How to know if a graph is eulerian
WebA graph that has an Eulerian trail but not an Eulerian circuit is called Semi–Eulerian. An undirected graph is Semi–Eulerian if and only if. Exactly two vertices have odd degree, and; All of its vertices with a non-zero degree belong to a single connected component. The … WebConjecture 1.1 (Bollobas–Scott [1]). Let G be an Eulerian directed graph with average degree at least d. Then G contains a directed cycle of length at least cd for some absolute
