ChgObjN Method

Modifies one or more coefficients of an objective function in a multi-objective problem. If the objective already exists, any coefficients not present in the colind and objcoef arrays will unchanged. If the objective does not exist, it will be added to the problem.

Namespace:  Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 45.01.02+1f9fd7ff9a8620394fec1839699751312debed40
Syntax
C# 
public void ChgObjN(
	int objidx,
	int ncols,
	int[] colind,
	double[] objcoef
)

Parameters

objidx   Int32
Index of the objective function to add or modify.
ncols   Int32
Number of objective function coefficient elements to change.
colind   Int32
Integer array of length ncols containing the indices of the columns whose objective coefficients will change. An index of -1 indicates that the fixed part of the objective function on the right hand side should change.
objcoef   Double
Double array of length ncols giving the new objective function coefficients.
