Hamiltonian path problem - Wikipedia

https://en.wikipedia.org/wiki/Hamiltonian_path_problem

In the mathematical field of graph theory the Hamiltonian path problem and the Hamiltonian cycle problem are problems of determining whether a Hamiltonian path (a path in an undirected or directed graph that visits each vertex exactly once) or a Hamiltonian cycle exists in a given graph (whether directed or undirected).Both problems are NP-complete.. The Hamiltonian cycle problem is a special ...

Problem: Given a complete undirected graph G=(V, E) that has nonnegative integer cost c(u, v) associated with each edge (u, v) in E, the problem is to find a hamiltonian cycle (tour) of G with minimum cost. A salespersons starts from the city 1 and has to visit six cities (1 through 6) and must come back to the starting city i.e., 1. The first route (left side) 1→ 4 → 2 → 5 → 6 → 3 ...

Whether a graph does or doesn't have a Hamiltonian circuit is an "NP-hard" problem, i.e an exponential type problem: for a graph involving n vertices any known algorithm would involve at least 2 n steps to solve it. Finding a Hamiltonian circuit may take n! many steps and n! > 2 n for most n.. Example 6:
