Differential approximation results for the traveling salesman problem with distances 1 and 2

A NEW HEURISTIC FOR THE TRAVELING SALESMAN PROBLEM 251 Though simulated annealing [4] gives good results, it seems that the best heuristic for the symmetrie TSP is the one of Lin

We prove that the Christofides algorithm gives a | approx- imation ratio for the special case of traveling salesman problem (TSP) in which the maximum weight in the given graph is

Given a specific traveling route to visit all cities, c max denotes the maximum possible cost (the highest cost is chosen between every pair of consecutively visited cities on

MMAS has been improved with the integration of a local search. The 2-opt operator has been applied to the best ant before the pheromone update [13]. This method has also improved

We first prove that the minimum and maximum traveling salesman prob- lems, their metric versions as well as some versions defined on parameterized triangle inequalities

Other variants of the maximum traveling salesman problem that have been considered are among others: the maximum symmetric traveling salesman problem (MAX TSP), in which the
