Method Detail

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

createClause

public Constr createClause(IVecInt literals)
                    throws ContradictionException

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)

createLits

protected ILits createLits()

Specified by:

createLits in class AbstractDataStructureFactory<ILits>
