de.tilman_neumann.jml.factor.base.congruence.CongruenceCollectorParallel

public class CongruenceCollectorParallel
extends CongruenceCollector

Collects smooth and partial congruences, and assembles partials to smooth congruences on-the-fly. Partials may have any number of large factors. This implementation is appropriate for multi-threaded congruence generation.
