This thesis addresses the Robust counterpart of binary linear problems with ellipsoidal uncertainty sets. Since this problem is hard, a heuristic approach, based on Frank- Wolfe’s algorithm named Discrete Frank-Wolf (DFW), has been proposed. In this approach, we are interested in the optimum of the linear approximation that the algorithm computes at each iteration when relaxing the constraint set in its convex hull. For small dimensional instances, our method is able to provide the same optimal integer solution as an exact method provided by CPLEX, after no more than a few hundred iterations. Moreover, as opposed to the exact method, DFW Algorithm applies to large scale problems as well. The numerical results are applied on the robust short...
