The Alpha Effect

[Michael Sherwin]

A round robin fast time limit (10"1") training tournament, 1200 games from starting position.

RomiChess64P3n1
RomiChess64P3n2
Stockfish_8_x64_popcount

This is a hybrid self training and 'best' training experiment. Stockfish is nondeterministic in that it does not always play the same move. That means that Romi needs far more games to learn how to win against SF. But that is not the focus of this test. The focus is to train up to see if Romi will at least play the openings better. Then after this I will run two two round robin tournaments against multiple engines one with book_off and the other with book_on. Then performances will be compared. Currently from Elostat in Arena.

1 Stockfish_8_x64_popcnt : 2749 0 0 206 98.8 % 2149 2.4 %
2 RomiChess64P3n1 : 2228 46 46 206 26.0 % 2410 21.8 %
3 RomiChess64P3n2 : 2223 46 47 206 25.2 % 2412 22.3 %

So far 309 games have been played. Romi got her first draw in round 29. Romi also drew in rounds 101 and 103.

I will show 3 games. First how badly Romi lost in the Spanish Berlin in round 53. Then romi's draws in the Berlin in rounds 101 and 103. This will show a dramatic increase in strength in this opening.

[Rodolfo Leoni]

A round robin fast time limit (10"1") training tournament, 1200 games from starting position.

RomiChess64P3n1
RomiChess64P3n2
Stockfish_8_x64_popcount

This is a hybrid self training and 'best' training experiment. Stockfish is nondeterministic in that it does not always play the same move. That means that Romi needs far more games to learn how to win against SF. But that is not the focus of this test. The focus is to train up to see if Romi will at least play the openings better. Then after this I will run two two round robin tournaments against multiple engines one with book_off and the other with book_on. Then performances will be compared. Currently from Elostat in Arena.

1 Stockfish_8_x64_popcnt : 2749 0 0 206 98.8 % 2149 2.4 %
2 RomiChess64P3n1 : 2228 46 46 206 26.0 % 2410 21.8 %
3 RomiChess64P3n2 : 2223 46 47 206 25.2 % 2412 22.3 %

So far 309 games have been played. Romi got her first draw in round 29. Romi also drew in rounds 101 and 103.

I will show 3 games. First how badly Romi lost in the Spanish Berlin in round 53. Then romi's draws in the Berlin in rounds 101 and 103. This will show a dramatic increase in strength in this opening.

Greatly interesting. It remembers me the "Romi effect", with the difference that the whole world of computer chess was against your revolutionary ideas...

But after each test a lot of people was surprised by Romi's amazing performance.

[Michael Sherwin]

Yes, it was like sailing directly into the wind. Bob was truly against it. Richard Pijl the author of The Baron was the only engine author TIKO that embraced the idea and included it in the Baron. Others may have but I don't remember.

Romi fans posted on the Rybka forum about Romi's learning and practically begged Vas to put it in Rybka. Romi's fans asked other authors to put Romi's learning in their engines. If they have added learning somewhat based on Romi's I have not seen any credits. I'm hoping that the alpha effect will peak engine author's interest because if it doesn't then AlphaZ will leave them in the dust!

This helps explain why such a revolutionary new paradigm hasn't occurred sooner. A possible underlying cause could be a wrong perception of learning, as being at worst closer to a form of cheating, or at best just a cheap shortcut to chess improvement for engines, without all the years of tweaking and gradual gaining Elo. All this added up to a staunch and stubborn resistance to learning, refusing to let the future come to us faster.

Another problem is that the testing community has not embraced learning, because they're wary of distortions in their rating lists. There can be workarounds for that, though. Two versions of the same engine, and maybe even of the same rating list could be possible, one with learning, one without.

I hope a Romi-style revolution can still take place, spurred on by Alpha's shocking result. All the top engines could benefit a lot from reinforcement learning.

Michael, in this season, I wish you strength and good health and many productive years ahead.

Cheers,
CL

Thank you Carl. I appreciate your kind words!

Very interesting! This actually makes a ton of sense for the opening. What would also be great would be to implement something that allows massive amounts of Monte Carlo lines to be tried in real time via a GPU card that better prunes which lines an engine should search deep. This would be a force multiplier and is useful not only in the opening, but also in the middle game and end game. I spent quite a bit of time analyzing the alpha zero games and some of those moves are really out of this world. We always hear about "compensation for material" where something is sacrificed to get free movement for pieces or more space for bishops, or to restrict temporarily the movement of your opponents pieces or make him passive ... but with A0 you really got to see it in action and working against an extremely powerful SF setup. This shows just how rich chess is and that we probably still don't understand some of the nuances.

I wonder if using a GPU or even an FPGA card or maybe in the future an ASIC setup in combination with a CPU is possible. I don't know how A0 works, but if it is really pruning its moves and only searching 80,000 nodes per second ... the prunes must be very high quality.

Exactly!
