Travelling salesman problem (TSP) is one of the famous discrete optimization problems. Due to its NP-completeness, the exact methods are not found till now. Here we use a nearest neighbor method to search the approximations with a frequency graph. The frequency graph is computed with a set of local optimal paths derived from a weighted graph. The frequencies on the edges represent the number of edges...
Traveling salesman problem (TSP) becomes hard when the number of cities and routes are large. the ant colony optimization method (ACO) is enhanced with the four vertices and three lines inequality to search the optimal Hamiltonian circuit (OHC). the four vertices and three lines inequality is the constraint of the local optimal Hamiltonian paths (LOHP) and all the LOHPs in the OHC conform to the inequality...
