An Eulerian trail (also known as an Eulerian path) is a finite graph trail in graph theory that reaches each edge exactly once (allowing for revisiting vertices). An analogous Eulerian trail that begins and finishes at the same vertex is known as an Eulerian circuit or cycle.Section 5. Euler’s Theorems. Recall: an Euler path or Euler circuit is a path or circuit that travels through every edge of a graph once and only once.

An undirected graph has an Eulerian cycle if and only if. Every vertex has an even degree, andIn 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: Proof: If G is Eulerian then there is an Euler circuit, P, in G. Every time a vertex is listed, that accounts for two edges adjacent to that vertex, the one before it in the list and the one after it in the list. This circuit uses every edge exactly once. So every edge is accounted for and there are no repeats. Thus every degree must be even.What is an Euler Path and Circuit? For a graph to be an Euler circuit or path, it must be traversable. This means you can trace over all the edges of a graph exactly once without lifting your pencil. This is a traversal graph! Try it out: Euler Circuit For a graph to be an Euler Circuit, all of its vertices have to be even vertices. An Eulerian path, also called an Euler chain, Euler trail, Euler walk, or "Eulerian" version of any of these variants, is a walk on the graph edges of a graph which uses each graph edge in the original graph exactly once. A connected graph has an Eulerian path iff it has at most two graph vertices of odd degree.Dec 7, 2021 · An Euler path (or Euler trail) is a path that visits every edge of a graph exactly once. 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.
