Lc0 vs 1# pos BT-2630

[hammerklavier]

Hi Friends! ,
[d]rq2r1k1/5pp1/p7/4bNP1/1p2P2P/5Q2/PP4K1/5R1R w - - 0 1

This is strange. Leela cannot found Nxg7 ???

I use leela in CPU mode, maybe some friend can help me with the analysis in a power GPU.


Thanks to everyone!

This is strange. Leela cannot found Nxg7 ???

I use leela in CPU mode, maybe some friend can help me with the analysis in a power GPU.


Thanks to everyone!

What network did you choose?

Bad-gyal-5 needs 4 seconds - also on cpu - and less than 1000 nodes.

Thanks Friends! I used 11258-48x5-se, but now change to 42850 and found in 20 sec....

What network recommend in a old cpu (Pentium E2200 2,2Ghz)?

Thanks !

You know, that depends on what you want to do.

Anyway, I would go for a small net (128x10 or less). E.g bad-gyal-5 or something like 11258-96x8-se and follow the evolution of the new 56-net.

Maybe an used Nvidia GTX 10xx GPU could be an option for an old pc too? But I'm no expert here; living in the mac diaspora

[Nay Lin Tun]

This is my Lc0 on my Samsung S10 with Little Demon 2 net on android Leela.
Leela see 1. Nxg7 within 15 seconds and stick with it.

Note. She found it around 4.5k nodes. It means, 1060 GTX will find in 2 seconds and 20xx RTX GPUs will find in 1 second.

Max how can you group 56-net? When i seek for a network in lc0 official site i see all networks stirred. Can you explain?

[Nay Lin Tun]

I suggest Little Demon 2, 10x128 net.
https://lc0.org/ld2

There could be other better smaller nets ( only minimal) , LD2 is the one officially using in TCEC and CCC .

Did you click on the 56-net link above? It should lead you direct to official run 2, where these networks are published.
