Example of euler path and circuit

Example The graph below has several possible Euler circuits. Here’s a couple, starting and ending at vertex A: ADEACEFCBA and AECABCFEDA. The second is shown in arrows. Look back at the example used for Euler paths—does that graph have an Euler circuit? A few tries will tell you no; that graph does not have an Euler circuit.

An Eulerian graph is a special type of graph that contains a path that traverses every edge exactly once. It starts at one vertex (the “initial vertex”), ends at …circuit. Vertices and/or edges can be repeated in a path or in a circuit. (A path is called a walk by some authors. Due to the diversity of people who use graphs for their own purpose, the naming of certain concepts has not been uniform in graph theory). For example in the graph in Figure 3c, (a,b)(b,c)(c,e)(e,d)(d,c)(c,a) is an Eulerian ... An Euler path, in a graph or multigraph, is a walk through the graph which uses every edge exactly once.

Exactly two nodes have an odd degree, so there is an Eulerian path between nodes 2 ...A circuit is a path that begins and ends at the same vertex. Notice that a circuit is a kind of path and, therefore, is also a kind of walk. We will use the graph below to classify sequences as walks, paths or circuits.

If G is connected and has all valences even, then G has an Euler circuit. 2. Conversely, if G has an Euler circuit, then G must be connected and all its valences must be even. Even though a graph may not have an Euler circuit, it is possible to eulerize it so that it does. 2When a short circuit occurs, electrical current experiences little to no resistance because its path has been diverted from its normal direction of flow. This in turn produces excess heat and can damage or destroy an electrical appliance.An Euler circuit must include all of the edges of a graph, but there is no requirement that it traverse all of the vertices. What is true is that a graph with an Euler circuit is connected if and only if it has no isolated vertices: any walk is by definition connected, so the subgraph consisting of the edges and vertices making up the Euler ...Euler Paths exist when there are exactly two vertices of odd degree.
