int get_improve(lprec *lp);

Return Value

get_improve returns the iterative improvement level. Can by any of the following values:

IMPROVE_NONE (0)	improve none
IMPROVE_FTRAN (1)	improve FTRAN
IMPROVE_BTRAN (2)	improve BTRAN
IMPROVE_SOLVE (3)	improve FTRAN + BTRAN
IMPROVE_INVERSE (4)	Triggers automatic inverse accuracy control in the dual simplex, and when an error gap is exceeded the basis is reinverted

Parameters

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

improve

Remarks

The get_improve function returns the iterative improvement level.
The default is IMPROVE_NONE.

Example

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

int main(void)
{
  lprec *lp;
  int improve;

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

  improve = get_improve(lp); /* Will return 0 */

  delete_lp(lp);
  return(0);
}
