WIN algorithm for discrete online TSP

Wu, Yonghua and Zhu, Guohun and Chen, Huaying and Qin, Jucun (2011) WIN algorithm for discrete online TSP. Journal of Advanced Computational Intelligence and Intelligent Informatics, 15 (9). pp. 1199-1202. ISSN 1343-0130


Traveling Salesman Problem (TSP) which is proved as an NP-Complete problem is solved by many algorithms. In this paper, we propose online TSP which is based on general discrete metric space. A Waiting- If-Necessary (WIN) algorithm is proposed that involves with increasing cost caused by zealous algorithms and unnecessary waiting caused by cautious algorithms. We measure the performance of the WIN algorithm using competitive analysis and found that it is a 2-competitive algorithm. The competitive ratio of theWIN algorithm can be improved by setting parameter T0.
