Note that no effort has been made to `optimize' most of the algorithms used in the programs below. The algorithms work well, but by no means should be used as a basis for an implementation. All these programs are free to use for academic and personal purposes only. Use them at your own discretion.<br>(<a href="https://roland.iwasno.net/links/?pcYKbg">Permalink</a>)
