Ask Question Asked 2 years ago. Actually, I took part in a hackathon and was pretty busy. The salesman has to visit every one of the cities starting from a certain one (e.g., the hometown) and to return to the same city. It also can tackle what’s known as the traveling salesman problem (TSP)—the need to determine the most cost-efficient route across multiple destinations. Need a Web Site? Standalone Application?
