Satisfiability (SAT) solver for boolean variables

PicoSAT is a satisfiability (SAT) solver for boolean variables in boolean expressions. A SAT solver can determine if it is possible to find assignments to boolean variables that would make a given set of expressions true. If it's satisfiable, it can also show a set of assignments that make the expression true. Many problems can be broken down into a large SAT problem (perhaps with thousands of variables), so SAT solvers have a variety of uses.
