Polynomial Time Data Reduction for Dominating Set

Jochen Alber, Michael R. Fellows, Rolf Niedermeier

摘要:

处理NP完全支配集问题的无向图,我们证明了权力的数据减少预处理从理论和实践方面。特别是,我们证明了限制平面图的支配集有一个所谓的问题核的线性大小,实现了两个简单,易于实现的减少规则。此外,实施我们的减少规则,第一次实验表明,这些规则的令人印象深刻的实际潜力。因此,本文的工作似乎为解决图论和组合优化中的一个重要问题开辟了一条新的、有前途的途径。

英文摘要:

Dealing with the NP-complete Dominating Set problem on undirected graphs, we demonstrate the power of data reduction by preprocessing from a theoretical as well as a practical side. In particular, we prove that Dominating Set restricted to planar graphs has a so-called problem kernel of linear size, achieved by two simple and easy to implement reduction rules. Moreover, having implemented our reduction rules, first experiments indicate the impressive practical potential of these rules. Thus, this work seems to open up a new and prospective way how to cope with one of the most important problems in graph theory and combinatorial optimization.
