number one: pick your card, then take a look at the others before you click
The sick thing is he has a page with a hundred or so people saying how amazed they are and giving explanations like that they think the monitor can read their eye movements. Sad.
I couldn't get the second link to work.
The third one is interesting if poorly coded. I got 50.98% after 254 guesses. You can intuit what patterns it is ascribing to your behavior and then counter them. I have heard of similar coding contests. There is one where you develop a code to win at rock-paper-scissors. If your code is able to generate truly random guesses you will win 50% of the time, but if you can figure out how the other code is generating answers you can come close to 100%. One of the recent winners used, I think, 7th level Cicilian logic (think Princess bride). Since I was able to get about 50%, this code sucks.

The first two are very easy.
The second is tricky.. It doesn't use tricks like the first two, but it does use a 'trick' so to speak.. I could probably make a program that did the same thing, or perhaps even one that could beat his program.
(It's similar to a rock-paper-scissors/roshambo competition, random play gives 50%, a strategy can give higher results if the other also uses a strategy)

I think I submitted at ?:24 and oyu were finished editing at ?:35
Anyway.. if you have two programs running against each other, and one is using random guesses you can't get much better than 50%, and the only by chance..
The only way to really beat another competitor is if he uses a strategy you recognize and can beat.
And once you have a significant lead, you can use random guesses to keep on top (though I think it is disallowed to use a random guessing program)
In any case, 50% might still be good.
I lost once, and beat the program once.. The second time I tricked it early on, then used a random number generator to keep on top.

Hm, what exactly do you mean by "the second [...] doesn't use tricks like the first two"?
I guess you mean the second link. It took me a little while to see the pattern, so to speak.
Or maybe you mean the third link. Well, I won't spend my time figuring out how that one works.

hmm.. yes, I meant third..
the second is easy once you see the pattern, think multiple of 9..

For the predictive algorithm, if you input the first 250 binary digits of pi it scores no more than 48%.

Funny, I tried the very first one but it doesn't seem to work at all. It has /never/ removed the card I chose.

Is that what the entire trick is? Always remove "Black Jack" and watch the person waste 45 minutes trying to figure out why it doesn't work?

I don't know. I've tried Cliff's experiment at two websites with my web proxy and without it, yet it always removes the same card.

Wow. That trick really sucks. I've got it now. I just wasn't paying attention to the shape at all.

What, you were picking the black jack rather than the jack of clubs for example?

The way the "remove your card" trick works, as explained at www .snopes.com, is that NONE of the cards in the first set of six appear in the second set of five; only cards that appear similar. Since people will only concentrate on remembering the one card they chose, they don't notice that the other cards from the first set aren't there either.
By the way, hide tags won't hide imbedded links...

hello world
about http://intelligence.sergi5.com/
the original idea was to beat the human brain random generator and not another program. as you can see in the statistic page, the delay between each key is important and if typed very quickly, scores are very high.

Er, how is that supposed to work?
I tried typing 0's and 1's in the long input field, but it just says "You have no tryed [sic] to play!" and "You have not typed enough keys!".
Am I supposed to type the numbers one-by-one? And is there another way to play than to click the "view..." button?
Oh, wait. Is this some queer javascript stuff? Then it's probably my browser again...
I think there's room for improvement regarding the presentation.

Wow! Upon closing the window, I got this in a new window:
Quote:
You have played during:1059740955 seconds
Number of key pressed:9
Average time by key pressed:117748995.0000000000seconds
The computer have predicted:undefined% of your thoughts.

That's the way to guarantee a win: Consider undefined as a win and don't define anything!

I sent Cliff this email:
Your ESP experiment is tantalizing! I was so astounded the first 6 times I tried it that I had to figure out how it worked. So I tried the experiment again this way: open the page with the five cards and take a screenshot (without looking at the cards at all). Now open the next page BEFORE DECIDING ON A CARD. Now look at the screenshot and pick one of the five cards, and it has been removed! To be even more sure, try picking another one, and IT HAS BEEN REMOVED TOO. No matter which of the five you pick, THEY HAVE ALL BEEN REMOVED AS SOON AS YOU PICK THEM! But I know how you do it. Because of the law of causality, your computer can't predict my actions, but YOU WAIT UNTIL THE SECOND PAGE IS DISPLAYED TO COLLAPSE THE QUANTUM STATE OF THE OBSERVER/OBSERVATION! -- James Fingas

I beat the "intelligent" computer without using a random number generator. You have to play for at least 205 digits. You just have to have a good idea of what it thinks you're going to do. That being said, I didn't beat it by much... I wonder how hard it would be to write a computer program that could beat it by a large margin?
