Rybka 4 versus Shredder 12

[Sergei Markoff]

Why not Stockfish, Naum or Strelka 3?
Strelka 3 is stronger than Rybka 3,

How do you say that? Based on what testing results?

I've seen a stronger modifications made by Yuri, but I think it's not a good idea to reveal more details because I haven't a permission from both Yuri and Vasik to talk about it...

I hope Yuri will say more to community, but it will be his descision.

Here is a question for you, would the author of Shredder be able to look at the code of Rybka 4 and incorporate the best ideas in Shredder 12 to increase it's strength?

It's not so easy as you make it seem. In fact it's way more complex. And even if he reads the code and understands it, it may not worth nothing in order to improve Shredder. So he would just have lost his time without any gain.

Also Shredder has improved and has increased its strength in the last versions, so what exactly are you talking about?

You mean to reach Rybka's level? Perhaps that will happen in the next versions and perhaps Shredder 13 will even surpass Rybka 4 or even Rybka 5.

Fascinating how someone can type so much without saying anything meaningful

I think SmarThink 3.0 will be clearly stronger

Good luck with your upcoming release of SmarThink Sergei

Thank you

Hello chess friends,

Shredder 12 will be released soon if it already has not and Rybka 4 will inevitably released soon. Does anyone have an opinion on how close Shredder will be to Rybka 4 this time around ? May be within 100 ELO or 50 ELO.

Thank you in advance,

Shredder 12 is already released, and is ~90 Elo points behind Rybka 3 32Bit, for 64Bit it is ~120 Elo points behind. It is not even clear that Shredder 64Bit is above Naum 4 64Bit on multicore. As for Rybka 4 64Bit we can only guess, probably more than 150 points stronger than Shredder 12 64Bit. No contest. Look for news on CEGT and CCRL sites.

Hi Mr. Markoff,
I am looking forward to the release of SmarThink 3.
I would like to know if the new chess program is going to going to be capable to use multiprocessor computers.
Not been able to use multiple processors can really handicap the program in the era of new programs who are also set for for 64 bit use so I hope that the new SmarThink 3 would be able to do it both ways.

SmarThink 3 is just a joke. New SmarThink version will be 1.20
x64 version will be included, MP still no but we're planning to make it in next few months.

You were a naughty boy Mr. Markoff with that SmarThink 3 joke.
But on the serious side how can single core engine compete these days against MP 64 bit engines.
I have downloaded Strelka 3 but it is only SP engine.Will do some testing to see it's strength compared to some MP engines.
I think that SmarThink would be even stronger if able to use MP capabilities.
I mean, you have seen the comments about Ktulu 9..Why even make engines that can not be used on MP computers.
So, I will be waiting for SmarThink MP program.
Best wishes for successful program.

SP engines can be used on MP computers

If your problem is the strength of the engine than most MP engines are weaker than Rybka SP even if you give identical quad to both programs.

Hi Uri,
what I meant to say was that SP engines don't use the full potential what MP computers can offer.
The other problem is that Rybka is so strong that as you said even Rybka SP can beat many MP engine on MP computers.
But when MP computers offer advantage compared to single core use why not make programs that can benefit from it.
