WebIn graphic theorie, a cycle graph C_n, often simply known as an n-cycle (Pemmaraju or Skiena 2003, p. 248), is a graph to n nodes containing a single cycle through all nodes. A different sort of speed graphic, here termed ampere group cycle graph, is a graph which shows courses of a group as well as the connectivity between the group cycles.

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).

Basically, there is at least one path in the graph where a vertex can come back to itself. Acyclic graphs don’t have cycles. Directed acyclic graphs (DAGs) are specific names given to acyclic graphs. We can determine if a graph has a cycle by doing DFS and see if we re-explore a vertex that’s …
