Example 1 with IncompleteMultiVariableConstraint

use of com.sri.ai.grinder.core.constraint.IncompleteMultiVariableConstraint in project aic-expresso by aic-sri-international.

the class SGDPLLTTester method testIncompleteMultiVariableConstraints.

/**
 * Given a theory and a number <code>n</code> of multi-variable constraint tests,
 * generates <code>n</code> formulas in the theory
 * and see if those detected as unsatisfiable by the corresponding incomplete solver
 * are indeed unsatisfiable (checked by brute force).
 * Note that we do not test if all unsatisfiable formulas are detected as such, because the solver is assumed to be incomplete.
 * Throws an {@link Error} with the failure description if a test fails.
 * @param theoryTestingSupport
 * @param numberOfTests
 * @param maxNumberOfLiterals
