Example 1 with DefaultMultiVariableConstraint

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

the class SGDPLLTTester method testMultiVariableConstraints.

 * are indeed unsatisfiable (checked by brute force).
 * Throws an {@link Error} with the failure description if a test fails.
