Abstract
In this paper we study the parallel computational complexity of some m ethods for compressing data via textual substitution. We show that the Ziv-Lempel algorithm and two standard variations are P-complete. Henc e an efficient parallelization of these algorithms is not possible unl ess P = NC.
