Eulerian path - Wikipedia

https://en.wikipedia.org/wiki/Euler_tour

An Eulerian orientation of an undirected graph G is an assignment of a direction to each edge of G such that, at each vertex v, the indegree of v equals the outdegree of v. Such an orientation exists for any undirected graph in which every vertex has even degree, and may be found by constructing an Euler tour in each connected component of G ...

Euler_Tour(graph& G, list<edge>& T) The function returns true if the underlying undirected version of G has an Euler tour. G is reoriented such that every node has indegree equal to its outdegree and an Euler tour (of the reoriented graph) is returned in T. The running time is O(n + m). bool: Check_Euler_Tour(const graph& G, const list<edge>& T ...

An Euler Circuit is an Euler path or Euler tour (a path through the graph that visits every edge of the graph exactly once) that starts and ends at the same vertex. ... (indegree == outdegree + 1), this is the Euler path end vertex; Rest all vertices should have (indegree==outdegree) If any of above conditions fail, an Euler path cannot exist. ...

EULER TOUR TECHNIQUE An Euler circuit of a graph is an edge-disjoint circuit which traverses all the nodes. A graph permits an Euler circuit if and only if each vertex has equal indegree and outdegree. An Euler circuit can be used for optimal parallel computation of many tree functions. To construct an Euler circuit, we have to

https://math.stackexchange.com/questions/1249979/the-graph-has-an-euler-tour-iff-in-degreev-out-degreev

In a simple cycle the in degree and the out degree are both one, so if we add to some simple cycle another simple cycle at some vertex, the in degree and the out degree of the vertex will increase both by 1.

Nov 13, 2017 · Graph Theory dates back to times of Euler when he solved the Konigsberg bridge problem. Any graph can be seen as collection of nodes connected through edges. Mathematically this is represented as G = [V,E] (a notation, nothing to worry about if it...
