Eulerian Circuit is an Eulerian Path that starts and ends on the same vertex. How to find whether a given graph is Eulerian or not? The problem is same as following question.First you find a path between the two vertices with odd degree. Then as long as you have a vertex on the path with unused edges, follow unused edges from that vertex until you get back to that vertex again, and then merge in the new path. If there are no vertices with odd degree then you can just start with an empty path at any vertex.Eulerian Circuit is an Eulerian Path which starts and ends on the same vertex. A graph is said to be eulerian if it has a eulerian cycle. We have discussed eulerian circuit for an undirected graph. In this post, the same is discussed for a directed graph. For example, the following graph has eulerian cycle as {1, 0, 3, 4, 0, 2, 1}4. Path – It is a trail in which neither vertices nor edges are repeated i.e. if we traverse a graph such that we do not repeat a vertex and nor we repeat an edge. As path is also a trail, thus it is also an open walk. Another definition for path is a walk with no repeated vertex.With that definition, a graph with an Euler circuit can’t have an Euler path.
