A simple graph is an undirected graph that has no loops and no more than one edge between any two vertices. If the simple graph G has v vertices and e edges how many edges does the complement G¯ have ?
Draw all nonisomorphic simple graph with five vertices and three edges?
Show that if G is a directed graph, then it is possible to remove vertices to disconnect G if and only if G is not a complete graph.
