The Hamiltonian path problem for general grid graphs is known to be NP- complete In this paper, we give necessary and sufficient conditions for the existence of
As a corollary we show that G, contains a Hamiltonian circuit if and only if n > 6 and n is even Our solution is based on an efficient backtracking algorithm for the
In this paper, we show that the Hamiltonian path completion problem will unlikely have any constant ratio approximation algorithm unless NP = P This problem
Definition A Hamiltonian cycle (or circuit) is a closed path that visits each vertex once Definition A graph that has a Hamiltonian cycle is called Hamiltonian

A Hamiltonian path in a directed graph is a directed path that goes through each node exactly once. The decision problem: Given a directed graph G and nodes
*Unlike Euler Paths and Circuits there is no trick to tell if a graph has a Hamilton Path or Circuit. A Complete Graph is a graph where every pair of vertices
Abstract. The problem of finding shortest Hamiltonian path and shortest Hamiltonian circuit in a weighted complete graph belongs to the class of NP-Complete.
