trace

TRUE or FALSE. Print or do not print.

Remarks

The set_trace function sets a flag if pivot selection must be printed while solving. This function is mend for debugging purposes. The default is not to print (FALSE).

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_trace(lp, TRUE);

  delete_lp(lp);
