For the best of the algorithms investigated in , R w → 2, as n, the number of cities in the travelling salesman problem (TSP), tends to be ∞. In this paper, we describe a heuristic algorithm with O(n 3) growth rate and for which R w < 3/2 for all n. This represents an improvement of 50% over the previously best known value of R w for the TSP.
