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 it is connected and each vertex has an even degree.Author: Alexa Ryder

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.

Euler Paths and Circuits - Discrete Mathematics

http://discrete.openmathbooks.org/dmoi2/sec_paths.html

An Euler path, in a graph or multigraph, is a walk through the graph which uses every edge exactly once. An Euler circuit is an Euler path which starts and stops at the same vertex. Our goal is to find a quick way to check whether a graph (or multigraph) has an Euler path or circuit. Which of the graphs below have Euler paths?
