Being a postman, you would like to know the best route to distribute your letters without visiting a street twice? This problem of finding a cycle that visits every edge of a graph only once is called the Eulerian cycle problem. It is named after the mathematician Leonhard Euler, who solved the famous Seven Bridges of Königsberg problem in 1736.

Fleury's algorithm is a simple algorithm for finding Eulerian paths or tours. It proceeds by repeatedly removing edges from the graph in such way, that the graph remains Eulerian. The steps of Fleury's algorithm is as follows: Start with any vertex of non-zero degree. Choose any edge leaving this vertex, which is not a bridge (cut edges).Fleury's algorithm is an elegant, but inefficient, method of generating an Eulerian cycle. An Eulerian cycle of a graph may be found in the Wolfram Language using FindEulerianCycle[g]. The only Platonic solid possessing an Eulerian cycle is the octahedron, which has Schläfli symbol; all other Platonic graphs have odd degree …Following is Fleury’s Algorithm for printing the Eulerian trail or cycle Make sure the graph has either 0 or 2 odd vertices. If there are 0 odd vertices, start anywhere. If there are 2 odd vertices, start at one of them. Follow edges one at a time.

Now we know how to determine if a graph has an Euler circuit, but if it does, how do we find one? While it usually is possible to find an Euler circuit just by pulling out your pencil and trying to find one, the more formal method is Fleury's algorithm. Fleury's Algorithm. Start at any vertex if finding an Euler circuit. Google Books (accessed 11/14/2022).
