Travelling Salesman Problem with a Center

Statistical Mechanics 2009-11-10 v2 Computational Complexity

Abstract

We study a travelling salesman problem where the path is optimized with a cost function that includes its length LL as well as a certain measure CC of its distance from the geometrical center of the graph. Using simulated annealing (SA) we show that such a problem has a transition point that separates two phases differing in the scaling behaviour of LL and CC, in efficiency of SA, and in the shape of minimal paths.
