Fleury’s algorithm will provide a procedure to find an Euler Circuit or an Euler Path (when we already know that one exists in a particular graph). In order to understand Fleury’s algorithm we need to know the term bridge. Well, you know what a bridge is but remember in graph theory things like walk or path have special meaning.An Euler path is a path that uses every edge of the graph exactly once. Edges cannot be repeated. This is an important concept in designing real life solutions. In this article, we have explored the basic ideas/ terminologies to understand Euler Path and related algorithms like Fleury's Algorithm and Hierholzer's algorithm.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.
