get_break_at_value

Returns the value at which the branch-and-bound algorithm stops when the object value is better than this value.

REAL get_break_at_value(lprec *lp);

Return Value

get_break_at_value returns the value to break on.

Parameters

lp

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

Remarks

The get_break_at_value function returns the value at which the branch-and-bound algorithm stops when the object value is better than this value. Stopping at a given object value can be useful if you are only interested for a solution that has an object value which is at least a given value, but not necessarily (and most probably) the most optimal solution.
The default value is (-) infinity.

Example

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

int main(void)
{
  lprec *lp;
  REAL break_at_value;

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

  break_at_value = get_break_at_value(lp); /* Will return -1e24 */

  delete_lp(lp);
  return(0);
}
