add
public void add(int[] clause) Description copied from interface:SatSolver
Adds the given clause to the SAT solver state.Note that contrary to DIMACS format, a trailing '0' is not required!
-
newVar
public int newVar()Description copied from interface:SatSolver
Creates and returns the integer representation of a fresh propositional variable.It is necessary to only use variables returned by this method, since some solvers require to first allocate and maintain a data structure of the variables before they can be used in clauses. Hence, using integers not returned by this method may work for some solvers, but not for others.
