LC0 autoconfigure would be nice.

It would be very nice if LC0 could look at your system and configure itself for optimal performance, or its best guess as to what that is.

[MOBMAT]

It has so many, I'm afraid to touch them.

You can expect this from a big video game but from a some kB chess engine this is an absolute unreal expectation.
Btw. There is only one AB engine what can do it.
I do not know only one either.

You can expect this from a big video game but from a some kB chess engine this is an absolute unreal expectation.

Why? It looks straight-forward. The engine could also take a look at the time control and adjust her own settings to perform better.

What may be unreal is expecting someone to devote time to it, but that's a different subject.

I've just given up and am going for defaults at home. I don't think it would ever be worth the time to figure them all out, and optimize them, rather than just running my analyses longer.

For the CCC (where they're trying to squeeze out maximum strength), we have

Which, what user will even know what MaxOutOfOrderEvalsFactor is? I sure don't.
