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, copy_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);
}
