WebThe Hamiltonian Cycle Problem (HCP) is a well known NP-complete problem (see for example Cormen et al. [1] or Johnson and Papadimitriou [5]). Given a graph G =(V,E), can a cycle be found that visits every vertex v ∈ V exactly once. Such a cycle is known as a Hamiltonian Cycle (HC), and a graph G with an HC is called Hamiltonian.
