In this post, we’ll learn how to improve TSP tours using a well known and approved local search improvement heuristic approach. These improvement heuristics start with an initial solution and iteratively improve it until no further improvement is possible, then return the best solution found. Previously, we discussed how to generate initial solutions for TSP… Read more How to Improve TSP-Tours Applying the 2-opt Neighborhood
In this post, we develop a construction heuristic to generate a first solution to the Traveling Salesman Problem (TSP). This is a simple heuristic which starts from an arbitrarily chosen location and then visits the nearest neighbor until all nodes have been visited. Finally, the tour is completed by returning to the starting node. Problem… Read more Construct TSP Solutions with the Nearest Neighbor Heuristic
This post shows a simple implementation using R to solve a given TSP (Traveling Salesperson Problem) instance using the Pilot Method. The whole R script can be accessed here on my gist. How does the Pilot Method work? The Pilot Method is a construction heuristic to build (i.e. initial) solutions. The method tries to avoid… Read more Solve TSP using Pilot Method
