- Description
- Let G be a graph with vertex set V(G) and edge set E(G). We consider the problem of orienting the edges of a complete bipartite graph Kn,n so only two different in-degrees a and b occur. An obvious necessary condition for orienting the edges of G so that only two in-degrees a and b occur, is that there exist positive integers s and t satisfying s+t=|V(G)| and as+bt=|V(G)|. In this paper, we show that the necessary condition is also sufficient for a complete bipartite graph Kn,n. Furthermore, we give the algorithms of orientations with only two in-degrees of Kn,n.
