Nevertheless, one may appl y methods for the TSP to find good feasible solutions for this problem (see Lenstra & Rinnooy Kan, 1974). In this research, he solved the problem with Ant Colony, Simulated Annealing and Genetic Algorithms., but the best results that he obtained were with Genetic Algorithms. %���� This problem is called the Traveling salesman problem (TSP) because the question can be framed like this: Suppose a salesman needs to give sales pitches in four cities. ��0M�70�Զ�e)\@ ��+s�s���8N��=&�&=�6���y*k�oeS�H=�������â��`�-��#��A�7h@�"��씀�Л1 �D ��\? << Faster exact solution approaches (using linear programming).

Travelling Salesman Problem (TSP) : Given a set of cities and distances between every pair of cities, the problem is to find the shortest possible route that visits every city exactly once and returns to the starting point. More formally, a TSP instance is given by a complete graph G on a node set V = {1,2,… m }, for some integer m , and by a cost function assigning a cost c ij to the arc ( i,j ) , for startxref Download Full PDF Package. Let a network G = [N,A,C], that is N the set nodes, A the set of arcs, and C = [c ij] the cost matrix.That is, the cost of the trip since node i to node j.The TSP requires a Halmiltonian cycle in G of minimum cost, being a Hamiltonian cycle, one that passes to through each node i exactly once.
