Using BCL with the Optimizer library

BCL provides both modeling and basic optimization functions, which correspond to the functionality of Xpress Mosel, or of the functions of the Xpress Optimizer library in `Console Mode', respectively. However, if the user wishes to access the more advanced features of the Optimizer, obtain additional information, or change algorithm settings, the relevant Optimizer library functions have to be used directly.

The following sections explain in more detail how to use Optimizer library functions within a BCL program. The first section lists those functions which are compatible with BCL. It is followed by some general remarks about initialization, loading the matrix and the use of indices. The last section contains some typical examples for the use of BCL-compatible Optimizer functions in BCL programs.

Important: If a program uses Optimizer library functions the Optimizer header file has to be included in addition to the BCL header file. That is, the first lines of the program should contain the following:

#include "xprb.h"
#include "xprs.h"
