What's that Game that predicts your choices?


I remember finding a kind of game on HN in which the player could press either the right or the left arrow button on the keyboard and the application would learn to predict the next move quite quickly.

Does anyone remember it's name, or better even, a URL?

Thanks!

I believe it's called the "Aaronson Oracle". There are at least a couple implementations:

Not what OP is looking for (which has been answered), but 20Q is uncannily good at figuring out what you are thinking about.

As a bonus, it still has a fantastic mid-2000s web design. "The neural-net on the internet!"

Not exactly what you're looking for, but something similar and quite bluffing regarding choice prediction : https://en.akinator.com/game

I made my own some time ago: https://www.strandmark.net/prediction.html

On that page, I seem to mention that the original was "The Mindreader Applet." Don't know if that's true, but since it is/was an Applet, at least it isn't recent.

The first time I was exposed to such a program it was an AWK or gawk program, I think it was called "mind reader" or "mindreader" but I am unsure of it since I am unable to find it now.

EDIT: Ah here it is! The original was apparently by Shannon himself! https://literateprograms.org/mind_reading_machine__awk_.html

EDIT 2: apparently even older as he references Von Neumann, Morgenstern and even Edgar Allen Poe

no clue why its getting called Aaronsons Oracle...

I am unable to locate the memo for download but it appears to be collected in this book: http://neilsloane.com/doc/shannon.html

Kind of tongue in cheek and not at all what you're asking for but if you want a more complicated multiplayer version of this, try poker!
