摘要:
提出了设施选址问题的一个新变体—限制设施选址问题,给出了一个基于随机线性规划舍入的近似算法,并分析了算法的近似度。
关键词: 设施选址问题, 近似算法, 随机线性规划舍入
Abstract:
The paper presented an approximation algorithm for the Limited Facility Location problem (LFL), which is a new variant of the classical Uncapacitated Facility Location problem(UFL). The algorithm is based on randomized LP rounding, and its approximation ratio was analyzed.
Key words: facility location problem;approximation algorithm;randomized LP rounding
