Euler Tour of Tree

https://www.geeksforgeeks.org/euler-tour-tree/

Mar 30, 2018 · Euler tour is defined as a way of traversing tree such that each vertex is added to the tour when we visit it (either moving down from parent vertex or returning from child vertex). We start from root and reach back to root after visiting all vertices. It requires exactly 2*N-1 vertices to store Euler tour.2/5

Aug 03, 2013 · 1. Make sure the graph has either 0 or 2 odd vertices. 2. If there are 0 odd vertices, start anywhere. If there are 2 odd vertices, start at one of them. 3. Follow edges one at a time. If you have a choice between a bridge and a non-bridge, always choose the non-bridge. 4. Stop when you run out of ...4.2/5

part, we describe an algorithm to find an Euler tour of graph if one exists. Part 1 Show that G has an Euler tour if and only if in-degree(v) = out-degree(v) for each vertex vÎV

What is a Euler or Eulerian tour?

https://iq.opengenus.org/what-is-a-euler-or-eulerian-tour/

An Euler tour or Eulerian tour in an undirected graph is a tour/ path that traverses each edge of the graph exactly once. Graphs that have an Euler tour are called Eulerian graphs. Necessary and sufficient conditions An undirected graph has a closed Euler tour if and only if …Author: Alexa Ryder

Fleury's algorithm: Find Euler or Eulerian tour in a graph

https://iq.opengenus.org/fleury-algorithm-finding-eulerian-tours-in-a-graph/

Fleury's algorithm is a simple algorithm for finding Eulerian paths or tours. It proceeds by repeatedly removing edges from the graph in such way, that the graph remains Eulerian. The steps of Fleury's algorithm is as follows: Start with any vertex of non-zero degree.Author: Alexa Ryder
