WebMay 8, 2013 · Let A be the adjacency matrix for the graph G = (V,E). A (i,j) = 1 if the nodes i and j are connected with an edge, A (i,j) = 0 otherwise. My objective is the one of understanding whether G is acyclic or not. A cycle is defined in the following way: i and j are connected: A (i,j) = 1. j and k are connected: A (j,k) = 1. 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 ).

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. A directed cycle in a directed graph is a non-empty directed trail in which only the first and last vertices are equal. See more Circuit and cycle • A circuit is a non-empty trail in which the first and last vertices are equal (closed trail).
