Webb10 nov. 2024 · A SAT solver is an algorithm for establishing satisfiability. It takes the Boolean logic formula as input and returns SAT if it finds a combination of variables that can satisfy it or UNSAT if it can demonstrate that no such combination exists. Webb25 apr. 2015 · The solver class Minisat is used to solve the formula. Note: the Minisat class creates two temporary files, so it needs write access to the system’s temporary directory The returned solution can be checked by reading the “success” boolean flag. Then, the solution can be queried for variable assignments by using it like a dictionary.
