TSP is a classical example of optimization and constrain satisfaction problem which falls under the family of NP-complete of problems. I have discussed an implementation of an algorithm in neural network for an approximate solution for Travelling Salesman’s Problem. Now I used Continuous Hopfield network to find the solution for the given problem. The algorithm gives near optimal result in most of the cases for up to 100 cities.
