Opening performance of engines

[Dann Corbit]

This is the set for which your list of best moves does not match the move in my computer analysis. 19 of the analysis records are less than 36 plies, so not much value in an opening move analysis. I plan to analyze each one until it has a depth of at least 37 and an analysis time of at least one hour.

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

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.

I would like to suggest to make this opening test sets adapt the point system of STS, as in the opening stage there can be more than one best move, and for slightly inferior moves it is still useful and also all the analysis that is put into it will not be totally wasted.

Regarding ECO, I am now using scid.eco convert it to PGN and it has 10360 games in it, whereas the eco.pgn that I used previously had only 2015 games.

Sample result so far.

From Dann's post I think he can generate ECO, Opening and Variation easily and perhaps we can asks him to do this.

[Laskos]

This is the set for which your list of best moves does not match the move in my computer analysis. 19 of the analysis records are less than 36 plies, so not much value in an opening move analysis. I plan to analyze each one until it has a depth of at least 37 and an analysis time of at least one hour.

Thanks! This is done with Stockfish dev, right? On how many cores? What are the rules to accept a solution? I don't posses such software to analyze, generate ECO, annotations. I use Shredder Classic 4 GUI and work by hand. I tested 69 unsolved positions with Komodo 10.2 D=127, 25 were not solved in 2 minutes per postions, I am posting them here with "id" from Ferdinand's suite:

You are more experienced than me in this, what do you think, it's best to have all positions solved at very long TC by top engine, or leave some which are best according to databases, but not engine?

[Laskos]

I would like to suggest to make this opening test sets adapt the point system of STS, as in the opening stage there can be more than one best move, and for slightly inferior moves it is still useful and also all the analysis that is put into it will not be totally wasted.

I have doubts about even a clear-cut best solution, never mind point system for multiple optimal moves. Some positions come in stark discrepancy between databases and engine proposals. And there are different criteria with databases, popularity, performance, book selections. Maybe people can help.

Regarding ECO, I am now using scid.eco convert it to PGN and it has 10360 games in it, whereas the eco.pgn that I used previously had only 2015 games.

Sample result so far.

From Dann's post I think he can generate ECO, Opening and Variation easily and perhaps we can asks him to do this.

Great, thanks Ferdy, I am unable to generate such output. I have a question, what would be your philosophy, to have all solutions engine-solved at very long times, or to have a dose of database solely input? I favor more database-inclined approach, as some opening moves can be too hard for present day engines anyway. Also, an engine-oriented approach will bias the suite towards some engines (as it happens in STS with Rybkish engines). As of now, if I didn't do something terribly wrong, we have 25 positions unsolved by both Stockfish (very long times used by Dann) and Komodo 10.2 (2 minutes), your finding is there too. That's much less positions than I expected. I wouldn't be in hurry to throw them all away, and would judge more according to databases and books rather than deciding by engines solely. What is your opinion?

I will send the script and ref pgn later.

Something like a point system.


Database score can be based on W/L/D.
Opening book score can be based on play percent of the book.
Cerebellum score can be based on 1st choice and 2nd choice.
Engine ia score can based on score returned by the engine.

Hi Kai,

See if you find any openings from my FOSCEC test suites http://www.foscec.org/FOSCECTestSuites_1-0.zip useful. One has 90 lines of various length, another one has 1023 8-ply lines, meeting the needs of Arena. (Arena allows matches up to 2046 games long, hits a loop at 2048.) The larger one includes reductions of the lines from the smaller one down to 8 plies.

Curiously, I am not aware of any test suite testing the opening knowledge of engines in some quiet moves. I used databases of human and computer games and the excellent book Noomen.ctg to tentatively construct one, "Openings 200", starting with Jeroen Noomen "Short Lines" suite. The work is pretty sloppy, as it's hard to decide to me the equilibrium between databases, books and some engine output, and I am a weak chess player. Even solely with databases and books, there must be some trade-offs between popularity of moves, performance of moves, book marking of moves. It's more an art, but nevertheless, worth a try.

The link to testsuite in alpha stage is here:
http://s000.tinyupload.com/?file_id=662 ... 4776267887
The recommended time per position is in seconds, say 10 seconds. The results are not improving with the allotted time as fast as with tactical testuites. Some positions might not be solvable by current engines at all, but some positions are plainly wrong.

Several results at 10 seconds/position on 4 cores:

Code: Select all

Komodo 10.1          128/200
Stockfish dev        124/200
Andscacs 0.872       102/200
Houdini 4             99/200
Houdini 4 Tactical    95/200
Hannibal 1.7          93/200
Texel 1.06            91/200
Giraffe               73/200
Fruit 2.1             73/200
Sjaak 1.3.1           52/200

I wanted to check that I did not include some sharp search positions, so I included Houdini Tactical beside normal Houdini. Interesting that Andscacs performs better than Houdini. I had an impression that Giraffe is quite good in openings, but it came no better than Fruit. I am not satisfied with the suite, as for now even engines with very poor eval solve as much as half of the positions top engines solve. Also, I would guess 20-30 of positions have dubious solutions. Maybe people can contribute to building a better suite.

The positions are listed below:

[Dann Corbit]

This is the set for which your list of best moves does not match the move in my computer analysis. 19 of the analysis records are less than 36 plies, so not much value in an opening move analysis. I plan to analyze each one until it has a depth of at least 37 and an analysis time of at least one hour.

Thanks! This is done with Stockfish dev, right? On how many cores? What are the rules to accept a solution? I don't posses such software to analyze, generate ECO, annotations. I use Shredder Classic 4 GUI and work by hand. I tested 69 unsolved positions with Komodo 10.2 D=127, 25 were not solved in 2 minutes per postions, I am posting them here with "id" from Ferdinand's suite:

You are more experienced than me in this, what do you think, it's best to have all positions solved at very long TC by top engine, or leave some which are best according to databases, but not engine?

Analysis is mostly stockfish, but can contain Komodo or Houdini analysis. Unless there are at least 32 games, I consider the game outcomes as hints only. Unless there are hundreds of games, deep analysis is better. when there are thousands of games, then the game statistics are usually right. I also have a ce estimate based on games called cce. When the ccce score is better than the analysis score, I like to search deeper. When you get to either 37 plies or one hour (whichever is harder to achieve) then the move given is going to be pretty good, at least. There are some rare exceptions , especially with closed positions or gambits where the engines simply do no get it. We can sometimes discover the right move via stats. To get functional computer analysis in such a case, find some solution games and analyze them backwards. This almost always works. I always have several computers analyzing positions like this because they are the most interesting positions of all.

This is the set for which your list of best moves does not match the move in my computer analysis. 19 of the analysis records are less than 36 plies, so not much value in an opening move analysis. I plan to analyze each one until it has a depth of at least 37 and an analysis time of at least one hour.

I started a new thread that should help you out with the analysis, Dann.

[Ferdy]

Two-level analysis each with multipv 3. Root node or node 0 is analyzed at 20 minutes, nodes 1, 2, 3 (ply 1 - square shapes) are each analyzed at 10 minutes. Engine used is Sf8.



Cerebellum book prefers Bb4.
Engine analysis is plotted thru python igraph.

[Ferdy]

Root node at 20 minutes, other nodes 10 minutes.




Cerebellum prefers d6.
