2. The greedy algorithm for the vertex cover problem picks a highest degree vertex v, includes v in the cover, deletes all edges incident to v, and repeats until there are no edges left. Show that this algorithm is not a c-approximation algorithm for any c. Hint: consider a bipartite graph G = (A, B, E) with |A| = n and B _Bi, where Bi] = [n/i]. Vertices in B; have degree i, and the neigh- borhoods of different vertices are disjoint
