addPseudoBoolean

public IConstr addPseudoBoolean(IVecInt lits,
                                IVec<BigInteger> coeffs,
                                boolean moreThan,
                                BigInteger d)
                         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

Parameters:

lits - 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

d - 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
