7. An independent set in a graph G is a subset S C V(G) of vertices of G which are pairwise non-adjacent (i.e., such that there are no edges between any of the vertices in S). Let Q(G) denote the size of the largest independent set in G. Prove that for a graph G with n vertices, GX(G)n- a(G)+ 1.

(a) Given a graph G = (V, E) and a number k (1 ≤ k ≤ n), the CLIQUE problem asks us whether there is a set of k vertices in G that are all connected to one another. That is, each vertex in the ”clique” is connected to the other k − 1 vertices in the clique; this set of vertices is referred to as a ”k-clique.” Show that this problem is in class NP (verifiable in polynomial time)...

Consider the following weighted, directed graph G. There are 7 vertices and 10 edges. The edge list E is as follows:The Bellman-Ford algorithm makes |V|-1 = 7-1 = 6 passes through the edge list E. Each pass relaxes the edges in the order they appear in the edge list. As with Dijkstra's algorithm, we record the current best known cost D[V] to reach each vertex V from the start vertex S. Initially D[A]=0 and D[V]=+oo for all the other vertices...

7. For a graph G of order n 2, define the k-connectivity Kk(G) of G (2 S k n) as the minimum number of vertices whose removal from G results in a graph with at least k components or a graph of order less than k. (Therefore, K2(G) = K(G).) A graph G is defined to be (f,k)- connected if Kk(G) . Let G be a graph of order...
