An Euler tour or Eulerian tour in an undirected graph is a tour/ path that traverses each edge of the graph exactly once. Graphs that have an Euler tour are called Eulerian graphs. Necessary and sufficient conditions. An undirected graph has a closed Euler tour if and only if it is connected and each vertex has an even degree.Author: Alexa Ryder

Jul 27, 2014 · Eulerian Circuit is an Eulerian Path which starts and ends on the same vertex. A graph is said to be eulerian if it has a eulerian cycle. We have discussed eulerian circuit for an undirected graph. In this post, the same is discussed for a directed graph. For example, the following graph has eulerian cycle as {1, 0, 3, 4, 0, 2, 1}3.7/5

Jun 13, 2013 · A graph is called Eulerian if it has an Eulerian Cycle and called Semi-Eulerian if it has an Eulerian Path. The problem seems similar to Hamiltonian Path which is NP complete problem for a general graph. Fortunately, we can find whether a given graph has a Eulerian …3.3/5

Euler Tour: Euler Tour of a tree is defined as the path traversed in the graph such that each vertex is added to the path as it is visited. This includes both entering from parent to child and child to parent traversal. The tour starts from the root and ends at the root …

The travelers visits each city (vertex) just once but may omit several of the roads (edges) on the way. Eulerian Trail. A connected graph G is Eulerian if there is a closed trail which includes every edge of G, such a trail is called an Eulerian trail.
