Method Detail

addControlableClause

public IConstr addControlableClause(IVecInt literals)
                             throws ContradictionException

Throws:

ContradictionException

addNonControlableClause

public IConstr addNonControlableClause(IVecInt literals)
                                throws ContradictionException

Throws:

ContradictionException

addClause

public IConstr addClause(IVecInt literals)
                  throws ContradictionException

Description copied from interface: ISolver

Create a clause from a set of literals The literals are represented by non null integers such that opposite literals a represented by opposite values. (classical Dimacs way of representing literals).

Specified by:

addClause in interface ISolver

Overrides:

addClause in class SolverDecorator<T extends ISolver>

Parameters:

literals - a set of literals

Returns:

a reference to the constraint added in the solver, to use in removeConstr().

Throws:

ContradictionException - iff the vector of literals is empty or if it contains only falsified literals after unit propagation

See Also:

ISolver.removeConstr(IConstr)

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)

getConstraints

public Collection<IConstr> getConstraints()

Since:

2.1

getAddedVars

public Collection<Integer> getAddedVars()

Specified by:

getLastConstr
