摘要

This study provides speedup of the 2-Opt and 3-Opt processes by a new method based on Fourier descriptors (FDs) for the planar traveling salesman problem. By treating the planar tour as a closed contour, the proposed FD-based method, which is used as a potential swap identification function (PSIF), can limit the search space of 2-Opt/3-Opt by identifying the potential swap points/cities. In this article, approximate versions of the 2-Opt and 3-Opt procedures are adopted to investigate the performance of proposed PSIF. The experimental results using the proposed PSIF to reinforce the 3-Opt procedure show that the proposed method provides good quality solutions and faster computation. 2-Opt3-OptTSP2-Opt3-OptTSP 2-Opt3-Opt 2-Opt3-Opt 2-Opt3-Opt View full textDownload full textKeywordstraveling salesman problem, 2-Opt, 3-Opt, Fourier descriptorsKeywords : 2-Opt 3-Opt Related var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10170669.2011.553816
