The VERTEX COVER problem asks, for input consisting of a graph G on n vertices, and a positive integer k, whether there is a set of k vertices such that every edge of G is incident with at least one of these vertices. We give an algorithm for this problem that runs in time O(kn + (1.324718)'k'). In

The constraint bipartite vertex cover problem (CBVC for short) is as follows: given a bipartite graph G with n vertices and two positive integers k 1 k 2 , is there a vertex cover taking at most k 1 vertices from one and at most k 2 vertices from the other vertex set of G? CBVC is NP-complete. It fo
