set_epsperturb

Specifies the value that is used as perturbation scalar for degenerative problems.

void set_epsperturb(lprec *lp, REAL epsperturb);

Return Value

set_epsperturb has no return value.

Parameters

lp

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

epsperturb

perturbation scalar.

Remarks

The default epsperturb value is 1e-5

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_epsperturb(lp, 1.0e-6); /* sets epsperturb to 1e-6 */

  delete_lp(lp);
  return(0);
}
