This is an important concept in Graph theory that appears frequently in real ... In graph theory, an Eulerian trail is a trail in a finite graph that visits every edge exactly once . Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex. They were first discussed by Leonhard Euler while solving the famous Seven Bridges of Königsberg problem in 1736. The problem can be stated mathematically like this:1. @DeanP a cycle is just a special type of trail. A graph with a Euler cycle necessarily also has a Euler trail, the cycle being that trail. A graph is able to have a trail while not having a cycle. For trivial example, a path graph. A graph is able to have neither, for trivial example a disjoint union of cycles. – JMoravitz.Here is Euler’s method for finding Euler tours. We will state it for multigraphs, as that makes the corresponding result about Euler trails a very easy corollary. Theorem 13.1.1 13.1. 1.

This patching together of circuits hinges of course, on the circuits having a common vertex, and this fact follows from the connectivity of the graph. Once one circuit is formed, if all edges have not been used, then there must be one edge that is incident to a vertex of the circuit, and we use this edge to begin the next ...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. 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.A walk from vi to itself with no repeated edges is called a cycle with base vi. Then the examples in a graph which contains loop but the examples don't mention any loop as a cycle. "Finally, an edge from a vertex to itself is called a loop. There is loop on vertex v3". Seems to me that they are different things in the context of this book.
