QotD14 Q1 Homework. Unanswered. Due in 9 hours Consider two graphs, G1 and G2, both containing N vertices. G1 is sparse and G2 is dense. Consider a vertex v in each graph. I would like to find all of the neighbors of v using an adjacency matrix. Choose the correct answer below.

6. Prove that the following graphs are connected: (a) The 3 vertex cycle: (b) The following 4 vertex graph: (c) K 7. An edge e of a connected graph G is called a cut edge if the graph G obtained by deleting that edge (V(G) V(G) and E(G) E(G) \<ej) is not connected.

Problem 8. (2+4+4 points each) A bipartite graph G = (V. E) is a graph whose vertices can be partitioned into two (disjoint) sets V1 and V2, such that every edge joins a vertex in V1 with a vertex in V2. This means no edges are within V1 or V2 (or symbolically: Vu, v E V1. {u, u} &E and Vu, v E V2.{u,v} &E). 8(a) Show that the complete graph K, is a bipartite graph. 8(b) Prove that no...

(7) Let V = {ui, U2 . . . . Un} with n > 4. In this exercise we will compute the probability that in a random graph with vertex set V we have that v and v2 have an edge between them or have an edge to a common vertex (i.e, have a common neighbour) (If you are troubled by my use of the term random we choose a graph on n vertices uniformly at random from the set...
