Retrieve small exact D-, A-, G-, and IV-Optimal designs generated by a genetic algorithm. These designs are catalogued by Borkowski (2003).

1 | ```
Borkowski2003(criterion, k, N)
``` |

`criterion` |
Only optimal criteria "D", "A", "G", and "IV" are available now. |

`k` |
The number of factor, k = 2 and 3 |

`N` |
The number of design points |

`Borkowski2003`

is called to generate the data frame of the design matrix of exact optimal designs.
