Hello, I've been making myself familiar with Drools Planner and in the process of doing so, I've hacked together a simple algorithm for optimizing the Travelling Salesman Problem:
https://github.com/triceo/DroolingTSP At this point, I get a 7 % improvement over a route with 71 stops, which was previously assembled using a nearest-neighbor algorithm. The reason why the improvement isn't bigger is that I'm stuck with Tabu search only - for my use case, simulated annealing doesn't work at all. (Exits forcefully after 1 to 7 steps, resulting in only a minimal improvement.) I'll be interested in any comments and suggestions you might be able to provide.
