is_maxim

Returns objective function direction.

unsigned char is_maxim(lprec *lp);

Return Value

is_maxim returns a boolean value indicating if the objective direction is maximize (TRUE) or minimize (FALSE).

Parameters

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

Remarks

The default of lp_solve is to minimize, except for read_lp, read_LP where the default is to maximize.

Example

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

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

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

  ret = is_maxim(lp); /* will return FALSE */

  delete_lp(lp);
  return(0);
}
