Résumé: The neighborhood dominant polytope
Description: Yue Zhang We propose a new polyhedral approach for combinatorial optimization problems. Rather than working on the convex hull of the feasible set, we focus on a polytope that excludes the uninteresting feasible solutions dominated in a local neighborhood. In this work, the idea is applied to the linear Knapsack problem and the quadratic MaxCut problem with a theoretical study that demonstrates dominance inequalities and facets. The outstanding effectiveness of the proposed inequalities is numerically shown on the MaxCut instances from the BiqBin library.
