Eulers path.

1. One way of finding an Euler path: if you have two vertices of odd degree, join them, and then delete the extra edge at the end. That way you have all vertices of even degree, and your path will be a circuit. If your path doesn't include all the edges, take an unused edge from a used vertex and continue adding unused edges until you get a ...According to Wikipedia, Eulerian Path (also called Eulerian Trail) is a path in a finite graph that visits every edge exactly once. The path may be started and ended at different graph vertices.Derivations. Euler’s formula can be established in at least three ways. The first derivation is based on power series, where the exponential, sine and cosine functions are expanded as power series to conclude that the formula indeed holds..

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.

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).
