public AbstractPBDataStructureFactory()

Method Detail

createClause

public Constr createClause(IVecInt literals)
                    throws ContradictionException

Specified by:

createClause in interface DataStructureFactory<ILits>

Parameters:

literals - a set of literals using Dimacs format (signed non null integers).

Returns:

null if the constraint is a tautology.

Throws:

ContradictionException - the constraint is trivially unsatisfiable.

createUnregisteredClause

public Constr createUnregisteredClause(IVecInt literals)

Specified by:

createUnregisteredClause in interface DataStructureFactory<ILits>

createCardinalityConstraint

public Constr createCardinalityConstraint(IVecInt literals,
                                          int degree)
                                   throws ContradictionException

Specified by:

createCardinalityConstraint in interface DataStructureFactory<ILits>

Overrides:

createCardinalityConstraint in class AbstractDataStructureFactory<ILits>

Throws:

ContradictionException

createPseudoBooleanConstraint
