Andscacs nnue 0.1

Post by cdani »

Hello!
I was curious about what could I obtain adding nnue to Andscacs.
I went straight to nnue probe of Daniel Shawul:
https://github.com/dshawul/nnue-probe
After some work, manual tuning and testing, the result was beyond my expectations:

Code: Select all

50+0.5 
   # PLAYER              : RATING  ERROR   POINTS  PLAYED    (%)
   1 Andscacs 0.95183    : 3042.4   14.5    620.0     695   89.2%
   2 Andscacs 0.95143    : 2669.6   14.5     75.0     695   10.8%
So more than 350 elo in self play!

Here the Windows executable and latest Stockfish nnue net:
https://1drv.ms/u/s!Aj8wlSmr_Hq3islynT1 ... Q?e=FVH5CN
You can change the nnue net, just overwrite the nn.bin file.

Of course rating lists that care about engine originality should not add this version.

Is a bit far from Stockfish, but is not bad:

Code: Select all

500+2
   # PLAYER              : RATING  ERROR   POINTS  PLAYED    (%)
   1 Stockfish 311220    : 2961.6   20.8     83.5     109   76.6%
   2 Andscacs 0.95183    : 2750.4   20.8     25.5     109   23.4%

:( I'll stick to plain old Andscacs. There are more than enough Stockfish nets floating around.

Thanks for the new Andscacs Dani. Good to see you start working on your engine again. :) :)

Hmm... 350 Elo doesn't seem to much - I had around 600 Elo gain in BBC which is very very basic but stil 2900+ at CCRL:
https://www.computerchess.org.uk/ccrl/4 ... NUE_64-bit

I think if you tune eval pruning and make 100% sure to give 50rule move penalty in eval() it would be much stronger.
Without 50rule penalty SF NNUE failed to find checkmate in KQPK endgame in my case.

Anyway congrats with your experiment - this is obviously fun!
I wish someone created a very detailed tutorial on how to design/implement/train NNUE from scratch -
unfortunately there's a abyss gap on this question - those smart enough just doing their own networks
while noobs are doomed to HCE. For me this is discrimination.
I would've definitely create a youtube tutorial on NNUE from scratch if only I was smart enough(((

Hi Daniel,

a good start point with a new motivation!
Better is to develops an own net and maybe your site will be again available.

I am very happy that you are back.

If you create a new website, I have a Andscacs collection for you :-)
You can add a link to my site or you can add your own versions (the collection by Andscacs lovers) on your own site.
In this case I will delete the *.zp file from my site ... of course, your decision.

Go Andscacs go ...
Great engine, great playing style and the programmer is back ... great news!

Best for you
Frank

You went from 2100 to 2900. He went from 3200 to 3450 (approximately).

Oh... Should've checked the rating firsts...
In this case very very impressive.

I was curious about what could I obtain adding nnue to Andscacs.
I went straight to nnue probe of Daniel Shawul:
https://github.com/dshawul/nnue-probe
After some work, manual tuning and testing, the result was beyond my expectations:

Code: Select all

50+0.5 
   # PLAYER              : RATING  ERROR   POINTS  PLAYED    (%)
   1 Andscacs 0.95183    : 3042.4   14.5    620.0     695   89.2%
   2 Andscacs 0.95143    : 2669.6   14.5     75.0     695   10.8%
So more than 350 elo in self play!

Here the Windows executable and latest Stockfish nnue net:
https://1drv.ms/u/s!Aj8wlSmr_Hq3islynT1 ... Q?e=FVH5CN
You can change the nnue net, just overwrite the nn.bin file.

Of course rating lists that care about engine originality should not add this version.
This is not only a dreaded disease, it is stupidity at its very highest leve.
Please explain to me how letting a bunch of engines mindlessly pound away at each other and writing out a bunch of numbers that nobody even knows exactly what they are expresses originality.

In the first place, it is well demonstrated in copyright law that a table of numbers (e.g. an NN net) does not represent originality and cannot be copyrighted.

In the second place, the humans are adding no additional originality whatsoever. It is like there are a million little workers all smashing a block of marble into dust and at the end, someone says that they invented dust.

I see very little originality in any of this, and yet it is being used as an excuse to exclude bands of people and engines from tournaments.
I guess they did not copy as quickly as the others who are accepted.

The chess community can have their phony-baloney "This is my original stuff and you had better not touch it" mentality. i find it very tiring,

Do not get me wrong. It is a lot of work to write LC0. It is a lot of work to graft NNUE onto SF. It is a lot of work to run a million trials to make a net.
It is just that there is no originality in it whatsoever.
Is a bit far from Stockfish, but is not bad:

Code: Select all

500+2
   # PLAYER              : RATING  ERROR   POINTS  PLAYED    (%)
   1 Stockfish 311220    : 2961.6   20.8     83.5     109   76.6%
   2 Andscacs 0.95183    : 2750.4   20.8     25.5     109   23.4%
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
