Returns a flag if pivot selection must be printed while solving.

Return Value

is_trace returns TRUE or FALSE. Print or do not print.

Parameters

Pointer to previously created lp model. See return value of make_lp, read_lp, read_LP, read_lpt, read_LPT, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI

Remarks

The is_trace function returns 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;
  unsigned char trace;

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

  trace = is_trace(lp); /* Will return FALSE */

  delete_lp(lp);
  return(0);
}
