dc.titleThe vertex k-cut problemen
dc.typeArticle accepté pour publication ou publié
dc.description.abstractenGiven an undirected graph G=(V, E), a vertex k-cut of G is a vertex subset of the removing of which disconnects the graph in at least components. Given a graph and an integer k≥2, the vertex k-cut problem consists in finding a vertex k-cut of of G minimum cardinality. We first prove that the problem is NP-hard for any fixed k≥3. We then present a compact formulation, and an extended formulation from which we derive a column generation and a branching scheme. Extensive computational results prove the effectiveness of the proposed methods.en
