WebA Hamilton cycle in a graph is a cycle that passes through every vertex of the graph. A graph is called Hamiltonian if it contains such a cycle. The problem of determining if a graph is Hamiltonian has been studied extensively, and there are many known sufficient conditions for Hamiltonicity. WebSep 2, 2024 · A Cycle Graph is 2-edge colorable or 2-vertex colorable, if and only if it has an even number of vertices. A Cycle Graph is 3-edge colorable or 3-edge colorable, if and only if it has an odd number of vertices. In a Cycle Graph, Degree of each vertex in a graph is two. The degree of a Cycle graph is 2 times the number of vertices. 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.
