Let Q:= {1,2,...,q}. Let G be a graph with the elements of Q^n as vertices and an edge between (a1,a2,...,an) and (b1,b2,...bn) if and only if ai is not equal to bi for exactly one value of i. Show that G is Hamiltonian.
Let G -(V, E) be a graph. The complementary graph G of G has vertex set V. Two vertices are adjacent in G if and only if they are not adjacent in G. (a) For each of the following graphs, describe its complementary graph: (i) Km,.ni (i) W Are the resulting graphs connected? Justify your answers. (b) Describe the graph GUG. (c) If G is a simple graph with 15 edges and G has 13 edges, how many vertices does...
(Problem R-14.16, page 678 of the text) Let G be a graph whose vertices are the integers 1 through 8, and let the adjacent vertices of each vertex be given by the table below: Vertex adjacent vertices 1 (2,3,4) 2 (1,3,4) 3 (1,2,4) 4 (1,2,3,6) 5 (6,7,8) 6 (4,5,7) 7 (5,6,8) 8 (5,7) Assume that, in a traversal of G, the adjacent vertices...

4. Consider ?3, the graph whose vertex set is ? = {000,001,010,011,100,101,110,111} where two vertices are joined by an edge if and only if they differ in exactly one coordinate. Give a list of three internally disjoint paths that start at 000 and end at 111.
Can you explain your answer to each question so I can better understand. The odd graph, Ok, is a graph with vertices that are the k-element subsets of (1,2,...,2k+ 5. 17. Two vertices in Ok are adjacent if and only if they are disjoint sets. (a) Draw O2 (b) What is the degree of each vertex? (c) Prove that in O2 if two vertices are not adjacent to each other, then they share a common neighbor (that is, they are...
Question 1: Given an undirected connected graph so that every edge belongs to at least one simple cycle (a cycle is simple if be vertex appears more than once). Show that we can give a direction to every edge so that the graph will be strongly connected. Question 2: Given a graph G(V, E) a set I is an independent set if for every uv el, u #v, uv & E. A Matching is a collection of edges {ei} so...

Give an example of such a set Prove that a smaller set does not exist. A dominating sot is a set of vertices for which all other vertices have nt lenst ane neighbar in this set. What is the e of the smallest dominating...
4. Approximating Clique. The Maximum Clique problem is to compute a clique (i.e., a complete subgraph) of maximum size in a given undirected graph G. Let G = (V,E) be an undirected graph. For any integer k ≥ 1, define G(k) to be the undirected graph (V (k), E(k)), where V (k) is the set of all ordered k-tuples of vertices from V , and E(k) is defined so that (v1,v2,...,vk) is adjacent to (w1,w2,...,wk) if and only if, for...
