Consider the following approximation algorithm for an optimal vertex cover. I

Consider the following approximation algorithm for an optimal vertex cover. I call it Greedy Vertex Cover 2 (GVC2): GVC2: Let G = (VE) be a graph, where V_c is the set of vertices in the vertex cover, and E_c is the set of covered edges. While (|E_cl
