Eulerian Path and Circuit Algorithm - How does it work?

Web7 de mai. de 2024 · As many other posts have suggested, this problem can be solved by finding the Eulerian path (a path that travels all edges exactly once) in a directed graph. There is a classic method known as the Hierholzer's algorithm for this purpose; it can easily be used in the DFS procedure. The normal DFS would visit all nodes exactly once, … WebVamos dar um exemplo: Let the initial directed graph be as below Let's start our path from 0.
