Leela Chess Zero Blog
TCEC Cup continues and we already know 6 engines that have promoted to next
round.
Leela right now has a big fight with Laser and after 4 games it is on 2-2 with
4 draws.
The TCEC Cup has started and 2 match pairs will be played every day.
We remind that 32 engines will compete in a Knockout elimination tournament,
and in each pair match, the best out of 8 games will promote to next round.
That means if an engine completes first, in the 8 games, 4.5 points will
promote. As per their decision if an engine completes first 4.5 or 5
points , the match is stopped and the engine promotes to next round. So not
all 8 games will be played if not necessary.
Also the tournament would not necessarily be continuous like normal TCEC,
since only **2 pairs will be played every day **even if there is time for
more. The games will begin 12:30 UTC every day.
Leela won 16-14 against Komodo the 30 games match to determine 3rd position in CCCC1, while on the variants tournament she won a game against Stockfish while being handicapped having a Pawn less!!
It turned out that the version v0.18.0, that was released a few days ago, had a bug that caused it to miss tablebase wins sometimes.
Because of that, v0.18.1 is released. You can download it here.
Deepmind’s latest paper release ( Mastering Chess and Shogi by Self-Play with a General Reinforcement Learning Algorithm ) on 5 December 2017, presented a method of reinforcement learning for convolutional neural networks that its result was fantastic as they created 3 engines, one for GO, one for Chess and one for Shogi that were beating easily the best available engines of the time.
TCEC Cup is about to start in a few days and Chessdom.com just announced the complete pairings up to the final.
Leela is on the Stockfish side and if she will promote from the first match
against Laser she will probably face Ethereal in round of 16, so it will be a
tough match already.
But first has to overcome Laser of course.
Leela in TCEC Cup will use the v18 of Lc0 and 11248 net of
test10.
v0.18.0 is out of “release candidate” status, and now is fully released!
Can be downloaded here.
It has no changes relative to RC2. For the list of differences relative to v0.17, see posts for [v0.18.0-rc1](../../../2018/09/lc0-v0180-rc1-has-been- released.html) and [v0.18.0-rc2](../../../2018/09/lc0-v0180-rc2-has-been- released.html).
The TCEC(Top Chess Engine Championship) tournament is currently running with
engines playing in the premier division and this division will finish in a few
days. But this time, after premier division end, there would not be an
immediate starting of the superfinal between the top 2 placed engines in
premier, but a new tournament is going to happen that Chessdom has
announced, the TCEC
CUP , with all engines of TCEC but in a different format, that of knockout
games, one that brings in mind the traditional Cup competitions of football.
(TCEC superfinal will he held after the TCEC Cup of course)
Chess.com has [announced](https://www.chess.com/news/view/stockfish-houdini-
to-battle-for-computer-chess-championship-komodo-vs-lc0-for-3rd) that after
the CCCC superfinal between Stockfish and Houdini(Stockfish is ahead 27.5-20.5
till now) will finish, then 30 games of Komodo versus Leela will be played
to determine the 3rd place.
This is a surprise since there were no such plans initially announced, but it
is welcomed for Leela and Komodo fans. Probably Chess.com did it since Leela
fan base is high and they want to take advantage of this.
The “Release Candidate 2” for the Lc0 version v0.18 has been published!
