We consider the asymmetric traveling salesperson problem with /gamma-parameterized triangle inequality Chandran and Ram recently gave the first constant factor approximation algorithm with polynomial running time for this problem. We devise an approximation algorithm, which is better than the one of Chandran and Ram for /gamma in [0.5437,1).
