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. With that definition, a graph with an Euler circuit can't have an Euler path. Other people say that an Euler path has no restriction on start and end vertices. With that definition, a graph with an Euler circuit automatically has an Euler path (which is …Determine whether there is Euler circuit. The exercise: Asks for both of Eulerian circuit and path circuit. Conditions: 1)-Should stop at the same point that started from. 2)- Don't repeat edges. 3)-Should cross all edges. After long time of focusing I found the Eulerian path, I tried so much on the circuit but could not find it.This modified graph has only two odd vertices, so there's an Eulerian path from one of the remaining odd vertices to the other. Removing the n/2-1 dummy edges from this path results in n/2 separate paths, which go through each edge exactly once. I should (and will) add that Euler's original argument shows it must be at least n/2.Directed Graph: Euler Path.
