get_max_level

Returns the deepest Branch-and-bound level of the last solution.

int get_max_level(lprec *lp);

Return Value

get_max_level returns the deepest Branch-and-bound level of the last solution.

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

Remarks

The get_max_level function returns the deepest Branch-and-bound level of the last solution.
Is only applicable if the model contains integer variables.

Example

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

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

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

  max_level = get_max_level(lp);

  delete_lp(lp);
  return(0);
}
