约束求解器:设计决策的经验评估

Constraint solvers: An empirical evaluation of design decisions

Lars Kotthoff

摘要:

本文提出了一种评估的设计决策,在四个国家的最先进的约束求解器; Choco,ECLiPSe,Gecode和奴才。为了评估设计决策的影响,对五个问题类n-Queens、Golomb Ruler、Magic Square、Social Golfers和Balanced Incomplete Block Design的实例进行建模,并使用每个求解器进行求解。实验的结果并不意味着给出求解器的性能的指示,而是调查算法和数据结构的选择有什么影响。设计决策的影响的分析集中在不同的方式的存储管理,行为与不断增加的问题的大小,和特定类型的变量的专门算法。它还简要考虑了其他不太重要的决定。

英文摘要:

This paper presents an evaluation of the design decisions made in four state-of-the-art constraint solvers; Choco, ECLiPSe, Gecode, and Minion. To assess the impact of design decisions, instances of the five problem classes n-Queens, Golomb Ruler, Magic Square, Social Golfers, and Balanced Incomplete Block Design are modelled and solved with each solver. The results of the experiments are not meant to give an indication of the performance of a solver, but rather investigate what influence the choice of algorithms and data structures has. The analysis of the impact of the design decisions focuses on the different ways of memory management, behaviour with increasing problem size, and specialised algorithms for specific types of variables. It also briefly considers other, less significant decisions.
