set_BFP

Set basis factorization package.

unsigned char set_BFP(lprec *lp, char *filename);

Return Value

set_BFP returns TRUE if the call has succeeded, else FALSE.

Parameters

Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI

filename

The name of the BFP package. Currently following BFPs are implemented:

"bfp_etaPFI"	original lp_solve product form of the inverse.
"bfp_LUSOL"	LU decomposition.
"bfp_GLPK"	GLPK LU decomposition.
NULL	The default BFP package.

However the user can also build his own BFP packages ...

Remarks

The set_BFP function sets the basis factorization package (BFP). See Basis Factorization Packages for a complete description on BFPs.

Example

#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"

int main(void)
{
  lprec *lp;

  /* Create a new LP model */
  lp = make_lp(0, 0);
  if(lp == NULL) {
    fprintf(stderr, "Unable to create new LP model\n");
    return(1);
  }

  set_BFP(lp, "bfp_LUSOL");

  delete_lp(lp);
  return(0);
}
