In modern graph theory, an Eulerian path traverses each edge of a graph once and only once. Thus, Euler’s assertion that a graph possessing such a path has at most two vertices of odd degree was the first theorem in graph theory.

Similarly, an Euler circuit (or Euler cycle) is an Euler trail that starts and ends on the same node of a graph. A graph having Euler path is called Euler graph. While tracing Euler graph, one may halt at arbitrary nodes while some of its edges left unvisited.Unfortunately, in contrast to Euler’s result about Euler tours and trails (given in Theorem 13.1.1 and Corollary 13.1.1), there is no known characterisation that enables us to quickly determine whether or not an arbitrary graph has a Hamilton cycle (or path). This is a hard problem in general.Introduction: A Graph is a non-linear data structure consisting of vertices and edges. The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (V, E).

An Eulerian path on a graph is a traversal of the graph that passes through each edge exactly once, and the study of these paths came up in their relation to problems studied by Euler in the 18th century like the one below: No Yes Is there a walking path that stays inside the picture and crosses each of the bridges exactly once?
