- Abstract
- As the traveling salesman problem is NP-hard, many heuristics have been developed. Among heuristics, Kwon
algorithm efficiently finds optimum or near-optimum by applying the optimal algorithm, Out-of-Kilter to the
asymmetric traveling salesman problem. But characteristics of out-of-kilter arc of the algorithm are not clear. This
paper presents the properties of out-of-kilter arcs, change of the number of out-of-kilter arcs, residual number of outof-kilter arcs, and the number of exchanging arcs when we implement the Kwon algorithm. For test bed, we used 27
real-world TSPLIB problems and 220 randomly generated problems. Test results show that initial number of out-ofkilter arcs is affected by the range of cost and initial solution quality, and the algorithm exchanges general odd or even
number of arcs. And average 2.2% of the number of initial out-of-kilter arcs was remained when it found a solution.
