Travelling salesman problem solver

The Travelling Salesman Problem (TSP) is a problem in combinatorial optimization. Given a list of cities and their pairwise distances, the task is to find a shortest possible tour that visits each city exactly once. TGoogleMaps can solve this problem with 2 different way:

• find the route from an address A to an address B;
• find the route from an address A to the same address A;
