XPRSaddnames
XPRSaddnames |
Purpose
When a model is loaded, the rows, columns, sets, piecewise linear and general constraints of the model may not have
names associated with them. This may not be important as the rows, columns, sets, piecewise linear and general constraints can be referred to by their sequence numbers. However, if you wish row, column, set, piecewise linear and general constraint names to appear in the ASCII solutions files, the names for a range of rows/columns/... can be added with
XPRSaddnames.
Synopsis
int XPRS_CC XPRSaddnames(XPRSprob prob, int type, const char cnames[], int first, int last);
Arguments
|
prob
|
The current problem.
|
||||||||||
|
type
|
|
||||||||||
|
cnames
|
Character buffer containing the null-terminated string names.
|
||||||||||
|
first
|
Start of the range of rows, columns, sets, piecewise linear or general constraints.
|
||||||||||
|
last
|
End of the range of rows, columns, sets, piecewise linear of general constraints.

Example
Add variable names (
a and
b), objective function (
profit) and constraint names (
first and
second) to a problem:
char rnames[] = "profit\0first\0second" char cnames[] = "a\0b"; ... XPRSaddnames(prob,1,rnames,0,nrow-1); XPRSaddnames(prob,2,cnames,0,ncol-1);
