Résumé: This Ph.D. thesis concerns algorithms for Combinatorial Optimization Problems. In Combinatorial Optimization
Problems the set of feasible solutions is discrete or can be reduced to a discrete one, and the goal is to find the best
possible solution. Specifically, in this research we consider three different problems in the field of Combinatorial
Optimization including One-dimensional Bin Packing (and two similar problems), Machine Reassignment Problem
and Rolling Stock Problem. The first one is a classical and well known optimization problem, while the other two
are real world and very large scale problems arising in industry and have been recently proposed by Google and
French Railways (SNCF) respectively. For each problem we propose a local search based heuristic algorithm and
we compare our results with the best known results in the literature. Additionally, as an introduction to local search
methods, two metaheuristic approaches, GRASP and Tabu Search are explained through a computational study on
Set Covering Problem.
