Euler path algorithm.

Fleury’s Algorithm is used to display the Euler path or Euler circuit from a given graph. In this algorithm, starting from one edge, it tries to move other adjacent vertices by removing the previous vertices. Using this trick, the graph becomes simpler in each step to find the Euler path or circuit.

I would like to know if there is a better algorithm, and if yes the idea behind it. Thanks in advance! Hierholzer’s algorithm to find Euler path – undirected graph. An Euler path is a trail in a graph that visits every edge exactly once. Here we use graph data structure to simulate the set of linked porker cards and find the Euler path between them. In a porker game, if two poker cards have matched suites and figures, they can be link together.
