Webwhere an edge is defined to be an unordered pair of vertices. The order of G, denoted jGj, is the cardinality of V(G). A graph is simple if it has no multiple edges or loops. The complement of a graph G(V;E) is the graph G= (V;E), where Econsists of all those edges of the complete graph K jGjthat are not in E. A matrix A= [a WebMar 24, 2024 · For an undirected graph, an unordered pair of nodes that specify a line joining these two nodes are said to form an edge. For a directed graph, the edge is an ordered pair of nodes. The terms "arc," …
WebMore than one edge going in the same direction between vertices, however, is not allowed. A directed edge is de ned by an ordered pair rather than an unordered pair. That is, the ordered pair (a;b) is di erent from the ordered pair (b;a), while the unordered pair fa;bg= fb;ag. Be careful of the notation you use when writing an edge. Exercise 1.5.1.
