Interface IloMPModeler

All Superinterfaces:

All Known Implementing Classes:

IloCplex

public interface IloMPModeler

extends IloModeler

IloMPModeler is an extension of the IloModeler modeling interface for Mathematical Programing.

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. This interface is implemented by the IloCplex optimizer class.

Method Detail

delete

public void delete(ilog.concert.IloCopyable obj)
            throws IloException

Deletes an object from a model.

After calling this method, the modeling object obj is no longer in the model. If the modeling object is referenced multiple times in a model, for example, a variable used by multiple constraints, it is removed from all places. When you delete a variable from a model, it is removed from all the other modeling objects in the model. Modeling variable objects are not of type IloAddable, so the type of the removed object is IloCopyable, a common base interface of both IloAddable and IloNumVar.

Parameters:

obj - The modeling object to be deleted from the invoking IloModel.

IloException

delete

public void delete(ilog.concert.IloCopyable[] obj)
            throws IloException

Deletes the modeling objects in an array obj from the invoking IloModel. After calling this method, the deleted objects are no longer in the model. If a modeling object is referenced multiple times in a model, for example, a variable used by multiple constraints, it is removed from all places. When you delete variables from a model, they are removed from all other modeling objects in the model.

Parameters:

obj - The array of modeling objects to be deleted from the invoking IloModel

IloException

delete

public void delete(ilog.concert.IloCopyable[] obj,
                   int start,
                   int num)
            throws IloException

Deletes the modeling objects in obj[start] through obj[start+num-1] from a model. Modeling objects obj[start] through obj[start+num-1] are deleted from the invoking IloModel. After calling this method, the deleted objects will no longer be in the model. If a modeling object is referenced multiple times in a model, e.g. a variable used by multiple constraints, it is removed from all places. Thus, when deleting variables from a model, they are removed from all other modeling objects in the model.

Parameters:

obj - An array containing the modeling objects to be deleted from the invoking IloModel.

start - The index of the first modeling object in obj to be deleted from the invoking IloModel.

num - The number of modeling objects in obj to be deleted from the invoking IloModel.

                                        throws IloException

Creates an expression node that represents a continuous or discontinuous piecewise linear function.

The piecewise linear function is evaluated at expr and is defined by the remaining parameters. The array points contains breakpoints such that points[i-1] is less than or equal to points[i]. The array slopes contains the value of the slope for each piece defined by the breakpoints. The slope of the function for values less than points[0] is slopes[0]. Similarly, slopes[i] specifies the slope between points[i-1] and points[i]. Thus the array slope must have one more element than the array points.

By setting points[i-1] == points[i], you can represent a discontinuous piecewise linear function. In this case, the function will make a step of size slopes[i-1] at position points[i].

The values a and fa define the x and y coordinates of one point of the piecewise linear function. This point is referred to as the anchor point.

Parameters:

expr - An expression indicating where to evaluate the piecewise linear function.

points - An array of breakpoints for the piecewise linear function.

slopes - An array of slopes for the piecewise linear function.

a - First coordinate of the anchor point of the piecewise linear function.

fa - Second coordinate of the anchor point of the piecewise linear function.

Returns:

A piecewise linear function of expr.

Creates an expression node to represent a continuous or discontinuous piecewise linear function.

The piecewise linear function is evaluated at expr and is defined by the remaining parameters. The array points contains breakpoints such that points[i-1] is less than or equal to points[i]. Only num elements starting with element startPoints are considered. The array slopes contains the slope for each piece defined by the breakpoints. Only num+1 elements starting with element startSlopes are considered. The element slopes[startSlopes] specifies the slope of the piecewise linear function for values less than points[startPoints], and slopes[startSlopes+num] specifies the slope of the piecewise linear function for values greater than points[startPoints+num-1]. For elements in between, slopes[startSlopes+i] specifies the slope between points[startPoints+i-1] and points[startPoints+i].

By selecting points[startPoints+i-1] == points[startPoints+i], you can represent a discontinuous piecewise linear function. At points[startPoints+i], it will make a step of size slope[startSlopes+i-1].

The values a and fa define the x and y coordinates of one point of the piecewise linear function. This point is referred to as the anchor point.

Parameters:

expr - An expression indicating where to evaluate the piecewise linear function.

points - An array containing breakpoints that define the piecewise linear function.

startPoints - An integer indicating the first element in array points to use for the definition of the breakpoints of the piecewise linear function.

num - The number of breakpoint to use from array points. Thus num+1 elements of array slopes are used.

slopes - An array containing the slope values that define the piecewise linear function.

startSlopes - The first element in array slopes to use for the definition of the slopes of the piecewise linear function.

a - The first coordinate of the anchor point of the piecewise linear function.

fa - The second coordinate of the anchor point of the piecewise linear function.

Returns:

A piecewise linear function of expr.

Creates an IloColumnArray object suitable for adding new variables to an IloLPMatrix as columns. The procedure is as follows: You create an IloColumnArray from an IloLPMatrix by calling columnArray() with the list of non-zeros for each new column given in arrays ind and val. You optionally combine this column array with IloColumnArray objects created for other modeling objects. Then you create an array of variables by passing the so constructed IloColumnArray object to the appropriate method of the IloMPModeler you use.

Parameters:

lp - The IloLPMatrix object for which to create the new column array term.

num - The size of the column array term to create or, equivalently, the number of elements in ind and val to use.

ind - An array of arrays of row indices of the non-zeros for each of the new columns. Indices may not occur multiple times within one column, and they must be in the range 0 through lp.getNcols()-1.

val - An array of arrays of values of the non-zeros for each of the new columns.

Returns:

An IloColumnArray object suitable for creating new columns in the LP matrix lp as specified by parameters ind and val.
