Jan 8, 2018 · This algorithm is used to find euler circuit for a given graph having each vertex even Fleury's Algorithm. Start at any vertex if finding an Euler circuit. If finding an Euler path, start at one of the two vertices with odd degree. Choose any edge leaving your current vertex, provided deleting that edge will not separate the graph into two disconnected sets of edges. Add that edge to your circuit, and delete it from the graph.Suppose that we started the algoritm in some vertex u u and came to some other vertex v v. If v ≠ u v ≠ u , then the subgraph H H that remains after removing the edges is connected and there are only two vertices of odd degree in it, namely v v and u u.
