At the end I have the same t-value but the rest is for some reason different. I think the reason may be that I'm counting 500 games and you probably 1000 (I'm guessing)? My normalized elo is 0.4446 and multiplied by sqrt(500) gives 9.94.
Normalized Elo is t/sqrt(2*500), no?
You're probably right, it seems I missed factor 2 somewhere. I will look at it tomorrow.

I created two experimental books (both are small subsets of 2moves_v1 book). I would like to know if you can get any significant difference in sensitivity of those books. I don't say on purpose what they are and I have cut them down to the same size to not suggest anything (to have kind of blind experiment). Maybe it's nothing there. I tested them with SF 210617 but with quite small number of games. I would be interested to see results from others with maybe other engine/CPU speed/time control, etc.

I will test them tomorrow in probably 2000 games each, at most 4000, at 6'' vs 3''.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.

Re: Opening testing suites efficiency

Post by Michel »

I am a bit worried that by using unbalanced endgame positions for tuning, the engine will not learn to play balanced positions (with current data, it is impossible to know of course if this would be a real issue).

It seems an alternative to using unbalanced positions may be to simply give the white player time odds.
Ideas=science. Simplification=engineering.
Without ideas there is nothing to simplify.

I don't say on purpose what they are and I have cut them down to the same size to not suggest anything (to have kind of blind experiment). Maybe it's nothing there. I tested them with SF 210617 but with quite small number of games. I would be interested to see results from others with maybe other engine/CPU speed/time control, etc.

Books 2moves_A and 2moves_B (link expires in 7 days): http://dropmefiles.com/7Ga0j
I will test them tomorrow in probably 2000 games each, at most 4000, at 6'' vs 3''.
Tested with Komodo in 2000 games each. Not enough games to clearly separate them, but an indication that A is better. Both come very well compared to other suites (2moves_v1.epd included), I don't know what did you do. I tried without success to optimize significantly 2moves_v1, but all came at most to the level of your B. A was pretty much ahead (but again, 2000 games are too few).

Results:

2moves_A.epd
Score of K2 vs K1: 1171 - 120 - 709 [0.763] 2000
ELO difference: 202.87 +/- 12.78
Normalized ELO: 0.865 +/- 0.044

2moves_B.epd
Score of K2 vs K1: 1166 - 134 - 700 [0.758] 2000
ELO difference: 198.34 +/- 12.85
Normalized ELO: 0.833 +/- 0.044

Here is the distribution of Stockfish eval on 2moves_v1.epd positions. This might help you optimize it, it has a great potential for optimization.

Mean: 18.16cp
Median: 20cp
Standard Deviation: 41.2cp

Errors (95%) for Normalized ELO here are all = 0.062


Balanced 2x time control (10s vs 5s):
Endgames unbalance 0cp-40cp:
Score of SF2 vs SF1: 28 - 8 - 964 [0.510] 1000
ELO difference: 6.95 +/- 4.06
Normalized ELO (trinomial): 0.106


Balanced 8x time time control (20s vs 2.5s):
Endgame unbalance 0cp-40cp:
Score of SF2 vs SF1: 58 - 4 - 938 [0.527] 1000
ELO difference: 18.78 +/- 5.24
Normalized ELO (trinomial): 0.222


Unbalanced 2x time control (10s vs 5s):
Endgame unbalance 100cp-140cp:
Score of SF2 vs SF1: 299 - 187 - 514 [0.556] 1000
ELO difference: 39.08 +/- 14.99
Normalized ELO (pentanomial): 0.315


We can treat SF1 and SF2 as different engines (although they are the same engine with doubling TC), and what we did is quadrupling time for one engine compared to another. The result is not enchanting. Draw rate decreased only from 96.4% to 93.8%. The sensitivity increased, but not to the level of unbalanced set to positions.

I am not sure Normalized ELO is invariant in doubling TC for every TC. That would be an interesting question, as ELO differences decrease and WILO differences moderately increase, and Normalized ELO is somewhere in between. My guess is that quadrupling at ultra-fast time controls gives more difference in Normalized ELO than quadrupling at longer TC. So, to have even this mediocre result replicated at longer TC, one would need more than quadrupling. One would end, for having significantly higher sensitivity, to play bullet time controls against tournament time controls. I am not sure that's feasible, and in Checkers they didn't go this way (IIRC).

EDIT: Maybe I should explain what is the interpretation of this test. Stockfish at 2.5s is the weak engine. Stockfish at 5s is the strong engine. First 1000 games match is the weaker engine at 4x TC advantage. The weaker engine won by Normalized ELO of 0.106. Second match is stronger engine at 4x TC advantage, 1000 games. It won by Normalized ELO of 0.222. The difference between these two numbers matters and their combined error. The result is mediocre, as you can see. The last match is simply the two engines head to head without time odds from unbalanced positions using the pentanomial variance, absolute value and simple error is all that matters.

Great! Thank you for this work, very important for engine testing.

Do you think others can distribute this file?
Good stuff Kai and the thanks for sharing. I understand that they choose to to use 2moves_v1.epd was to reduce draws and get test results, yea or nay back faster. My complaint about using the book is that missing an opportunity to fine tune the strengths of Stockfish to more commonly used openings.

They do have use a book for regression testing that has the more commonly used lines which I like.

http://www.talkchess.com/forum/viewtopi ... ht=#720389

I'm not expert enough to say which way is better - but my suspicion is using lines that are totally skewed from normal chess openings probably increases the chances of getting patch approved that does not add elo or even worse, loses elo, since you starting with game play as what I would call a defective position, defective is that they are using positions the engines would never see in a real game.

An extreme example would be to use opening lines that perhaps looked like this?

[d]8/8/8/2p5/1pp5/brpp4/1pprp2P/qnkbK3 w - - 0 1 - obviously one would not - but it's sort of like the old man asking the young woman to go to bed with him for $5,000,000 - and she saids "yes". Then he offers her $100 and she says "no, what do you think I am - a prostitute?" and the old man replies replies , "we already established that , now we're just negotiating price". I believe SF would be even better if they simply use normal type openings for testing, but there is no way I can prove that and you cannot knock their success - but using random 2 move openings does little for tuning an engine for opening play.
