WebAug 29, 2024 · If the graph had n of these cycles and we added the edge we would create 2 n new cycles. For another example, taking the complete graph K n without an edge and adding in that edge creates n − 2 + ( n − 2) ( n − 3) + ( n − 2) ( n − 3) ( n − 4) + ⋯ + ( n − 2)! new 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 graph … 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.
