摘要

在并行计算环境下,提出了一种基于创建析取范式子句(DNF)和轮询负载平衡算法的求给定集合幂集的方法。给定一个大小为n的问题,DNF算法和轮询负载平衡,我们将在O[n /| n/|次迭代中并发地计算整个功率集。对于计算机科学教科书或互联网搜索中发现的计算幂集的顺序算法来说,迭代次数的减少明显小于O(2^n)。轮询负载平衡算法为规模为n的幂集问题分配了小于|n/2|个处理器。本文给出了规模较大的幂集问题的算例。

Efficiently Computing the Power Set in a Parallel Environment
We develop an approach to find the power set of a given set based on creating disjunctive normal form clauses (DNF) and a round robin load balancing algorithm in a parallel computing environment. Given a problem of size n, the DNF algorithms and the round robin load balance, we will compute the entire power set in O[n / |n/| iterations, concurrently. This reduction in iterations is significantly less than O(2^n) for the sequential algorithms that compute the power set found in Computer Science text books or found in internet searches. The round robin load balance algorithm assigns less than |n/2| processors to the power set problem of size n. This paper gives examples to the power set problem for a relatively large set.
