get_total_nodes

Returns the total number of nodes processed in branch-and-bound.

int get_total_nodes(lprec *lp);

Return Value

get_total_nodes returns the total number of nodes processed in branch-and-bound of the last solution.

Parameters

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_total_nodes function returns the total number of nodes processed in branch-and-bound of the last solution.
Is only applicable if the model contains integer variables.

Example

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

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

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

  total_nodes = get_total_nodes(lp);

  delete_lp(lp);
  return(0);
}
