Fleury's algorithm
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.

Fleury's Algorithm is used to display the Euler path or Euler circuit from a given graph. In this algorithm, starting from one edge, it tries to move other adjacent vertices by removing the previous vertices. Using this trick, the graph becomes simpler in each step to find the Euler path or circuit.Hierholzer’s Algorithm has its use mainly in finding an Euler Path and Eulerian Circuit in a given Directed or Un-directed Graph. Euler Path (or Euler Trail) is a path of edges that visits all the edges in a graph exactly once. Hence, an Eulerian Circuit (or Cycle) is a Euler Path which starts and ends on the same vertex.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. If you have a choice between a bridge and a non-bridge, always choose the non-bridge.FOR FLEURY’S ALGORITHM SIMULATION Gloria Sánchez–Torrubia, Carmen Torres–Blanc, Leila Navascués-Galante Abstract: EulerPathSolver is a new application, that meets eMathTeacher specifications and simulates Fleury’s algorithm execution. The application runs in a Java Web Start Window and features an animation of the algorithmIn graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex.
It can be shown that Fleury's algorithm always produces an Eulerian path, and produces an Eulerian circuit if every vertex has even degree. This uses an important and straightforward lemma known as the handshaking …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.

On a graph, an Euler's path is a path that passes through all the edges of the graph, each edge exactly once. Euler's path which is a cycle is called Euler's cycle. For an Euler's path to exists, the graph must necessarily be connected, i.e. consists of a single connected component.Final answer.
