Abstract:

We show that an instance of traveling salesman problem (TSP) of size n with an asymmetric distance matrix can be transformed into an instance of TSP of size 2n with a symmetric distance matrix. This is an improvement over earlier transformations of this kind which triple the size of the problem. Next we use this transformation to obtain a Hamiltonian tour of a general TSP (which may be asymmetric and/or nonEucledian) with the worst case performance ratio of 20 9 when the ratio fl:= dmax dmin is smaller than 4 3, and (
