This article deals with the two-stage stochastic model, which aims at explicitly taking into account uncertainty in optimization problems, that Kong and Schaefer have recently studied for the maximum weight matching problem [N. Kong, A.J. Schaefer, A factor 1/2 approximation algorithm for...

This paper is devoted to the search of Choquet-optimal solutions in finite graph problems with multiple objectives. The Choquet integral is one of the most sophisticated preference models used in decision theory for aggregating preferences on multiple objectives. We first present a condition on...

Chains of operations have to be scheduled on a single machine such that a minimum delay is set between any two operations linked by a precedence relation. Three sub-problems are shown to be solved in polynomial time. First, we consider the problem of minimizing the makespan when all the...
