Interface IloObjective

All Superinterfaces:

IloAddable

public interface IloObjective

extends IloAddable

This interface defines the API for objectives. An objective function is defined by an objective expression and an optimization sense. The objective sense is represented by IloObjectiveSense objects and can be IloObjectiveSense.Minimize or IloObjectiveSense.Maximize.

Both the objective sense and expression can be queried and reset. In addition to this, the CPLEX class IloMPModeler provides methods for manipulating linear objective expressions through its methods setLinearCoef() and setLinearCoefs(). IloMPModeler is available to users of ILOG CPLEX.
