel Optimization: Optimization problem that model Stackelberg games: we optimize the decision of the leader that have to take into account the optimal response of the follower
Optimization & Big Data: We study large LP/ILP. We use random projection to reduce significantly the number of constraints in the problem and solve large optimization problem with short amount of time
Network Optimization: Optimal sensor location in networks, smartgrods
