摘要

本文给出了预算最大覆盖问题和广义最大覆盖问题对带冲突图的背包问题的近似保留缩减。这些约简用于这些问题的特殊类别实例的多项式时间近似格式。使用这些近似格式，证明了伪多项式算法的存在性，并且在更特殊的情况下，这些算法被证明具有多项式时间复杂度。此外，还分析了采用这些算法的实例的特点。

Approximations for Restrictions of The Budgeted and Generalized Maximum Coverage Problems

In this paper we present approximation preserving reductions from the Budgeted and Generalized Maximum Coverage Problems to the Knapsack Problem with Conflict Graphs. The reductions are used to yield Polynomial Time Approximation Schemes for special classes of instances of these problems. Using these approximation schemes, the existence of pseudo-polynomial algorithms are proven and, in more particular cases, these algorithms are shown to have polynomial time complexity. Moreover, the characteristics of the instances that admit these algorithms are analyzed.

期刊介绍： ENTCS is a venue for the rapid electronic publication of the proceedings of conferences, of lecture notes, monographs and other similar material for which quick publication and the availability on the electronic media is appropriate. Organizers of conferences whose proceedings appear in ENTCS, and authors of other material appearing as a volume in the series are allowed to make hard copies of the relevant volume for limited distribution. For example, conference proceedings may be distributed to participants at the meeting, and lecture notes can be distributed to those taking a course based on the material in the volume.
