1 Answer. Sorted by: 1. What you need to do is form arbitrary cycles and then connect all cycles together. You seem to be doing only one depth first traversal, which might give you a Eulerian circuit, but it also may give you a 'shortcut' of an Eulerian circuit. That is because in every vertex where the Eulerian circuit passes more then once (i ...

Solution. By the results in class, a connected graph has an Eulerian circuit if and only if the degree of each vertex is a nonzero even number. Suppose connects the vertices v and v0if we remove e we now have a graph with exactly 2 vertices with odd degrees.
