关于广义最小和集覆盖问题的一个注记
A note on the generalized min-sum set cover problem
摘要:
在本文中,我们考虑广义最小和集覆盖问题,介绍了Azar,Gamzu,和尹。Bansal、Gupta和Krishnaswamy给出了一个485-近似算法。我们能够改变他们的算法和分析,以获得一个28-近似算法,提高了一个数量级的性能保证。我们使用的概念,从$α$点调度,以获得我们的改进。
英文摘要:
In this paper, we consider the generalized min-sum set cover problem, introduced by Azar, Gamzu, and Yin. Bansal, Gupta, and Krishnaswamy give a 485-approximation algorithm for the problem. We are able to alter their algorithm and analysis to obtain a 28-approximation algorithm, improving the performance guarantee by an order of magnitude. We use concepts from $α$-point scheduling to obtain our improvements.
