Opening performance of engines

[cetormenter]

I ran my current Nirvana dev on this test suite using 1 core and got 84/200. For reference the latest Andscacs got 80/200 under the same conditions.

Extrapolating from your results 80/200 = 106/200 84/200 ~= 110/200. Still a large gap between it and the top two but it is encouraging.

Tried to add eco, opening name and variation name and suite id, like to see the distribution of the openings.

I use the eco.pgn as reference from here.

I find Kai's 4 core results very strange, because my 4 core test gave only:

10s: SFdev 99 Komodo10 97
60s: SFdev 123 Komodo10 118

You have really fast PC?

I am using Shredder GUI for EPD testing. I think in Shredder position is solved after 3 consecutive hits or at time. What do you use? My PC is 4 core i7 4790 at 3.6GHz.

This position isn't solved by Komodo either in 2 min/position test. Human databases show Na5 and b6 being far less popular than proposed ones as bm by factors larger than 10. I am not sure what to do with it. Thanks for testing it, will enter into dubious solutions.

Thanks for the work of putting ECO, suite numbering (I planned numbering too) and names of the variations. I see that most don't have ECO classification, as I dug deeper into variations for finding hard to engines positions (non-tactical). Some of the root positions from Noomen Suite were weird already from the start, with no ECO.

I tested with Komodo 10.2 and latest SF at longer time controls too, here are the 4 core results:

Code: Select all

                       10s      30s    120s

Komodo 10.2 D=127    131/200    144    154
Komodo 10.2          125/200    138    148   
Stockfish dev        124/200    137    145
Andscacs 0.88        106/200    124 
Houdini 4             99/200    114
Houdini 4 Tactical    95/200    110
Hannibal 1.7          93/200    104
Texel 1.06            91/200    109 
Fruit 2.1             73/200     80 
Sjaak 1.3.1           52/200     57 

I found that by adjusting a bit Dynamism from default 117 to 127 in Komodo 10.2, the score improves probably above a statistical fluke. However at 1 second per position, the score with the default is higher (in five averaged tests). Maybe testing in games at TC like 60''+0.6'' (as probably Komodo team does) is showing D=117 as optimal, but LTC games would favor D=127. The result of 154/200 by this adjusted Komodo is encouraging again, as maybe only 10-20 positions are wrong, and this suite approaches STS quality. I didn't expect my novice in this and weak player work to be of some quality.

Well spotted, typo! Thanks!

I ran in Fritz GUI with 5 plies to keep. But it has also undocumented minimum time feature something like minimum time = 1/10 of maximum! Isn't Shredder GUI accepting 3 ply solutions?

Yes, Shredder seems to use 3 plies to keep. I had experiences with Polyglot when using different number "to keep" (delta), different lower limit of plies, gives different result. Maybe that's the reason?
