Yes, definitely a problem I was studying at school. We are studying bitonic tours for the traveling salesman problem. Anyway, say I have 5 vertices {0,1,2,3,4}. I know my first step is to sort these in order of increasing x-coordinates. From there, I am a bit confused on how this would be done with dynamic programming Here problem is travelling salesman wants to find out his tour with minimum cost. Say it is T (1,{2,3,4}), means, initially he is at village 1 and then he can go to any of {2,3,4}. From there to reach non-visited vertices (villages) becomes a new problem In addition to finding solutions to the classical Traveling Salesman Problem, OR-Tools also provides methods for more general types of TSPs, including the following: Asymmetric cost problems — The traditional TSP is symmetric: the distance from point A to point B equals the distance from point B to point A
