  • Method Details

    • satisfiable

      public boolean satisfiable(int[] assumptions)
      Specified by:
      satisfiable in interface SatSolver
    • witness

      public boolean[] witness(int[] literals, int[] assumptions)
      Specified by:
      witness in interface SatSolver
    • 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!

      Specified by:
      add in interface SatSolver
      clause - the clause to add
    • 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.
