摘要

本文考虑了在WDM网络上有效放置波长转换器的无向反馈顶点集问题的大小约束版本，并证明了该问题在一些特殊情况下是np完全的。此外，本文还提出了一种简单的逼近算法，利用原始的最小无向反馈顶点集问题的算法来求解该问题的最小化版本。

The undirected feedback vertex set problem with application to wavelength converter placement on WDM networks

This paper considers a size constrained version of the undirected feedback vertex set problem motivated by placing wavelength converters on a WDM network efficiently, and proves that this problem is NP-complete even in several special cases. Moreover, the paper presents a simple approximation algorithm for a minimization version of the problem using an algorithm for the original minimum undirected feedback vertex set problem.
