In contrast to related tools like MathSAT, {ICS,} or {CVC,} our tool exploits all of the various optimizations that arise naturally in the bounded model checking context, e.g. isomorphic replication of learned conflict clauses or tailored decision strategies, and extends them to the hybrid domain. We demonstrate that those optimizations are crucial to the performance of the tool." }
