Graph self-loop

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 … WebMar 22, 2024 · Approach: To find cycle in a directed graph we can use the Depth First Traversal (DFS) technique. It is based on the idea that there is a cycle in a graph only if there is a back edge [i.e., a node points to one of …
