default_basis

Sets the starting base to an all slack basis (the default simplex starting basis).

void default_basis(lprec *lp);

Return Value

None

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 default_basis function sets the starting base to an all slack basis (the default simplex starting basis).

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);
  }

  /* Model created */

  default_basis(lp);

  delete_lp(lp);

  return(0);
}
