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 can be used to derive an Euler path. Fleury's algorithm. Select some edge that is not a bridge and remove this edge from the given graph. This edge will be the first edge in the Euler circuit. Repeatedly select a non-bridge edge to be added to the Euler circuit and remove this edge from the given graph.

Theorem 5.1.3 If G is eulerian, then any circuit constructed by Fleury’s algorithm is eulerian. Proof. Let G be an eulerian graph.
