D. graph and its complement
WebJun 1, 1987 · If d + a < 4 or d- tt < 4, there must be d = 1 or a = 1, then G = Kj, (or t~ = K~,). This is contrary to assumption that both G and t~ are connected. We can find a graph for … Webwith any of the original graphs. The graph C 5 is its own complement (again see Problem 6). We now examine C n when n 6. The graph C n is 2-regular. Therefore C n is (n 3)-regular. Now, the graph N n is 0-regular and the graphs P n and C n are not regular at all. So no matches so far. The only complete graph with the same number of vertices as ...

WebGraphDifference gives the graph obtained from the union of vertex sets of two graphs and the complement of the second graph ’ s edge set with respect to the first. GraphComplement gives the graph that has the same vertex set as a given graph, but with edges corresponding to absent edges in the original (and vice versa). Webwhere e(S;S„) is the number of edges between S and its complement. Deflnition 2. A graph is a (d;†)-expander if it is d-regular and h(G) ‚ †. Observe that e(S;S„) • djSj and so † cannot be more than d. Graphs with † comparable to d are very good expanders. Expanders are very useful in computer science. We will mention some ...
