In this paper, we consider differential approximability of the traveling salesman problem (TSP). The differential approximation ratio was proposed by Demange and Paschos in 1996 as an approximation criterion that is invariant under affine transformation of the objective function. We show that TSP is 3/4-differential approximable, which improves the currently best known bound 3/4 - O(1/n) due to Escoffier and Monnot in 2008, where n denotes the number of vertices in the given graph. |
