Abstract

We given a constant factor $(\frac{\gamma} {1-\gamma} + \gamma)$ approximation for the asymmetric traveling salesman problem in graphs with costs on the edges satisfying \gamma –parameterized triangle inequality ( \gamma –Asymmetric graphs) for $\gamma \in [\frac{1} {2}, 1]$. We also give an improvement of the algorithm with approximation factor approaching $\frac{\gamma} {1-\gamma}$.
