Traveling Salesperson Problem: TSP is a problem that tries to find a tour of minimum cost that visits every city once. In this visualization, it is assumed that the underlying graph is a complete graph with (near-)metric distance (meaning the distance function satisfies the triangle inequality) by taking the distance of two points and round it to the nearest integer.
