Hi guys i bought this thing called 20Q about a year ago and found a website thats the same thing. Check it out.

http://www.20q.net/

I was quite impressed anyway.

Jim

took it 23 questions to get "deck of cards"
slightly more fun than i was expecting

I had a 20Q for christmas... fascinating thing...

Reminded me of one of my first hand-keyed computer games, Animal vegetable mineral on the ZX Spectrum.

Imagine a PDA with a massive database. You could use it to "scientifically" read practically any thought the spec cared to have.

Just add voice recognition and you're off!

I was thinking windsurfer but it got surfboard in 4 guesses which is close enough for me.

I beat it, with Terminator (the movie character).

I'll be back...

I meant 24 guesses

I won with Derren Brown

I won with Doctor Who but mainly because of things like yes to him having dark hair where other answers had said no. The first three suggestions were Starsky & Hutch, The Hulk and Erik Estrada !

It's an interesting application in as much as it works in quite the opposite way to some of what I perceive to be mentalism techniques.

20Q asks questions which create the greatest partition in the answer space, even if they have a negative answer, where as most mind reading type scripts are oriented towards the positive answer.

I think that's because 20Q uses a depth first tree search.

I'm not sure that data is store in a tree at all. I think it has a number of properties per object and performs a fuzzy binary best-first type search on the data. If that makes sense

It does. There's also a product called 20Q that uses a neural net.
