Finding Sparse Solutions for Packing and Covering Semidefinite Programs

Khaled Elbassioni, Kazuhisa Makino

摘要:

包装和覆盖半定规划(SDP)出现在许多组合优化问题的自然松弛以及许多其他应用。最近,提出了几种技术,利用这类问题的特定结构,以获得更有效的算法比一般SDP求解器提供的。对于某些应用,例如本文中描述的那些应用,可能期望获得{ \it稀疏}对偶解,即,那些支持大小(几乎)独立于原始约束的数量。在本文中,我们给出了一个算法,找到这样的解决方案,这是一个扩展的{ \it的势能}为基础的算法Grigoriadis,Khachiyan,Porkolab和Villavicencio(SIAM优化杂志41(2001))包装/覆盖线性规划。

英文摘要:

Packing and covering semidefinite programs (SDPs) appear in natural relaxations of many combinatorial optimization problems as well as a number of other applications. Recently, several techniques were proposed, that utilize the particular structure of this class of problems, to obtain more efficient algorithms than those offered by general SDP solvers. For certain applications, such as those described in this paper, it may be desirable to obtain {\it sparse} dual solutions, i.e., those with support size (almost) independent of the number of primal constraints. In this paper, we give an algorithm that finds such solutions, which is an extension of a {\it logarithmic-potential} based algorithm of Grigoriadis, Khachiyan, Porkolab and Villavicencio (SIAM Journal of Optimization 41 (2001)) for packing/covering linear programs.
