Fuzzy operators for Mathematica.
1.1q
Approximately 1.2 billion years ago, I created a set of fuzzy operators for the Derive computer algebra system, running on my HP-95LX pocket computer. It was the coolest thing since sliced bread.
I also ported it over to Mathematica 1.0 at the time (running on a Sun II in my office at Pixar).
I was doing a thing last week, now 25+ years later, where I needed to do Fuzzy Boolean operators, so I dug it out, cleaned it up and here we are. (It was on a tape cart ☞ floppy ☞ Syquest ☞ Zip Drive ☞ CD ROM ☞ DVD ROM ☞ Synology. Let's hear it for pack-rattery.)
Sadly, this is no replacement for the super cool FuzzyLogic Mathematica package (RIP).
It is simply the ten fuzzy boolean operators + a few things here and there that add to the fun. It implements the traditional 'Zadeh' operators, along with Yager and HyperbolicParaboloid variants, selectable with Method.
