Method Detail

addPseudoBoolean

public IConstr addPseudoBoolean(IVecInt literals,
                                IVec<java.math.BigInteger> coeffs,
                                boolean moreThan,
                                java.math.BigInteger degree)
                         throws ContradictionException
Description copied from interface: IPBSolver
Create a Pseudo-Boolean constraint of the type "at least n of those literals must be satisfied"

Specified by:
addPseudoBoolean in interface IPBSolver
Overrides:
addPseudoBoolean in class PBSolver<ILits>
Parameters:
literals - a set of literals. The vector can be reused since the solver is not supposed to keep a reference to that vector.
coeffs - the coefficients of the literals. The vector can be reused since the solver is not supposed to keep a reference to that vector.
moreThan - true if it is a constraint >= degree
degree - the degree of the cardinality constraint
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 the constraint is falsified after unit propagation

ISolver.removeConstr(IConstr)

toString

public java.lang.String toString(java.lang.String prefix)
Specified by:
toString in interface ISolver
Overrides:
toString in class PBSolverCP<ILits>
