Leela CPU becomes Top 5 engine

[Alayan]

Leelenstein is a Leela clone with a different net, not a different engine.

I guess you're thinking about Scorpio though.

How can you be sure it is a different net ? It took a lot of ressources to get so many goods nets for Leela.

Exist this new Leela CPU for android devices?

If yes please post a link.

Depending on android device and time control, you may need to consider smaller net. For my samsung S10, I get around 250 nps on T 59 10x128 net. So it is good enough for my game review/analysis (I use 10-60 seconds in some interesting positions ).

...that make Leela on top 5 engine behind Stockfish , Komodo and Houdini.

In CCC’s own championship both Komodo and Houdini finished outside the top 4.

Chess.com post is for quick reference. For cpu only engines, no doubt the big three are still on top.

Is there a net that sees the winner 40.Rad1 from yesterdays game of woman worldchampion Wenjun against Gunina under a minute?

My Samsung tab S5e can´t handle this net.

Maybe the size of 385.258 kb is to much.

The biggest net i run on this device has a size of 7.272 kb.

Or did i do something wrong?

[Nay Lin Tun]

This is analysis by T59 on my Samsung S10

1. Ra7 is the choice which is also completely winning.

Usually Leela dont see the shortest way of winning but she usually see her own way of winning.

[Nay Lin Tun]

Currently LC0 CPU is on par with Komodo 13+ (dev cersion).

Probably she can be on par with Stockfish in next year.

[Thomas Lagershausen]

A) Which net is recommended for CPU-Leela?

B) Is there a Benchmarklist for CPU´s for Leela?

C) How many nodes makes Leela on a 6 core Ryzen 3600?

Thx for your attention.
