A Parallel Algorithm for the Knapsack Problem

View publication

Abstract

A time-memory-processor tradeoff for the knapsack problem is proposed. While an exhaustive search over all possible solutions of an n-component knapsack requires T = 0(2n) running time, our parallel algorithm solves the problem in 0(2n/2) operations and requires only 0(2n/6) processors and memory cells. It is an improvement over previous time-memory-processor tradeoffs, being the only one which outperforms the Cm Cs = 2ncurve. Cm is the cost of the machine, i.e., the number of its processors and memory cells, and Cs is the cost per solution, which is the product of the machine cost by the running time. © 1984 IEEE
