A vertex can form an edge with all other vertices except by itself. So the degree of a vertex will be up to the number of vertices in the graph minus 1. This 1 is for the self-vertex as it cannot form a loop by itself. tryon presbyterian

For example: can be simplified by eliminating the self-loop. We multiply WebA cycle in a graph is, according to Wikipedia, An edge set that has even degree at every vertex; also called an even edge set or, when taken together with its vertices, an even subgraph. In your case, the single vertex has a degree of 2, which is even. Therefore the self-loop is a cycle in your graph.

WebJul 20, 2024 · I think the strongly connected components should be {A} and {B} (because of this algorithm and this answer here for undirected graph: Singleton graph/single node is connected). But I am confused because of two reasons: one this is a directed graph, and two there no self loop on either A or B, so I am confused whether A/B is reachable by A/B. WebFeb 19, 2024 · A student in my graph algorithms class asked how self-loops in undirected graphs affect the vertex degrees and matchings of a graph. The standard answer is that a self-loop adds two to the degree (because each edge has two endpoints) and that they are useless in matching because matchings should have at most one incidence to each …
