NettetAn Eulerian path on a graph is a traversal of the graph that passes through each edge exactly once. It is an Eulerian circuit if it starts and ends at the same vertex. _\square . The informal proof in the previous section, translated into the language of graph theory, shows immediately that: If a graph admits an Eulerian path, then there are ... Nettet7. jul. 2024 · We will state it for multigraphs, as that makes the corresponding result about Euler trails a very easy corollary. Theorem 13.1. 1 A connected graph (or multigraph, with or without loops) has an Euler tour if and only if every vertex in the graph has even valency. Proof Example 13.1. 2 NettetA graph G = ( V, E) is a structure consisting of a set of objects called vertices V and a set of objects called edges E . An edge e ∈ E is denoted in the form e = { x, y }, where the vertices x, y ∈ V. Two vertices x and y connected by the edge e = { x, y }, are said to be adjacent , with x and y ,called the endpoints. radnage ce infant school
