  • Method Details

    • eval

      public <T extends Formula> @Nullable T eval(T formula)
      Description copied from interface: Evaluator
      Evaluate a given formula substituting the values from the model and return it as formula.

      If a value is not relevant to the satisfiability result, the solver can choose either to insert an arbitrary value (e.g., the value 0 for the matching type) or just return null.

      The formula does not need to be a variable, we also allow complex expression. The solver will replace all symbols from the formula with their model values and then simplify the formula into a simple formula, e.g., consisting only of a numeral expression.

      Specified by:
      eval in interface Evaluator
      Parameters:
      formula - Input formula to be evaluated.
      Returns:
      evaluation of the given formula or null if the solver does not provide a better evaluation.

    • evaluate

      public @Nullable Object evaluate(Formula formula)
      Description copied from interface: Evaluator
      Evaluate a given formula substituting the values from the model.

      If a value is not relevant to the satisfiability result, the model can choose either an arbitrary value (e.g., the value 0 for the matching type) or just return null.

      The formula does not need to be a variable, we also allow complex expression.

      Specified by:
      evaluate in interface Evaluator
      Parameters:
      formula - Input formula
      Returns:
