Leela is back!!

In the last 3 months, there was quite stall in Leela rating. However, with new training from scratch again in new test server, 20x256 net become the strongest version among all versions of leela ( +25 elo than 3 months ago). Approx elo of leela on 1060 GTX =3200 elo to 1080Ti =3300 elo, in comparision to  4 cpu, 3500 CCRL ,stockfish.

 

Most amazing thing is that, the Tensor Board data in training net has stable accurancy of policy net as 71%. That means, leela's first predicted move without any calculation is up to 71% accurate in comparision with the final move after calculation. null

ASM is the same stockfish code rewritten on assembly language, faster language, (Stockfish is written in C++)

Brainfish is stockfish+ Cerebellum (opening book)

So, ASM brainfish is combo of those two, it is custom build Stockfish by programmers.

Leela fans are happy to share recent amazing progress of Leela. In the last week, Leela gained about +100 elo securing the top 10 position in decent GPU hardwares (like GTX 1060) and possibly 4th best engine in GPU favoured hardwares(like GTX 1080Ti ). With TCEC hardware conditions, Leela should be between 4th and 6th position though.

+170 elo upgraded next version of Leela is ready for the next challenging stage 3. Leela could be -200 elo below stockfish now in TCEC  hardware and setting!

Elroch

The fish should be worried.

GO! Leela!

Does 'she' now identify as a 'man'?

I'll take LCZero seriously when demands are met....such as that horrible tactical score supporters keep ignoring. DeusX was better on positional too...thats embarrassing for Leela team.

Elroch

I think results are everything. If Leela wants to win tactical problem solving competitions, it needs to be trained differently.

I am biased though: I am not great tactically without an analysis board and a generous allocation of time.

Armstrong-s-a

Unfortunate that Leela could not qualify for the Division 2, though she finished 2nd, based on the tiebreaker score! Hopefully, Leela will be able to win the TCEC season 14!
