This thesis deals with the integration of Constraint and Linear Programming techniques for solving combinatorial optimization problems. The target problems are the Multidimensional Zero-One Knapsack Problem and the Frequency Assignment Problem.We propose a branch and cut method for solving Integer Linear programming models. This framework is applied in the core of an hybrid Constraint Programming method associated to a relaxation solved by Linear Programming.The originality of the proposed approach is to use the reduced costs of the linear relaxation's variables for generating logic constraints to improve the constraint propagation process.For the frequency assignment problem, this method is applied to a new model based on a more realistic ...
