Interface IIntegerPBSolver

All Superinterfaces:

IPBSolver, IProblem, ISolver, RandomAccessModel, Serializable

All Known Implementing Classes:

IntegerPBSolverDecorator, ManyCoreIntegerPB, SumLeximinDecompositionOWAOptimizer

public interface IIntegerPBSolver
extends IPBSolver

A PBSolver which implements this interface must be able to handle bounded positive integer variables. It defines PB constraints adding methods which are composed of a boolean part, and an integer part. Each part is made of a variable vector and a weight vector.
