FLSSS:求解子集和族组合优化问题的一个新的数学框架

FLSSS: A Novel Algorithmic Framework for Combinatorial Optimization Problems in the Subset Sum Family

Charlie Wusuo Liu

摘要:

本文详细介绍了FLSSS中的算法,FLSSS是一个用于解决各种子集和问题的R软件包。基本算法通过组合空间压缩来解决问题,这些压缩适应于约束、松弛和变化,这些约束、松弛和变化通常对实践中的数据分析至关重要。相反,这种适应性使压缩算法能够耗尽排序超集可能带来的每一位信息,以实现快速收敛。多维扩展遵循一个新的问题分解,是友好的多线程。支持这些算法的数据结构具有微不足道的空间复杂度。该框架提供了多维背包问题和广义指派问题的精确算法。

英文摘要:

This article details the algorithmics in FLSSS, an R package for solving various subset sum problems. The fundamental algorithm engages the problem via combinatorial space compression adaptive to constraints, relaxations and variations that are often crucial for data analytics in practice. Such adaptation conversely enables the compression algorithm to drain every bit of information a sorted superset could bring for rapid convergence. Multidimensional extension follows a novel decomposition of the problem and is friendly to multithreading. Data structures supporting the algorithms have trivial space complexity. The framework offers exact algorithms for the multidimensional knapsack problem and the generalized assignment problem.
