8/7-approximation algorithm for (1,2)-TSP
@article{Berman200687approximationAF, title={8/7-approximation algorithm for (1,2)-TSP}, author={Piotr Berman and Marek Karpinski}, journal={Electron. Colloquium Comput. Complex.}, year={2006} }
We design a polynomial time 8/7-approximation algorithm for the Traveling Salesman Problem in which all distances are either one or two. This improves over the best known approximation factor for that problem. As a direct application we get a 7/6-approximation algorithm for the Maximum Path Cover Problem, similarly improving upon the best known approximation factor for that problem. The result depends on a new method of consecutive path cover improvements and on a new analysis of certain…Â

The Traveling Salesman Problem
- Computer Science
- 2012
The TSP is perhaps the best-studied NP-hard combinatorial optimization problem, and there are many techniques which have been applied, and so-called local search algorithms find better solutions for large instances although they do not have a finite performance ratio.
