Experience Tests

Post by **Hurnavich** » 16/01/2023, 9:18

I'm trying a new experiment a different way to build EXPs i tried i think a first when i did a exp tour based on pgn trained exp to each individual engine games ie HypnoS exp trained from games played by HypnoS engine Ai exp trained from pgn of AI engine games so on see here.

....https://outskirts.altervista.org/forum/viewtopic.php?p=50941&view=single_post#p50941

Now here are another experiment way to use a ctg test book ie suite style see book created here by Peter following link

https://outskirts.altervista.org/forum/viewtopic.php?p=52029&view=single_post#p52029

what i have started now is running the book as per Peters recommendation against the engines from my previous tour some of the engines have been updated also pay close attention as Peter recommends that the same book is used during the engine tests not Separate instances this way each engine playes the reverse of the opening colour in Fritz GUi's.

Ok after running quality 4 min +1 sec game across x2 Ryzen PC's 3950x and 3900x and getting a good broad opening eco play db i then took the DB and trained a new exp from that db of GM v3 games ply was limited in play to 20 then increased in further games to 40 this gives room for games played with the new created GM-v3 EXP only, to let the engines add to the exp as it starts to learn from current game play.

Now add to this one pc plays with the exp and ctg GM-v3 against a stand alone engine with exp only different to the GM-v3 and builds new games to add to the holding DB which will be used to tain a bigger EXP based on the dual ctg exp GM-v3 combo. The other pc plays GM-v3 exp only to build games from that source against other strong books exp's as both set up's grow the ply is increased here are some eg games.

With CTG GM-v3 ply limited eg

Eventually we will have an EXP based on the play test suite book of Peters that will be able to take on any book ctg bin exp or dual and hold its own with wide eco play.

Eventually we will have an EXP based on the play test suite book of Peters that will be able to take on any book ctg bin exp or dual and hold its own with wide eco play.

An interesting experiment Ian.

This leads to some other possibilities where for example a further comparison could be to integrate the learned database into the book that for blitz games could give an additional time bonus.

It may need more than 24 hours a day to complete though and I do not envy the energy bills!

Here is an eg of using the book correctly as Peter suggests using the same instants for the book not separate instances to test engines as we can see here the engines played each side of each opening played AI-29.5 won the return game in this case.

I share with you a curious variant of the Sicilian B33 defense that, even having trained said position, Eman values (shallow analysis, blitz games) with equality, Stockfish the same until Black's blow arrives, sacrificing the bishop on g3. Although it is clear that if we let black get the f-pawn to square 3, tragedy is coming. But engines like stockfish that don't use experience don't see it either. I leave the game to see what you think

(Jorge, Terrassa 24.07.2023)

Here still stopckfih still sees 4 points in favor of white. On the contrary, Eman, who has already played this position six times in just ten seconds, mates in 13. It is possible that the opponent has some wrong parameter, but Omar caught me with this variation five times, until I reviewed the game and put it to work.
It must be said that you can get to the same position by transposition and in my opinion I think that you have to avoid that f3 at all costs.

Regards!

MY first analysis of a pgn base with Eman games ending in checkmate. The analysis and creation of the experience file has been done with Eman Tools, very similar to Stockfishmz tools, but I don't know why with Eman you can spend days for this. With only 207 games I think it was two days with two instances, 8 cores per instance, 4096 hash and emanation 9.31. I hope it can be useful to you.

Second test to create a learning file from a pgn database. In this case, the size clearly indicates that it has been made with a single-movement file. I share a screenshot of how it was done.
