This thesis aims at using machine learning techniques in the context of Mixed Integer LinearProgramming instances generated by stochastic data. Rather than solve these instances independentlyusing the Branch and Bound algorithm (B&B), we propose to leverage the similarities between instancesby learning inner strategies of this algorithm, such as node selection and branching.The main approach developed in this work is to use reinforcement learning to discover by trials-and-errorsstrategies which minimize the B&B tree size. To properly adapt to the B&B environment, we definea new kind of tree-based transitions, and elaborate on different cost models in the correspondingMarkov Decision Processes. We prove the optimality of the unitary cost mod...
