WebEuler 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. In the graph shown below, there are several Euler paths. One such path is CABDCB. The path is shown in arrows to the right, with the order of edges numbered. Webis that Euler solved this problem by inventing and then using Graph Theory (disputed by our author – see the footnote on p. 571.

WebApr 10, 2024 · If a graph has a Eulerian circuit, then that circuit also happens to be a path (which might be, but does not have to be closed). – dtldarek. Apr 10, 2024 at 13:08. If "path" is defined in such a way that a circuit can't be a path, then OP is correct, a graph with an Eulerian circuit doesn't have an Eulerian path. – Gerry Myerson.
