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.For all nodes in the graph, the program finds all Eulerian paths starting from that node. The relevant part of the program at this step is the function call "findPath' [ ("", node, g)] []". When you set out to find all Eulerian paths, the string indicating the current path is empty. As the graph is traversed, that string grows.An Eulerian cycle, Eulerian circuit or Euler tour in a undirected graph is a cycle with uses each edge exactly once.

Recall that a graph has an Eulerian tour iff there exists a path that starts and ends at the same vertex of the graph, visiting every vertex of the graph along the way and traversing each edge of the graph precisely once. Euler,Euler devised a mathematical proof by expressing the situation as a graph network. This proof essentially boiled down to the following statement (when talking about an undirected graph): An Eulerian path is only solvable if the graph is Eulerian, meaning that it has either zero or two nodes with an odd number of edges.An Eulerian trail (or Eulerian path) is a path that visits every edge in a graph exactly once.
