Leela Zero Cpu rating?

Post by h1a8 » Fri Mar 06, 2020 2:51 pm

1. Are there any rating lists that shows how strong Leela Zero is (cpu version) on various hardware? I have an i7 10510u laptop with 16gb ram.

2. Is the formula about doubling the nps to give about 60 elo still valid with the cpu version of Leela?


3. Which net files can I use for Leela to get 1700-2000 elo play? I want to play against a Leela about that strength.

http://www.fastgm.de

60 sec + 0.6 sec
10 min + 6 sec
60 min + 15 sec

are three cpu rating lists with Leela Zero cpu versions.

Ah, now the hard bit. All of the nets mentioned above are way stronger than what you require. There are basically two ways of weakening lc0 (the engine that uses the networks):

1. Use a small or minimally trained network
2. Reduce the size of the search tree
3. Both of the above

Unlike crippled ab engines which basically play like a drunk GM, some of these small nets on limited nodes can play a very entertaining brand of chess.

You can try out two small nets on limited nodes playing at lichess here:
The first is a 32x4 net (typically cpu nets are 128x10, gpu 256x20 or larger) running on a raspberry pi 3. It’s pretty strong for a human and may be stronger than what you require. The second is a 16x2 net distilled from the old t10 nets. It may be around 2200 lichess? They were trained from different data and should have a very different style from one another.

Anyhow, try those out and see where you end up.

A recent game that may give you a taste. I think it’s looking at 4000 nodes, which even on cpu is instant.

Can these nets be downloaded?

Looking at these, it’s not clear which networks are used. The 32930 and 11258 nets themselves would be terrible on cpu. Are these distilled networks?
