Euler's circuit theorem

WebAn Euler path, in a graph or multigraph, is a walk through the graph which uses every edge exactly once. An Euler circuit is an Euler path which starts and stops at the same vertex. Our goal is to find a quick way to check whether a graph (or multigraph) has an Euler path or circuit. Which of the graphs below have Euler paths? WebEuler’s Circuit Theorem. (a) If a graph has any vertices of odd degree, then it cannot have an Euler circuit. (b) If a graph is connected and every vertex has even degree, then it …

WebOne more definition of a Hamiltonian graph says a graph will be known as a Hamiltonian graph if there is a connected graph, which contains a Hamiltonian circuit. The vertex of a graph is a set of points, which are interconnected with the set of lines, and these lines are known as edges. The example of a Hamiltonian graph is described as follows: WebMar 24, 2024 · Eulerian Cycle. Download Wolfram Notebook.

WebEuler's argument shows that a necessary condition for the walk of the desired form is that the graph be connected and have exactly zero or two nodes of odd degree. This condition turns out also to be sufficient—a result stated by Euler and later proved by Carl Hierholzer. Such a walk is now called an Eulerian path or Euler walk in his honor.
