Strelka 5 by Yuriy Osipov

[A Distel]

You really sound like a broken record...

Ik beloof dat ik zal het kort en zoet ('short and sweet') voor u maken.

Ik wist niet dat je zo goed "Vlaams" kon schrijven!

Dag Alain-
Ik spreek vlot Nederlands (maar schrijf met spelling foutjes), en mijn Frans is redelijk goed,
want ik ben getrouwd met een Vlaming, en nu twintig jaar wonen hier in Brugge...3 kinderen al hier gekocht.
Helaas, ik ben nu een deel officieel Vlaams!

Vriendelijke groeten,
Norm

I don't mind Jury's efforts (imitation is the sincerest form of flattery), I'm just fascinated by people's reactions, even from educated people like Kai.

Hi, Robert !

I would like to send you the source code of Strelka 5. If you don't mind.

Jury, have you heard anything about this new [in the last week] private version of Robbolito that will be released in a couple weeks. Supposedly it destroys Houdini 2. Couldn't get much info on it.

Hi Robert
Read the article about you in this months issue of Selective Search

nice photos
beautiful child you have there ..your a lucky man..everything else pales in comparison to that which i guess you realize already
if you want to avoid all of these negative posts just take my previous advice
establish your own forum while Houdini is all the rave and let the members defend it for you

Someone will fill the void left by Vas. Someone with a top engine will do this. In the fast moving computer business it won't be long before someone takes that step. Question is will it be clones or ?

Ippo and Stockfish based for sure.

I have to admit, i haven't followed all this new Stelka5 stuff, therefore my question - Is there a Strelka 5 MP version?

I'm smelling a parody of obfuscated C code, adorned with easy recognizable chess programmers idiosyncrasies.

But I may be completely wrong, maybe some funny pic?
Why not the last Playboy playmate but with a (somewhat feminized) Vas head?

Not so funny to be out of a private joke prolonged on a public forum

Would you mind sharing the info you did manage to get ?

Strong result from Strelka 5 with the new x64 compile

Code: Select all

    Program                            Score     %        Elo    +   -    Draws

  1 Houdini 1.5a x64               : 1114.0/2180  51.1   3204   12  12   34.0 %
  2 Strelka 5                      : 1066.0/2180  48.9   3196   12  12   34.0 %

Only 8 +/- 12 (95% confidence) Elo points weaker than Houdini 1.5a.

What is the time control?
I guess it is something like 6 seconds per game+0.1 second per move otherwise you could not have time to get so many games.

If you can make another match between them at time control that is 10 times longer then it may be interesting.

I used 4x time control, 4s + 0.4s, ~1 minute/game.

Code: Select all

    Program                            Score     %       Elo    +   -    Draws

  1 Houdini 1.5a x64               : 2122.0/4120  51.5   3205    8   8   36.5 %
  2 Strelka 5                      : 1998.0/4120  48.5   3195    8   8   36.5 %

Strelka 5x64 is weaker than Houdini 1.5ax64 by 10 +/ - 8 (95% confidence) Elo points. A new x64 compile of Strelka will probably be available soon.

I am not sure I quite buy that 10 +/- 8. It seems closer to 10 +/- 16, because each individual rating has a +/-8 error. When you subtract, both error bars should be included.

No Bob, that's simple. In an individual match the error is exactly 8 Elo points 2 standard deviations (95 % confidence). If one compares two individual results in a rating list comprising many independent, individual matches, giving X Elo points for both engines total error in the rating list, the error comparing these two engines is X*sqrt(2). In a rating list of many independent matches, one engine having an error X and another Y, the error when comparing them is sqrt(X^2 + Y^2).

Kai

I'll take your word for it. The way the data is displayed, such as 3208+/- 8 suggests that could be 3200-3216 with 95% confidence. Ditto for the other. That seems to match with the way BayesElo displays things, as that is the program I use in my cluster testing...
