Euler Tours) returns an Euler tour for a connected graph in Theorem 3.4, and that Algorithm 6.9 (the Jan´ıl-Prim Algorithm of Section 6.2.The idea behind Fleury’s algorithm can be paraphrased by that old piece of folk wisdom: Don’t burn your bridges behind you. Fleury’s Algorithm In graph theory the word bridge has a very specific meaning–it is the only edge connecting two separate sections (call them Fleury’s Algorithm A and B) of a graph, as illustrated in Fig. 5-18. Fleury’s algorithm is used to find a Euler Path or a Euler Circuit in a connected graph.
