This is also ... Finding an Euler Circuit or Euler Path Euler's theorems tell us if a path exists but not how to find it. Basic idea for a method: Avoid bridges unless there is no other option. Once we cross a bridge we leave a component of the graph and cannot get back to it. Important: be organized and clear in which edges you have used. Eulerization. Eulerization is the process of adding edges to a graph to create an Euler circuit on a graph. To eulerize a graph, edges are duplicated to connect pairs of vertices with odd degree. Connecting two odd degree vertices increases the degree of each, giving them both even degree.(definition) Definition: A path through a graph which starts and ends at the same vertex and includes every edge exactly once.
