Example of euler path and circuit.

Euler Paths. Each edge of Graph 'G' appears exactly once, and each vertex of 'G' appears at least once along an Euler's route. If a linked graph G includes an Euler's route, it is traversable.

An Euler circuit must include all of the edges of a graph, but there is no requirement that it traverse all of the vertices. What is true is that a graph with an Euler circuit is connected if and only if it has no isolated vertices: any walk is by definition connected, so the subgraph consisting of the edges and vertices making up the Euler ...

Euler path = BCDBAD. Example 2: In the following image, we have a graph with 6 nodes. Now we have to determine whether this graph contains an Euler path. Solution: The above graph will contain the Euler path if each edge of this graph must be visited exactly once, and the vertex of this can be repeated.Euler Path. An Euler path is a path that uses every edge in a graph with no repeats. Being a path, it does not have to return to the starting vertex. Example.
