Some Notes:
Used unsolved positions in 3 seconds/move, 1 core on i7 980X 3.33GHz
Exception Stockfish and Houdini, Crafty surpassed the formula rules too !)
As we see, the above mentioned engines did not follow the old formula ^0.76
It looks like, Rybka is more near to this old formula, but again in case of comparing the speeds:
- We can not use the strict number ^0.76
or it does not mean if same kN/s values, the playing strength should be same !
But however, the kN/s values are more useful for majority of the chess programs !
Continuing...
For example, I can say the same thing in case of doubling the processor speeds,
It will be wrong, if we use any strict formula ...I mean some engines gain 50 Elo, some 60 Elo etc...
Also it is similar issue, in case of increasing the time controls on same hardware...
For example, as far as I remember in one of my testings:
Rybka 30m+1s started to be stronger over Stockfish 1m+1s
In other words,
As I mentioned before, it all depends on our used conditions
For example here are some main factors, which are playing a very BIG role:
Hardware speeds, engine versions, opening books, time controls, etc..
Details,
- Stockfish 251015 (Author: lucasart) performed 13 points less than StockfishTS 240915
- NirvanaChess 2.2 x64 performed 18 points better than NirvanaChess 2.1c x64
- Protector 1.9.0 is bugy as previous its versions (performed much worse: 157 points)
* Protector 1.8.0 is tested via Polyglot adapter, where v1.9.0 as native (UCI)
- The latest Donna 3.1 x64 version does not support analyze mode too
- Pedone 1.3 x64 performed 3 points less than Pedone 1.2 x64
- ProDeo 2.0 w32 performed 5 points less than ProDeo 1.87 w32
- Maverick 1.5 x64 performed 5 points better than Maverick 1.0 x64
- NanoSzachy 4.1 x64 performed 1 points less than NanoSzachy 4 x64
- CyberPagno 2.3 w32 performed 8 points better than CyberPagno 2.2 w32
*CyberPagno, Maverick, NirvanaChess are the only ones in this update,
which managed to scored better than older versions...congrats to their developers !
More Details,
Probably I will publish my used EPD database after when X chess engine will pass Houdini !)
So till to this date, TTs test positions are planning to be kept as private (as before)
And I really wonder: who will be this hero ?) who will be able to add best tactical improvement!
I've decided to create a new blitz rating list by some of the top engines...
As we see, Stockfish is the current leader - my congratulations to Sockfish team !!
Note that the rating database includes 3000 games, where 9 games are lost on time
For example here are the chess engines, which have lost on time:
Komodo: 4 games
Stockfish: 2 games
Fire: 2 game
Houdini: 1 game
Rybka and Gull have no any game lost on time !
It looks like some engines are weaker, but more stable under current conditions !)
Note also that I've played a new duel match: Stockfish vs Komodo
2 games at very slow time control: 600 Min + 30 Sec
Engines are used 6 cores, Ponder OFF, No tablebases
Yes...the both Titans could not beat each other and the games are ended as Draw:
Я вот думал, куда пропал уважаемый Седат, мой большой товарищ! Он размещает фото в интернете. Надо будет ему позвонить, как вспомню номер турецкий. У меня накрылся телефон недавно, полетели медным тазом все номера, в том числе и номер телефона Седата. Может в личных сообщениях на сайте найду, он ведь должен мне писать, правда у меня личных сообщений более тысячи, долго искать.
