Hidden lc0 parameters

[Eduard]

Can someone explain why these options are not visible (For example in the Fritz GUI)?

--time-midpoint-move TimeMidpointMove

"The move where the time budgeting algorithm guesses half of all games to be completed by. Half of the time allocated for the first move is allocated at approximately this move.
Default value: 51.50
Minimum value: 1.00
Maximum value: 100.00"

--time-steepness
TimeSteepness

"Steepness" of the function the time budgeting algorithm uses to consider when games are completed. Lower values leave more time for the endgame, higher values use more time for each move before the midpoint.
Default value: 7.00
Minimum value: 1.00
Maximum value: 100.00"

The entries are accepted from lc0.config, is that correct?

Interesting. Thanks for sharing this info Eduard. I think I will test Time Steepness at 4.00 or 5.00

I played 7 games 16+0 on Playchess (I play with the 6men and many 7men Syzygy). Best setting today was:

--time-midpoint-move=46.50
--time-steepness=15.00

Slow Mover was 0.8
and Move Overhead 75000

My GPU was only a GTX 1050 Ti.

Leelafish with sergio 256x20 played great games, 6x draw 1x won!

I like the Leelafish, please new version!

I forgot to say, I set the nncache in the lc0.config to:
--nncache=2000000
