Jul 27, 2014 · A directed graph has an eulerian cycle if following conditions are true (Source: Wiki) 1) All vertices with nonzero degree belong to a single strongly connected component. 2) In degree is equal to the out degree for every vertex. We can detect singly connected component using Kosaraju’s DFS based simple algorithm.3.7/5

complex cycle (and in particular an Euler tour) has in-degree equal to its out-degree. Thus, if a graph has an Euler tour than all of its vertices have equal in- and out- degrees. Now look at the <= direction.

What is a Euler or Eulerian tour?

Similarly, a directed graph has an open Euler tour (Euler path) if and only if for each vertex the difference between its in-degree and out-degree is 0, except for two vertices, where one has difference +1 (the start of the tour) and the other has difference -1 (the end of the tour) and, if you add an edge from the end to the start, the graph is strongly connected.Author: Alexa Ryder

Aug 23, 2019 · An Euler circuit always starts and ends at the same vertex. A connected graph G is an Euler graph if and only if all vertices of G are of even degree, and a connected graph G is Eulerian if and only if its edge set can be decomposed into cycles. The above graph is an Euler graph as a 1 b 2 c 3 d 4 e 5 c 6 f 7 g covers all the edges of the graph ...
