Example of traveling salesman problem
The traveling salesperson problem is one of a handful of foundational problems that theoretical computer scientists turn to again and again to test the limits of efficient computation. The new result “is the first step towards showing that the frontiers of efficient computation are in fact better than what we thought,” Williamson said.example, the traveling salesman could just visit all cities in the order in which they appear in the input. In these cases the problem is really that we have to find an optimal solution. In the case of linear programming, it is different: here it is already difficult to find just any solution that satisfies all inequalities.Finding the shortest route travelled by the salesman is one of the computational problems, which can be optimized by using Hopfield neural network. Basic Concept of TSP Travelling Salesman Problem (TSP) is a classical optimization problem in which a salesman has to travel n cities, which are connected with each other, keeping the cost as well as the …
