Minic version 2

[xr_a_y]

Vivien, please enlighten me. If the NNUE used is not from SF but your own work why don't you want it to be tested?

NNUE merge was too easy
NNUE technology is from SF.
But yes I built my own net (nascent nutrient).

Please see this
http://talkchess.com/forum3/viewtopic.p ... fe#p863067

NNUE is no different than every single technique/technology used in chess (LMR, null move etc.) except that all of them are related to search. Is it something about NNUE being an eval-based technology that makes it undeserved to be recognized by you?

I not only borrow the technology, but also the code itself (a code bigger in number of lines than Minic code itself !).
Moreover NNUE merging inside Minic (both evaluation code and learning code) was very easy, because the code was already well cleaned by Stockfish contributors.

I get it if the used net to rank Minic is SF nets, but I don't quite get why you don't want to recognize your own homebrew nets that are created from Minic own eval as a part of Minic.

I guess I "recognize" that, I did the work for building that and generating the data. But I cannot have my engine rated with such a copy/paste of code ... Let the dust settle. Will see what will happen in some months ...

Gabor, that's an example why I don't want MinicNNUE (even with nascent nutrient) to be rated and been called Minic. Because there is good chance it will here between Ethereal, Xiphos, Defenchess, rofChade, ... I don't feel like it is its right place.

Another example is what is currently happening in Graham division 2 (with nascent nutrient also)

Code: Select all

   1.   MINIC 2.50 64-BIT                           34    21.0    **** ===. 101. 0=0. ===. 10=. 11=. ==1. 1=1. =1=1 1=0. 11=. 
   2.   DEFENCHESS 2.2 64-BIT                       34    20.0    ===. **** 1==. =0=. =1=. =1=. ==== 01=. =1=. ==1. ===. 11=. 
   3.   RUBICHESS 1.8 64-BIT                        34    19.0    010. 0==. **** 1=1. ===. 0==. =0=. 11=. 1=1. 1==. ===. ==1= 
   4.   ANDSCACS 0.95 64-BIT                        34    18.5    1=1. =1=. 0=0. **** ===. =1=0 =0=. =1=. 0=1. 11=. 0==. =1=. 
   5.   ARASAN 22.1 64-BIT                          33    18.0    ===. =0=. ===. ===. **** 11=. 10=. ==1. 01=. =1=. 10=. ===. 

In front of Defenchess, Rubi, Andsacs, Arasan, ... and on a quite small hardware I guess from the nps ... will be even worst on better hardware I think. So not me league ...

For now, I'm learning about NN and that's enough.

But then we might not test Minic in the foreseeable future. What if you disabled NNUE support in the released versions until you feel Minic NNUE is entirely yours?

Minic 2.51 without any net (thus not using NNUE code) is not tested yet at ccrl and is quite stronger than 2.46 or 2.33. You can test this I think?

Sure. Only, it is going to create a confusion about whether NNUE was used or not. We usually use defaults but the list does not show that.

On the other hand, if an engine is capable of using NNUE then it would seem odd to use it at a weaker setting. That's why I suggested disabling NNUE. Then the default setting would be the strongest one.

Thanks.

Hi, thanks for reporting. I am pretty sure that sure work. Something relative to path may be wrong. Easiest way to be sure is to put net in the same directory and just use its name as input.

2.48 has less logging about NNUE, I am not sure it loaded net in your example. Check if nps are small to be sure the net is loaded under 2.48.

[xr_a_y]

Minic 2.51 without any net (thus not using NNUE code) is not tested yet at ccrl and is quite stronger than 2.46 or 2.33. You can test this I think?

On the other hand, if an engine is capable of using NNUE then it would seem odd to use it at a weaker setting. That's why I suggested disabling NNUE. Then the default setting would be the strongest one.

I'd like it to be solved by the naming convention

Minic2.51 is minic standard eval
Minic2.51NNUE+nascent_nutrient is NNUE and we know the net being used

That is what CEGT will do and for me it is fine as MinicNNUE rating is not replacing Minic rating.

Hi

forceNNUE=true
will result in a full NNUE eval, and thus a slow down.
I highly recommand setting this too false to use "hybrid" evaluation (threshold is 600cp currently).

Sorry if it was unclear, i'll document that in the github page soon.
