A vertex cover for a graph, G, is a set of vertices, C, such that every edge in G is incident to one of the vertices in C. The problem of finding a smallest vertex cover is useful in network monitoring and other applications, but it is a difficult problem for general graphs. Show that the problem of finding a smallest vertex cover in a bipartite graph can be solved in polynomial time.
