Abstract

This paper studies the following question: given an instance of the propositional satisfiability problem, a randomized satisfiability solver, and a cluster of n computers, what is the best way to use the computers to solve the instance? Two approaches, simple distribution and search space partitioning as well as their combinations are investigated both analytically and empirically. It is shown that the results depend heavily on the type of the problem (unsatisfiable, satisfiable with few solutions, and satisfiable with many solutions) as well as on how good the search space partitioning function is. In addition, the behavior of a real search space partitioning function is evaluated in the same framework. The results suggest that in practice one should combine the simple distribution and search space partitioning approaches.

随机搜索的搜索空间划分
本文研究的问题是:给定一个命题可满足性问题的实例,一个随机可满足性解算器和一个n台计算机组成的集群,使用计算机解决该实例的最佳方法是什么?对简单分布和搜索空间划分两种方法及其组合进行了分析和实证研究。研究表明,结果在很大程度上取决于问题的类型(不可满足、解少可满足和解多可满足)以及搜索空间划分函数的好坏。此外,在相同的框架中对实际搜索空间划分函数的行为进行了评估。结果表明,在实际应用中,应将简单分布和搜索空间划分相结合。
