Komodo 11.2

[peter]

The present Dynamism is not tied to a specific side. It inflates or deflates a number of dynamic parts of the eval, without changing the more static evaluation features. So it is symmetric.

Thanks for explaining, Mark!

In my opinion, Dynamism is best left at 80.
Anything more and Komodo just becomes over-ambitious and weak.
More Dynamism does nothing positive for Komodo, in my experience ; unless you are playing against a very weak player using a non-stockfish Engine.
Against Stockfish or its clones, more Dynamism is just plain Suicide !
You're better off fiddling with the other Parameters to improve ELO, leaving Dynamism at 80.
Upto you...

Do you play at a wide range of time controls? We have found sometimes best setting change based on the time control. So it would be interesting to see what you have used.

???Default Dynamism is 120, not 80.

???Default Dynamism is 120, not 80.

...in Komodo 11.2. Yes, I know that.
I never said that 80 was the Default Setting.
But I still say that 80 is the ideal Setting for Dynamism. Anything below or above is no good and is detrimental to Engine Performance.
Other Settings I'm not too sure of and as Mr Lefler says, may depend upon Time Controls used.

You said "left at 80", which implies that the default is 80. But never mind that. I'm working on Dynamism right now (coincidentally). 80 agrees more or less with my subjective opinion of what makes for sensible evals, but it clearly loses elo points in game play vs 120 (or even 130) at bullet or blitz levels. So my question to you is what time limit do you refer to in your statement, and is your opinion based on results, or on seeing poor moves, or on seeing questionable evals? It is also possible that the number of threads running makes a difference for Dynamism.

LK:
If my memory is correct, when Dynamism was first introduced, I was using about 93 for that parameter for very long time controls. This must have been based on your recommendation at the time.

Granted. My bad.
I usually play at 4'+2'' or 5'+1" on Infinity Chess or while Testing on Arena GUI. No time nowadays for my favorite LTC games.
Yes, my opinion is mostly based on results, but yes, sometimes I've observed that Komodo shows a over-optimistic evaluation which changes later.
Number of Threads is 8 because I use 8-Core Processors.
I've tried HT ON also, but using 12-14 Threads doesn't really seem to make a positive difference.

Anil V Dharan: tell me the reason for not using Fritz 15.

My impression is that Infinity Chess is an artificial version of Fritz.

.......I'd bet a lot of money on any match between 11.2 and Houdini 5 at any reasonable time control.
