Coprocessor

Coprocessor 2.0 – A Flexible CNF Simplifier (Tool Presentation). This paper presents the CNF simplifier Coprocessor 2.0, an extension of Coprocessor [1]. It implements almost all currently known simplification techniques in a modular way and provides access to each single technique to execute them independently. Disabling preprocessing for a set of variables is also possible and enables to apply simplifications also for incremental SAT solving. Experiments show that Coprocessor 2.0 performs better than its predecessor or SatElite[
