To read TSPLIB data, … The Travelling Salesman Problem (also known as the Travelling Salesperson Problem or TSP) is an NP-hard graph computational problem where the salesman must visit all cities (denoted using vertices in a graph) given in a set just once. The distances (denoted using edges in the graph) between all these cities are known. 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. Multiplicative decrease: Use T = a * T, where a is a constant like 0.99 . → Tn = an . Additive decrease: Use T = T - a, where a is a constant like 0.0001 . Inverse-log decrease: Use T = a / log (n) . In practice: need to experiment with different temperature schedules for a particular problem.
