WebCycle: A closed path in the graph theory is also known as a Cycle. A cycle is a type of closed walk where neither edges nor vertices are allowed to repeat. There is a possibility … 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.

The vertices are sometimes also referred to as nodes and the edges are lines or arcs that connect any two nodes in the graph. More formally a Graph is composed of a set of vertices ( V ) and a set of edges ( E ). The graph is denoted by G (V, E).

Tree edges are edges in the search tree (or forest) constructed (implicitly or explicitly) by running a graph search algorithm over a graph. An edge (u,v) is a tree edge if v was first discovered while exploring (corresponding to the visitor explore() method) edge (u,v). Back edges connect vertices to their …
