minisat - 1:2.2.1-5+b3 main

Despite the NP completeness of the satisfiability 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.
.
MiniSat is a minimalistic, open-source SAT solver, developed to help
researchers and developers alike to get started on SAT. Winning all the
industrial categories of the SAT 2005 competition, MiniSat is a good starting
