Interface IloModeler

All Known Subinterfaces:

IloMPModeler

public interface IloModeler

extends IloModel

Interface for basic modeling. IloModeler defines an interface for building basic optimization models. This interface contains methods for constructing variables, basic constraints, and objective function objects. It is typically implemented by such optimizer classes as IloCplex, available in ILOG CPLEX or IloSolverFactory, available in ILOG JSolver. By using this interface rather than the actual implementation class, you can create optimization models that can be solved by any optimizer implementing the interface.
This interface is an extension of the IloModel interface, and allows you to add modeling objects (instances of IloAddable) to an IloModeler object. For an optimizer implementing this interface, the model built corresponds to the model the optimizer will solve using its solve() method.
Note that there are two interfaces derived from IloModeler: IloCPModeler, available in ILOG JSolver and IloMPModeler, available in ILOG CPLEX. IloCPModeler defines the API for constraint-based engines. (An engine is an object whose function is to manipulate models that include variables and constraints.) IloMPModeler is a modeling interface for Mathematical Programming. It adds support for several new modeling object interfaces, including LP matrices, semi-continuous variables, and special ordered sets (SOSs). It extends the functionality of IloModeler to column-wise modeling and supports modification of variable types and expressions of ranged constraints and objective functions.
