A parallel time/hardware tradeoff T.H=O(2/sup n/2/) for the knapsack problem

A parallel algorithm for solving the knapsack problem on a single-instruction, multiple-data machine with shared memory is presented. The shared memory allows concurrent reading while concurrent writing is forbidden. The knapsack problem is of size n, which the algorithm solves in time T=O(n*(2/sup n/2/)/sup epsilon /) when P=O((2/sup n/2/)/sup (1- epsilon )/), 0>
