In the previous section, we found Euler circuits using an algorithm that involved joining circuits together into one large circuit. You can also use Fleury’s algorithm to find Euler circuits in any graph with vertices of all even degree. In that case, you can start at any vertex that you would like to use. Step 1: Begin at any vertex. In this case paths and circuits can help differentiate between the graphs. Example – Are the two graphs shown below isomorphic? Solution – Both the graphs have 6 vertices, 9 edges and the degree sequence is the same. However the second graph has a circuit of length 3 and the minimum length of any circuit in the first graph is 4.
