Abstract

We describe a SAT-solver, BerkMin, that inherits suchfeatures of GRASP, SATO, and Chaff as clause recording,fast BCP, restarts, and conflict clause "aging". At thesame time BerkMin introduces a new decision makingprocedure and a new method of clause databasemanagement. We experimentally compare BerkMin withChaff, the leader among SAT-solvers used in the EDAdomain. Experiments show that our solver is more robustthan Chaff. BerkMin solved all the instances we used inexperiments including very large CNFs from amicroprocessor verification benchmark suite. On the otherhand, Chaff was not able to complete some instances evenwith the timeout limit of 16 hours.
