Hi
To what extent does NNUE enabled affect personality settings (parameters)? I noticed you tested Rebel 14.1.2 CSTAl with NNUE but you changed parameters, Also if using Shaschess personality settings such as TAl (Shashin theory?) does that mean NNUE should not be enabled? I dont remember reading that anywhere, I am just wondering? Thanks
If I understand correctly when NNUE is enabled the network dictates the evaluation values.
In other hand if you want to tweak or rather modify some parts of the evaluation you need to disable the NNUE or if you want to be more technical set it to use regular evaluation. From what I understand personalities are just modified parameters that affect the evaluation, correct me if I am wrong.
I read about this on Komodo website, as mr.Pohl mentioned in his reply the Komodo team has automatic function that switches to regular evaluation whenever there is selected non-default personality for Dragon.

Yes, I also thought about NNUE evaluation as you do. Just that I noticed you tested CSTAL 14,1 , with I think NNUE enabled, but you also changed the parameters? (Although I notice CSTAl 14,1 uses a NNUE Tuner, which might explain why parameters can be effectively changed?

Also, I wondered if the personality settings (shasin theory?) with Shashchess should be enabled with or without NNUE? Perhaps my assumptions about those parameters and shashin application are incorrect,

Anyway, Thanks for releasing your findings and parameters regarding aggressive engines. Interesting.

ShashChess24 High Tal is weaker in all categories: Less sacrifices, less short wins, more bad draws than Stockfish 15...
So, a testrun for my SPCC-ratinglist does not make sense for me...
Now this I find very interesting, did you make sure to disable NNUE on ShashChess24? My apologies for never mentioning it but with engines that make use of NNUE (such as Dragon, ShashChess) this feature need to be disabled in order for the "personality" to take over.
Other than that I have nothing to add, I am in pure disbelief to see SF 15 be more aggressive than ShashChess with HighTal personality.
Oh. No, I did not disable the nnue-net. My bad (but for my excuse: KomodoDragon switches the net off automatically, if "aggressive" is chosen). I will retry. But then ShashChess will be much weaker. So, vs. SF 15 makes no sense. I will try Stockfish final HCE as opponent.

Stockfish final HCE was too strong, so I used Rebel 15.1a as opponent. ShashChess HighTal was around +40 Elo stronger. 3500 games (singlethread 60sec+600ms, balanced Feobos openings)
Here the result of my EAS-Tool:

We see a change here (with nnue off): The number of short wins is extremly high, now. Thats good. But, sadly, the number of played sacrifices of Shash is very low, which is definitly no "Tal-style". And the number of bad (=early) draws is very high - bad, too.
In combination, these 3 parameters give an EAS-score, which is nearly equal to Rebel 15.1a. Thats OK, but definitly not overwhelming. If you look in my EAS-Ratinglist, Rebel 15.1a is on rank 16 and far behind (points!) the really aggressive playing engines (Velvet 4.1.0, Danasah 9, KomodoDragon aggressive-setting...).
Perhaps, I will try ShashChess HighTal in my SPCC-ratinglist, but I do not expect a really good EAS-ratinglist result for this setting...

Below is my top 20 using EAS and note another one to consider is Stockfish 5 Fury which is also based on modified settings via UCI settings.

CSTal (#11) is Chris's work.

Each engine played several thousand games.

Code: Select all

***************************************************************************** 
*** Engine Aggressiveness Tool V4.1 Score points Ratinglist 
***************************************************************************** 
Score is: (percent*100) of the percent-values of the sacs (1-5+ pawnunits) 
calculated out of the won games by the engine, only. 
So, a weak engine (with a small number of won games) can get 
a high EAS-scoring, too, when the percent of sac-games in the won games 
is high (and the number of short wins). Higher pawnunits-sacs give bonus-points: 
1 pawnsac = 2x points  *** 2 pawnsac  = 10x points *** 3 pawnsac = 20x points 
4 pawnsac = 40x points *** 5+ pawnsac = 80x points *** 5+ Queensac = 150x points 
Additionally, very short won games (percent*100) give bonus-points. If the short 
games ended before endgame (a check for low material is done), then these points 
are quadrupled (4x): 
60 moves= 1x points *** 55 moves= 2x points *** 50 moves= 5x points
45 moves= 10x points *** 40 moves= 30x points.  
Since V4.1, the tool also searches for "bad draws" and adds points for the good 
draws ((percent of good draws (out of all draws)) exp3 /15) 
Bad draws are games, which were drawn before endgame was reached (except the 
games, were the engine had a material disadvantage) and draws 
after the engine had a material advantage of at least 1 pawn in the game.

This is also a very good list. Most of the names ring true for their aggressive playing style. I hope you have tested engine called Disaster Area too? It does play exceedingly aggressive only when it is fed with those parameters sharted above. Otherwise, I am not very sure how it does with the standard values.

I have now tested DisasterAres 1.65 with its default settings. 50th on my list on EAS score.

Below is my top 20 using EAS and note another one to consider is Stockfish 5 Fury which is also based on modified settings via UCI settings.

CSTal (#11) is Chris's work.

Each engine played several thousand games.

Code: Select all

***************************************************************************** 
*** Engine Aggressiveness Tool V4.1 Score points Ratinglist 
***************************************************************************** 
Score is: (percent*100) of the percent-values of the sacs (1-5+ pawnunits) 
calculated out of the won games by the engine, only. 
So, a weak engine (with a small number of won games) can get 
a high EAS-scoring, too, when the percent of sac-games in the won games 
is high (and the number of short wins). Higher pawnunits-sacs give bonus-points: 
1 pawnsac = 2x points  *** 2 pawnsac  = 10x points *** 3 pawnsac = 20x points 
4 pawnsac = 40x points *** 5+ pawnsac = 80x points *** 5+ Queensac = 150x points 
Additionally, very short won games (percent*100) give bonus-points. If the short 
games ended before endgame (a check for low material is done), then these points 
are quadrupled (4x): 
60 moves= 1x points *** 55 moves= 2x points *** 50 moves= 5x points
45 moves= 10x points *** 40 moves= 30x points.  
Since V4.1, the tool also searches for "bad draws" and adds points for the good 
draws ((percent of good draws (out of all draws)) exp3 /15) 
Bad draws are games, which were drawn before endgame was reached (except the 
games, were the engine had a material disadvantage) and draws 
after the engine had a material advantage of at least 1 pawn in the game.

This is also a very good list. Most of the names ring true for their aggressive playing style. I hope you have tested engine called Disaster Area too? It does play exceedingly aggressive only when it is fed with those parameters sharted above. Otherwise, I am not very sure how it does with the standard values.

I have now tested DisasterAres 1.65 with its default settings. 50th on my list on EAS score.

Code: Select all

***************************************************************************** 
*** Engine Aggressiveness Tool V4.1 Score points Ratinglist 
***************************************************************************** 
Score is: (percent*100) of the percent-values of the sacs (1-5+ pawnunits) 
calculated out of the won games by the engine, only. 
So, a weak engine (with a small number of won games) can get 
a high EAS-scoring, too, when the percent of sac-games in the won games 
is high (and the number of short wins). Higher pawnunits-sacs give bonus-points: 
1 pawnsac = 2x points  *** 2 pawnsac  = 10x points *** 3 pawnsac = 20x points 
4 pawnsac = 40x points *** 5+ pawnsac = 80x points *** 5+ Queensac = 150x points 
Additionally, very short won games (percent*100) give bonus-points. If the short 
games ended before endgame (a check for low material is done), then these points 
are quadrupled (4x): 
60 moves= 1x points *** 55 moves= 2x points *** 50 moves= 5x points
45 moves= 10x points *** 40 moves= 30x points.  
Since V4.1, the tool also searches for "bad draws" and adds points for the good 
draws ((percent of good draws (out of all draws)) exp3 /15) 
Bad draws are games, which were drawn before endgame was reached (except the 
games, were the engine had a material disadvantage) and draws 
after the engine had a material advantage of at least 1 pawn in the game.

Thanks for testing and good to see many of lower rated engines tested for its ability to play aggressively. However, Disaster area engine plays very aggressively with the following parameters, which was shared earlier.

These are the settings of the selected "Gambit suicidal" personality, keep in mind it is experimental and will make Rodent play weaker but more aggressive

http://www.pkoziol.cal24.pl/rodent/rodent.htm

Opental is a derivative of Rodent. And Opental is the most aggressive engine on the planet. But only around 2300 Elo.
Latest version on my Google Drive as I posted here before:

By the way: Using the polyglot-adapter, I made a version of OpenTal 1.2, which runs in FritzGUI (normal version does not!):

(You must change number of Threads (I set it to 8 (8 is the highest possible!)) and Hash in the polyglot.ini-file (both parameters are at the end of the ini-file)). The polyglot-adapter was renamed to OpenTal_1.2_x64.exe (use this file for Create UCI engine in Fritz GUI, not "enginebinary.exe" (!!!))

I other GUIs, you can use Opental without adapter. Just rename enginebinary.exe to Opental1.2 or so. And use this file in the GUI.
