Evaluation score looks good on a couple of positions I have tested - anyone have any views on this engines chess playing ability?
Parent - - By WeatherTheStorm (*) Date 2012-04-24 05:44
Is there any plan to make Strelka support multiple processors?

Thanks

The x64 version will be released in the middle of may.

>Evaluation score looks good on a couple of positions I have tested - anyone have any views on this engines chess playing ability?


Brilliant engine - top tactical!!  In the "AH_Tactics test suite", it solved with 10s limit 248 out of 250 positions when the previous nr one, 64b MP Critter solved 246 positions.
You can download the "AH Tactics-250" test suite for Arena 3.0 GUI here:

Thank's Yuri Osipov for this free engine!

I read that it simply remember the solution for test positions and if you change the place of some unimportant pawn it is not going to do so well.

100 games with 1 core per engine with pondering says Strelka's strength lies between +38 and -130 Elo with 99.7% prob. compared to Houdini 1.5a
TC = 10 sec/game +1 sec/move incremental

Click on the PNG pic above to download PGN games from another site :eek: (fun for fans only)

For example in this 100th game even gaviotas didn't save Houdini from playing 67...h4? by zeitnot. Baah! Stinky clones!

In such a short time? Strelka wins by 51 Elo in this match of 1344 games,
10 sec/game. Adjudications by time were removed.
1   Strelka 5.5         +519/=501/-324 57.25%  769.5/1344

how is it so strong?
Parent - - By Barnard (Bronze) Date 2012-04-29 22:33
10 sec/game

if games are played soo fast,and Strelka (only pure speculation) is very good playing bullet games,you can see that type of rare results,since strelka is a clone of Houdini 1.5 (maybe version 5.5 a clone of Houdini 2)

but if you play 'normal' games at normal time controls,you will see that Houdini will win against Strelka
Parent - - By Geomusic (*****) Date 2012-04-30 02:00
I see so they took out knowledge so its faster?
Parent - By Barnard (Bronze) Date 2012-04-30 02:29
it seems to be...or Osipov simply tuned the engine against Houdini,is another chance
Parent - - By Pia (****) Date 2012-04-30 08:47

>10 sec/game


10 secs with pondering equals at least 5 minutes on Pentium/200 MHz.

P.S. 10 secs is not enuf, 100 games is not enuf, 1000 games is too fast, 100 games is too slow, idk what ya need :cry:
Parent - - By Barnard (Bronze) Date 2012-04-30 16:53
Hi pia

I never criticised your work,i just told that maybe Strelka plays vera well bullet chess,or is tuned to play against Houdini

Apart from that,if you do that test,are good from the point of the statistical scorin points...

But if you try to mame the test with more time,les say 2 minutes for the game,maybe the store will change

In all cases,thanks for sharing your results
Parent - - By Pia (****) Date 2012-05-01 03:48
Well, I did. 4'+2", 24 games played, score +7 =10 -7
Houdini 1.5a using 1 core, pondering, no gaviotas, Perfect 2012.

thanks in advance
Parent - - By Pia (****) Date 2012-05-02 10:08
But it's only 25 games (PGN). Out of 200 I almost sure, Strelka would win.
Parent - - By Barnard (Bronze) Date 2012-05-02 15:17
why you dont run the 200 game tournament,and we will se who wins? :smile:

but using Houdini 2.0c and strelka 5.5,that im sure is the RE of Houdini 2.0c (or maybe the b version,since the c is only a bug correction)
Parent - - By Pia (****) Date 2012-05-03 11:29
Update. See the pic bellow?

Match will end after 200 games played. For now, Houdini looks like as an expensive piece of junk.
Probably setting contempt to 0 would help, later...
Mr. Houdart was so kind to implement strength-weakening technology if you enter incorrect registration code.
Hopefully, I'm avoided this trap. For testing purposes :razz:
What's more? I can't remember... For just you only to know... Vodka Belenkaya is the best sort! Of vodka... errr, I forgot my inglosh...

Pia,dont tell at public about pirated engines,you are at risk to be banned,even if it was only for test purposses...I DONT MAKE AND I WONT MAKE APOLOGY OF PIRATING ANY ENGINE,who wants use pirate engines,dont need my help and know where to look :wink:

from what i read at his facebook page,if you enter an incorrect serial/use a pirated engine with a wrong serial,Houdini plays 150 elo points weaker than the 'original' Houdini,not enough to be detected if you dont run tests,but enough to start you lossing games if you play at playchess,for example

so i think he implemented a good measure and a good elo number,not too high,not too slow

p.s.i recall that information is given AT HOUDINI's FACEBOOK PAGE,AT PUBLIC SITE,WHERE EVERYONE CAN READ IT AND WITH THE PURPOSE THAT EVERYONE READS IT...NOT PIRATE SITE...SO NO REASON TO DELETE/MOVE THE POST

p.s.what about Stolichnaya vodka?i have a bottle...directly stolen from my father's home :lol:

*whispering* yes, let us afraid of K.G.B. Nevermind that Houdini's a clone of Ippolitto/Robbolitto Rybka derivatives itself.

Parent - - By Barnard (Bronze) Date 2012-05-03 22:29
well,since strelka is a clone of Houdini,should play very similar in strength to Houdini,so the match will end very similar to score

Parent - By Uri Blass (*****) Date 2012-05-01 08:29
No
It is not equal because I suspect that the time management is different.

some engines for example may have a rule to search only to depth 1 when the remaining time is less than 1 second regardless of hardware(something that does not happen often in 5 minutes per game but happens often in 10 seconds per game).

Some engines also may have a rule to check if the opponent made a move only every 1/10 second that is not very important in 5 minutes per game but can cause a problem in 10 seconds per game.
Parent - - By Uri Blass (*****) Date 2012-05-01 08:38
My guess is simply that strelka has better time management for 10 seconds per game relative to houdini.

Note that copying from houdini is no explanation for the fact that strelka is better at this time control and you need to do some change to make the thing better
at 10 seconds per move.
Parent - By Pia (****) Date 2012-05-01 11:57
Here's some result at 10 depth/move. Strelka winning and she ~ x1.16 faster to that depth.



PS, games playing fast, it's now 270 games and 45 Elo Houdini losing;
need to change to deeper depths...
Parent - By Pia (****) Date 2012-05-02 11:43
Also, Strelka wins at 14 depth/move time control, like 10 and 12. Using less time, too!

ugh my Q6600 desktop just bit it before it died it was reading temperatures of 156 F degrees on each of my 4 cores. Not goood! I clean out the entire system (psu and all) every year or so can't have collected that much dust between the heat sink and the fan. Maybe a voltage connector shorted out. But that wouldn't explain the high temperatures! I could almost cook a steak on the cpu!
