Apr 23, 2022 · What are Euler circuits used for? Rather than finding a minimum spanning tree that visits every vertex of a graph, an Euler path or circuit can be used to find a way to visit every edge of a graph once and only once. This would be useful for checking parking meters along the streets of a city, patrolling the streets of a city, or delivering mail.

Defitition of an euler graph "An Euler circuit is a circuit that uses every edge of a graph exactly once. An Euler path starts and ends at different vertices. An Euler circuit starts and ends at the same vertex." According to my little knowledge "An eluler graph should be degree of all vertices is even, and should be connected graph".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.

This situation does not appear in the Königsberg problem and, therefore, has been ignored until now. In the situation with a landmass X with an even number of bridges, two cases can occur.Euler Paths exist when there are exactly two vertices of odd degree. Euler circuits exist when the degree of all vertices are even. A graph with more than two odd vertices will never have an Euler Path or Circuit. A graph with one odd vertex will have an Euler Path but not an Euler Circuit.an Euler circuit, an Euler path, or neither. This is important because, as we saw in the previous section, what are Euler circuit or Euler path questions in theory are real-life routing questions in practice. The three theorems we are going to see next (all thanks to Euler) are surprisingly simple and yet tremendously useful.
