Abstract

Given an off-line sequence S of n set-manipulation operations, we investigate the parallel complexity of evaluating S (i.e., finding the response to every operation in S and returning the resulting set). We show that the problem of evaluating S is in NC for various combinations of common set-manipulation operations. Once we establish membership in NC (or, if membership in NC is obvious), we develop techniques for improving the time and/or processor complexity.
