Fleurys algorithm.

Eulerian Circuit is an Eulerian Path which starts and ends on the same vertex. A graph is said to be eulerian if it has a eulerian cycle. We have discussed eulerian circuit for an undirected graph. In this post, the same is discussed for a directed graph. For example, the following graph has eulerian cycle as {1, 0, 3, 4, 0, 2, 1}

Here’s how Fleury’s algorithm works: First , if every vertex is even, then start anywhere, but if there are two odd vertices, pick one of them to start at. Second , from that vertex, pick an edge to traverse, but know that you can’t go back once you traverse the edge, so don’t cross a bridge unless there’s no other choice.Outline 1 Definitions 2 Euler’s Theorems 3 Fleury’s Algorithm 4 The Splicing Algorithm 5 Example 6 The Mail Carrier Problem Solved 7 Assignment Robb T.

Approach: To find cycle in a directed graph we can use the Depth First Traversal (DFS) technique. It is based on the idea that there is a cycle in a graph only if there is a back edge [i.e., a node points to one of its ancestors] present in the graph. To detect a back edge, we need to keep track of the nodes visited till now and the nodes that ...Use Fleury’s algorithm to find an Euler circuit; Add edges to a graph to create an Euler circuit if one doesn’t exist; In the first section, we created a graph of the Königsberg bridges and asked whether it was possible to walk across every bridge once.
