A vertex cover of an undirected graph G = (V, E) is a subset of the vertices which touches everyedgethat is, a subset S V such that for each edge {u, v} E, one or both of u, v are in S.Show that the problem of finding the minimum vertex cover in a bipartite graph reduces to maximumflow. (Hint: Can you relate this problem to the minimum cut in an appropriate network?)
