Method Detail

addControlableClause

public IConstr addControlableClause(IVecInt literals,
                           int desc)
                             throws ContradictionException

Throws:

ContradictionException

addNonControlableClause

public IConstr addNonControlableClause(IVecInt literals)
                                throws ContradictionException

Throws:

ContradictionException

addClause

public IConstr addClause(IVecInt literals,
                int desc)
                  throws ContradictionException

Specified by:

addClause in interface IGroupSolver

Parameters:

literals - a clause

desc - the level of the clause set

Returns:

on object representing that clause in the solver.

Throws:

ContradictionException

getAddedVars

public Collection<Integer> getAddedVars()

Specified by:

getAddedVars in class AbstractClauseSelectorSolver<T extends ISolver>

model

public int[] model()

Description copied from interface: IProblem

Provide a model (if any) for a satisfiable formula. That method should be called AFTER isSatisfiable() or isSatisfiable(IVecInt) if the formula is satisfiable. Else an exception UnsupportedOperationException is launched.

Specified by:

model in interface IProblem

Overrides:

model in class SolverDecorator<T extends ISolver>

Returns:

a model of the formula as an array of literals to satisfy.

See Also:

IProblem.isSatisfiable(), IProblem.isSatisfiable(IVecInt)

getVarToHighLevel

public Map<Integer,Integer> getVarToHighLevel()
