Method Summary

Modifier and Type	Method and Description
<T> T	allSat(ProverEnvironment.AllSatCallback<T> pCallback, List<BooleanFormula> pImportant) Get all satisfying assignments of the current environment with regards to a subset of terms, and create a region representing all those models.
List<BooleanFormula>	getUnsatCore() Get an unsat core.
boolean	isUnsatWithAssumptions(Collection<BooleanFormula> assumptions) Check whether the conjunction of all formulas on the stack together with the list of assumptions is satisfiable.
Optional<List<BooleanFormula>>	unsatCoreOverAssumptions(Collection<BooleanFormula> pAssumptions) Returns an UNSAT core (if it exists, otherwise Optional.empty()), over the chosen assumptions.

Method Detail

isUnsatWithAssumptions

public boolean isUnsatWithAssumptions(Collection<BooleanFormula> assumptions)
                               throws SolverException,
                                      InterruptedException

Description copied from interface: ProverEnvironment

Check whether the conjunction of all formulas on the stack together with the list of assumptions is satisfiable.

Specified by:

isUnsatWithAssumptions in interface ProverEnvironment

Parameters:

assumptions - A list of literals.

Throws:

SolverException

InterruptedException

getUnsatCore

public List<BooleanFormula> getUnsatCore()

Description copied from interface: ProverEnvironment

Get an unsat core. This should be called only immediately after an BasicProverEnvironment.isUnsat() call that returned false.

Specified by:

getUnsatCore in interface ProverEnvironment

allSat

public <T> T allSat(ProverEnvironment.AllSatCallback<T> pCallback,
                    List<BooleanFormula> pImportant)
             throws InterruptedException,
                    SolverException

Description copied from interface: ProverEnvironment

Get all satisfying assignments of the current environment with regards to a subset of terms, and create a region representing all those models.

Specified by:

allSat in interface ProverEnvironment

pImportant - A set of variables appearing in f. Only these variables will appear in the region.

Returns:

A region representing all satisfying models of the formula.

Throws:

InterruptedException

SolverException

unsatCoreOverAssumptions

public Optional<List<BooleanFormula>> unsatCoreOverAssumptions(Collection<BooleanFormula> pAssumptions)
                                                        throws SolverException,
                                                               InterruptedException

Description copied from interface: ProverEnvironment

Returns an UNSAT core (if it exists, otherwise Optional.empty()), over the chosen assumptions. Does NOT require the SolverContext.ProverOptions.GENERATE_UNSAT_CORE option to work.

Specified by:

unsatCoreOverAssumptions in interface ProverEnvironment

Parameters:

pAssumptions - Selected assumptions

Returns:

Empty optional if the constraints with assumptions are satisfiable, subset of assumptions which is unsatisfiable with the original constraints otherwise.

Throws:

SolverException

InterruptedException
