A directed graph having no symmetric pair of directed edges ...But this proof also depends on how you have defined Complete graph. You might have a definition that states, that every pair of vertices are connected by a single unique edge, which would naturally rise a combinatoric reasoning on the number of edges.A complete graph with 14 vertices has 14(13) 2 14 ( 13) 2 edges. This is 91 edges. However, for every traversal through a vertex on a path requires an in-going and an out-going edge. Thus, with an odd degree for a vertex, the number of times you must visit a vertex is the degree of the vertex divided by 2 using ceiling division (round up).However, this is the only restriction on edges, so the number of edges in a complete multipartite graph K(r1, …,rk) K ( r 1, …, r k) is just. Hence, if you want to maximize maximize the number of edges for a given k k, you can just choose each sets such that ri = 1∀i r i = 1 ∀ i, which gives you the maximum (N2) ( N 2).Complete graph with n n vertices has m = n(n − 1)/2 m = n ( n − 1) / 2 edges and the degree of each vertex is n − 1 n − 1.
