k-RNN:扩展TSP的NN算法

k-RNN: Extending NN-heuristics for the TSP

Nikolas Klug, Alok Chauhan, Ramesh Ragala, V Vijayakumar

摘要:

在本文中,我们提出了一个扩展现有的最近邻算法称为k-重复最近邻。我们的想法是从k个节点的巡回开始,然后从那里开始执行最近邻搜索。在对k个节点的所有排列执行此操作后,结果将被选择为找到的最短巡回。实验结果表明,对于2-RNN,解决方案质量保持相对稳定,在最佳值以上约10%至40%。

英文摘要:

In this paper we present an extension of existing Nearest-Neighbor heuristics to an algorithm called k-Repetitive-Nearest-Neighbor. The idea is to start with a tour of k nodes and then perform a Nearest-Neighbor search from there on. After doing this for all permutations of k nodes the result gets selected as the shortest tour found. Experimental results show that for 2-RNN the solutions quality remains relatively stable between about 10% to 40% above the optimum.
