SAT solver with proof and core support
Despite the NP completeness of the satisfiabilty problem of Boolean formulas (SAT), SAT solvers are often able to decide this problem in a reasonable time frame. As all other NP complete problems are reducible to SAT, the solvers have become a general purpose tool for this class of problems.
PicoSAT is a SAT solver that turned out to be faster on industrial instances than MiniSAT 2.0 and also can generate proofs and cores in memory.
