Graphe cycle
WebMar 24, 2024 · In graph theory, a cycle graph C_n, sometimes simply known as an n-cycle (Pemmaraju and Skiena 2003, p. 248), is a graph on n nodes containing a single cycle through all nodes. A different sort of cycle graph, here termed a group cycle graph, is a graph which shows cycles of a group as well as the connectivity between the group … WebDans un graphe non orienté, un cycle est une suite d'arêtes consécutives distinctes ( chaine simple) dont les deux sommets extrémités sont identiques. Dans les graphes orientés, la notion équivalente est celle de circuit, même si on parle parfois aussi de cycle (par exemple dans l'expression graphe acyclique orienté ).

WebMar 22, 2024 · 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 its … A chordless cycle in a graph, also called a hole or an induced cycle, is a cycle such that no two vertices of the cycle are connected by an edge that does not itself belong to the cycle. An antihole is the complement of a graph hole. Chordless cycles may be used to characterize perfect graphs: by the strong perfect … See more In graph theory, a cycle in a graph is a non-empty trail in which only the first and last vertices are equal.
