Conflict graph is a union of finite given sets of disjoint completemultipartite graphs. Vertex cover on this kind of graph is used first to model data inconsistency problems in database application. It is NP-complete if the number of given sets r is fixed, and can be approximated within 2 − 1 2r (Miao et al. in Proceedings of the 9th international… CONTINUE READING
