addAtMost

IConstr addAtMost(IVecInt literals,
                  IVecInt coeffs,
                  int degree)
           throws ContradictionException

Description copied from interface: IPBSolver

Create a pseudo boolean constraint of the type "at most".

Specified by:

addAtMost in interface IPBSolver

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.

degree - the degree of the pseudo-boolean constraint

Returns:

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

Throws:

ContradictionException - iff the constraint is found trivially unsat.
