10th aniversery of deep blue win: interesting news article

[Terry McCracken]

It's a foregone conclusion that Deep Blue wasn't very strong, clearly weaker than today's top engines, and that Kasparov could have played much better. Psychology definitely played a large role in that match.

"wasn't very strong" yet it blew away every program 10 years ago. Sort of a "self-contradiction" IMHO. It was far from "not very strong"...

Maybe strong a decade ago, but it certainly isn't "very strong" today. You can use today's engines to see that they find Deep Blue's move in a fraction of the time on ordinary hardware, and they can even find stronger moves.

Too bad we can't put that to the test...the results might surprise you!

Who says we can't put that to the test? Even in Deep Blue's prime there were hundreds of computer systems more powerful than it. Today there are computer systems that are billlions of times more powerful than Deep Blue was.

Hydra, which calculates just as fast as Deep Blue did, is arguably stronger, and look how well it has been doing lately against the top engines (not well at all).

If you have a top chess engine, you can analyse all of Deep Blue's moves and you'll see that the engine finds the moves quicker than Deep Blue does, and can even produce stronger moves. Logically, today's top engines are clearly stronger than Deep Blue was.

What a load!

First, there are NOT computers billions of times faster than Deep Blue, and there may not be for a long time to come.

Hydra can't match Deep Blues speed. I've no idea where you're getting your information from....the top of your head, I suppose?

Hydra is in the closet so you can't test it, and it's playing no one or no machine either as of late.

Some engines have found Deep Blues moves, not faster than Deep Blue. How would you know if it found stronger moves than Deep Blue?

Sometimes I don't know why I bother answering, it doesn't do any good, and facts seem to escape most people

You want facts? Here's some facts. The Deep Blue version that beat Garry Kasparov in 1997 only evaluated 200 million positions per second (Hydra is also able to evaluate 200 million positions per second), and had a calculating speed of 11.38 gigaflops. That version of Deep Blue was only ranked the 259th most powerful computer that year.

The most powerful computer of that year was Intel's ASCI Red, which had a calculation speed of 1.06 teraflops, that's almost a hundred times more powerful than Deep Blue.

In November 2006 the most powerful computer was IBM's BlueGene, which has a calculation speed of 280.60 teraflops. That's over 24 thousand times more powerful than Deep Blue was.

So I exaggerated 'a bit' about there being a computer billions of times more powerful than DB, but as you can see Deep Blue wasn't anything special.

You forgot to take into account the the hundreds of special purpose chess chips which add to the speed significantly.

You claimed that Hydra can't match Deep Blue's speed. Hydra evaluated 200 million positions a second, just like Deep Blue!

The thing that most amazes me is that supposedly Kasparov claims he has never been able to look at the deep blue logs. Even though they were (and still are) available on the web. I could email 'em to him if he would shut that claim up.

Those logs have a problem. The logs on the ibm web site have no independent certification as being created by deep blue during the match. For the logs to be valid the judges would need to see them being created by deep blue during the game. The logs need to given to the judges during the match. The judges did not verify the logs on the ibm web site.

Sorry, but that's wrong. The logs _were_ verified _during_ the match. I even saw a copy of the key position's log emailed to me by Ken Thompson within 24 hours of the "fiasco" happening.

You seem to demand that they disprove a negative, which is impossible. There are way too many ways to actually pull off cheating without detection. But for every move DB found in that match that was questioned by Kasparov, other programs have since shown that the moves were not surprising at all and are reproducible by several different programs.

But the logs are available, they match the games, there's no unusual aspect to them whatsoever...

Bob, you were not an arbiter and Ken Thompson was not an arbiter. So neither of you could verify that logs were correct. Only the arbiter, Carol Jarecki, could verify the logs. This was not done. The logs should have been created in front of the arbiter and given to the arbiter after each game for same keeping.

The question is not if other chess programs could find the move. The question is did deep blue find the moves and could it do find them again. The question could easily be answered by having deep blue replay the games. Simple, setup deep blue and see if could replay the same moves. Oh, I forgot we couldn’t do that. Ibm dismantled deep blue so it could never play again. So it looks like we will never know if deep blue really played the moves.

Of course we know Deep Blue played the moves. IBM are not cheats
No doubt whatsoever in my mind.
