Abstract—This paper proposes a problem-based heuristic performing well for solving asymmetric travelling salesman problem (ATSP), one of a well-known NP-hard problem. The basic concept of the proposed heuristic is to construct a round-trip route by moving from the current city to one of its adjacent cities systematically using a well selection procedure in its move’s direction. Based on its simple concept, this heuristic is thus very simple and can be calculated both by hand and by PC in a short time period. The experimental results show that the proposed heuristic outperforms the nearest neighbour algorithm.
