Re: Lc0 with two Networks?

It's possible to switch network file between moves in Lc0 with uci parameter. However it's not currently possible to use several networks within one search (e.g. depending on depth or number of pieces). But won't that suffer from Evaluation Discontinuity ? Yes, it suffer from it. But if you use net...

Re: stockfish 10 vs. Mephisto III S Glasgow

There is no any obstacle to built in the elements of the evaluation of Mephistos engine into the source of Stockfish. But if there is somebody who think such a "Stockfish" would be stronger than the up to date Stockfish is that person is very wrong. Obviously running on the same machine this "Stockf...

Re: Time per gigatype RAM with NN engines to exhaustion

Most ssd devices have about the same endurance as a regular mechanical disk. Very curious statement, to say the least ! Basis ? From what I have read, ssd failure after too many writes is intrinsic to ssd... Every SSD have a self-repair tool. This tool marks the bad cells and the control of SSD can...

Re: Time per gigatype RAM with NN engines to exhaustion

LC0 is still WIP, make an proposal on GitHub or Discord. Afaik Percival (dragontamer) came up with this idea too. I believe it is possible to do a MCTS traversal with virtual-loss on the hard drive or SSDs, but I haven't fully discussed with anyone the full scope of my idea yet. I'm kind of busy wi...

Re: stockfish 10 vs. Mephisto III S Glasgow

In the time of Mephistos (I have the Lyon 16 bits with about 2100 Elo against humans) the fast engines called "bean counter". Now we call Stockfish. But what a difference is! In every times the main task of the developers is to find the balance among chess power, methods of position evaluation and s...

I already have one, but I might buy another one of these:

I saw that the motherboard can handle it.
If you would buy a common SSD and connect to a SATA driver it would be good too.

Re: Time per gigatype RAM with NN engines to exhaustion

NN engines do not need fast working memory/page file.
So if you set up a big (50-100 GB or more GB) page file on a HDD it may be appropriate.
Obviously if you use SSD instead of HDD it will be better.

Re: The optimalized Fat Fritz

... I do have tests that show FF stronger than Test40 quite clearly, but the catch is that I tested in default lc0 settings for both. I will revisit my settings and a longer tune with no assumptions and see what comes. As to the result I mentioned, just for transparency: Score of FF v281 vs lc0-v22...

Re: Leela version 0.23.0 for download

... Where from you get the "BUILD IDENTIFIER" what lacks from source? Maybe from Github? In the ..\neural\encoder.cc there is a "switcher" function in which the second branch (case....::INPUT_112_WITH_CASTLING_PLANE:....) has no any connection and it is defective. What is the task of it?

Re: Leela version 0.23.0 for download

... Did you regenerate your .sln file using build-cuda.cmd ? There are files added and removed between releases, and some of build options change too, so it's not possible to just copy new files over and use the same generated build config. You can fetch project into a fresh directory and run build...
