- - By dragon49 (****) Date 2008-08-07 22:56
I was so eager to play her yesterday, that I have not yet launched the Aquarium Interface.  I used the Fritz 11 Interface to create a UCI engine and started playing G 15 Games Between Rybka 3 1-cpu 32 bit and Fritz 11.  At first I was shocked after a 4 game match.  Rybka using compmaster Beta 2.0 ctg and Fritz using Fritz 11.ctg, both using tournament book 4 games minimum up to move 22.  Fritz 11 won the match 2 1/2 to 1 1/2, without Rybka winning any games. 

Then, I downloaded and had Rybka use rybka2.ctg.  I changed both book options to use up to move 25 and played 52 games at G /15.  Rybka crushed Fritz with a score of + 25 -3 = 24!  I am very impressed.  I am going to play another 52 games giving Rybka the compmaster book in an effort that will hopefully prove that Rybka is just as strong without a book made for her.

It is funny watching her low kN/s.  The unit of measurement that Rybka uses for nodes per second is clearly different then the one that other engines use.

It is time for me to stimulate the economy by getting a 4 or 8 core pc to watch Rybka at her best.

In the meantime, I have a question: 

With a single core cpu, will the multi cpu version play exactly the same as the 1-cpu version?

Thanks

I can't wait for the 8 core Nahalem platform from Intel to arrive. As soon as it
is available, and assumimg I have Rybka 3 and Jerome's book to go with it,
I will buy this PC. It should produce stunning results. I can only hope that
Vas and Larry look to Intel for sponsorship for a match with the human world
champion (Anand, Krammick, Topalov) for a match. The conditions should be
a non-handicapped match, and a PC that we all can buy from Dell, HP or Best Buy!
In other words, an 8 core Nahelem platform. Let the overclockers go from there :)

Heck, maybe they should try to bring Microsoft in on this challenge as well.
Microsoft might be interested in sharing the cost with Intel. 8 core Nahalem and
64 bit Windows Vista Ultimate platform against the human world champion.
I don't know if I should dare say it, but maybe the match should be at some
kind of pawn and move odds. Let these two giants pay the cost if a top 10
human GM can win this match. They are collecting our money as we speak to
sell this system for the sake of computer chess. :)

Of course we would be glad to play such a match, but for us and most informed people there would be little point, everyone should understand by now that the human has no chance. I would be much keener to see a handicap match, but I guess a World Champion would be too proud to accept a handicap.
Parent - - By garyf919 (**) Date 2008-08-08 06:35
Larry, I know exactly what you mean, but let the world champion agree to your
conditions or make his own! And let Intel and Microsoft agree to what those
conditions are also, as they fork out the money to host this event. Even just
this thread of comments, and a good marketing person on your staff could get this
challenge done. It's a win for all except the poor top 10 GM that accepts the
challenge. And if his ego is really large, have the sponsors offer a large sum of
money at a standard (non-handicap) match, and then if the GM loses, a rematch
at pawn and move odds. This would be the most exciting event in chess history,
next to the Fisher-Spassky match.

Mispelled Bobby's last name. Sorry all, about that.

And then you mispelled misspelled/misspelt. :) You can still edit your original post - the edit window is 60 minutes.

LOL, thanks :)

Does this website have a spell check feature? :)
(I almost failed my English composition course as a freshman in college).

"a good marketing person on your staff". What staff?
Parent - - By InspectorGadget (*****) Date 2008-08-08 07:15
Hi Larry, maybe the handicap should be that Rybka's book is limited to 3 or 5 moves, but no material odds.
Parent - - By lkaufman (*****) Date 2008-08-08 13:17
Yes, that plus all White pieces (as with Ehlvest) might be enough to at least make such a match LOOK reasonable.
Parent - By InspectorGadget (*****) Date 2008-08-08 13:25
plus all White pieces

I wanted to mention that, but... I didn't want people to attack me, hahahaha :)

the human has no chance

How unarguably true, and what a sharp turnabout from the brash remarks I saw Kasparov make in April 2000 at a Stanford lecture, when he said computers would not truly surpass top human players until maybe 2015.  I guess he knew when to retire.
Parent - - By lkaufman (*****) Date 2008-08-08 02:44
It should play the same moves if you reproduce all the conditions exactly. In a timed game this is impossible, but if you search fixed depth, you should get the same moves. But details can trick you; for example setting up a position or playing moves to get to it will often lead to different moves being chosen, even on fixed depth.

The time where a human can challenge a strong engine like Rybka on strong hardware has long past.  I think even a SP Rybka 3 would crush the strongest player on earth ... but it would be interesting to see how many draws and maybe a rare win here and there.  Let us forget the idea that a human can win a match ... but I think that with enough games played a human will be able to get draws and even the occasionnal win.  Maybe a good challenge match should be that a human wins if he can manage one win in 10 games with the engine playing at full strength.  I really think a top GM would consider it demeaning for him to have a won position from the start and ask him to not lose it.  If he wins ... all it says is that he avoided any errors ... if he loses ... he looks like crap.
Parent - By lkaufman (*****) Date 2008-08-08 13:21
Requiring one win in X games is not suitable because it just forces the Rybka team to choose drawish, boring openings. As for a top GM considering it demeaning to start with a won game, if "top 30" is top then at least one does not agree. But you are probably right regarding those in contention for the #1 spot.
Parent - By TedSummers (***) Date 2008-08-08 13:22
I don't know about that, after all GM Roman Dzindzichashvili did not do so bad when he played Rybka 3 on 8 Cores. I think he would have won if Rybka 3 was on a SP system. I think you give Rybka 3 to much credit here.

Why this confinement with strong hardware? I´m absolutely sure you can go with every normal notebook with C2D processor to any chess tournament and you will win with distance with R3 and normal good opening book. In a double round tournament against Top 6 (Anand, Carlsen, Ivanchuk, Moro, Topalov and Kramnik) she will make at least +5 with this equipement.

Yes.

Thanks,

Then why the need to distribute the 1 -cpu version?
Parent - - By George Tsavdaris (****) Date 2008-08-08 23:36
:-)
Just look at the prices.....
Parent - - By dragon49 (****) Date 2008-08-08 23:44
I should have been clearer.

I purchased the complete Deep Rybka Aquarium Package which included a number of different 32 and 64 bit UCI Engines.  I was questioning why the need to distribute th single cpu UCI when the Multi cpu UCI works with single thread cpu's.
Parent - By George Tsavdaris (****) Date 2008-08-09 07:53
Oh so you're saying the Deep Version packages contain, except of course the 8 Deep Rybka 3 EXEs, also the 8 Single Rybka 3 EXEs.....

Yes that is a question. Perhaps in the sense of completeness, what can i say?
Parent - By Vempele (Silver) Date 2008-08-09 08:06
Because otherwise we'd get a flood of people asking (again) whether the MP version can be used in a SP computer.
