Fleury’s Algorithm: Erasing edges in a graph with no odd vertices and keeping track of your progress to find an Euler Circuit. a. Begin at any vertex, since they are all even. A graph may have more than 1 circuit). b.In graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex. They were first discussed by Leonhard Euler while solving the famous Seven ...
