Example of euler path and circuit.

An Eulerian path, also called an Euler chain, Euler trail, Euler walk, or "Eulerian" version of any of these variants, is a walk on the graph edges of a graph which uses each graph edge in the original graph exactly once. A connected graph has an Eulerian path iff it has at most two graph vertices of odd degree.

An Euler circuit must include all of the edges of a graph, but there is no requirement that it traverse all of the vertices.

Site: http ... If a graph has an Euler circuit, that will always be the best solution to a Chinese postman problem. Let’s determine if the multigraph of the course has an Euler circuit by looking at the degrees of the vertices in Figure 12.116. Since the degrees of the vertices are all even, and the graph is connected, the graph is Eulerian. An Eulerian circuit is an Eulerian path that starts and ends at the same vertex.
