WebMay 31, 2015 · Python Traveling Salesman Greedy Algorithm. The Traveling Salesman Problem (TSP) is a combinatorial optimization problem, where given a map (a set of cities and their positions), one wants to find an order for visiting all the cities in such a way that the travel distance is minimal. I would suggest solving the tsp and then solve the visual stuff.

WebI'm trying to develop 2 different algorithms for Travelling Salesman Algorithm (TSP) which are Nearest Neighbor and Greedy. I can't figure out the differences between them while thinking about cities. I think they will follow the same way because shortest path between two cities is greedy and the nearest at the same time. which part am i wrong?
