Re: Leela endgame training?

Today I've found that the Leela opencl (network=31269, apparently very recent) running on a GPU has serious trouble winning the most basic K+Q vs Q ending. It plays in a completely aimless manner, despite having access to syzygy TBs! But does it look better or worse at endings than networks 1xxxx a...

Re: Houston: We have lift off ...

“They” see “themselves” doing a “community” effort, but “you” see “them”, an “in-group” in which “you” are not “in”, but “you” hope “they” will do whatever and so on. Herein lies the problem. Groups have positive but also negative aspects. Something has gone wrong (in the sense that the inexorable ...

Re: Houston: We have lift off ...

Not abandoned, but put on lower priority. 30xxx is of course no longer "zero", so 20xxx is important if we care about being zero. sorry for being boring, and I ought really to know, but I don’t read much the AZ Discord chat. What aspects of 30xxx are no longer Zero? From discord: Tilps Yesterday at...

Leela ID 31252, engine version 19.4, can reproduce Alpha Zero move, 21. Bg5!! at 15 secs, 26k nodes in my GTX 1060 GPU.
Did you try other Leela IDs? Maybe many 1xxxx and 2xxxx IDs are able to find that.

Re: Houston: We have lift off ...

250 Elo points below 10xxx run with large 20x256 net. But these 20xxx and 30xxx runs with large nets run for months with only 100 Elo points better results than small net. 20xxx is IIRC already abandoned after several LR droppings Not abandoned, but put on lower priority. 30xxx is of course no long...

Re: Comparing Leela Chess Zero with AlphaZero

My point of view: 1) All these tests suggest that Lc0 is not so far from A0 as everyone thinks Depends which "everyone" you mean. There've been growing claims for many months now that Lc0 has already passed A0. e.g. one of the estimate lists has "Alpha Zero 1080Ti [No Handicaps] 3545" and a group o...

Re: Is Deep Blue source code open?

Custom hardware for chess is the wrong approach. Unless you want to be the first ever to beat the chess world champion and gain a ton of publicity, but we're too late for that. Now, if you've got a billion dollars and you're bored and happen to like chess a lot, then have at it. Just know that the ...

I am just wondering if IBM released the source code for Deep Blue, I see no reason why they wouldn't.
I can see a reason why they wouldn't. Someone could translate it and then we'd all see just how weak it is as software.

Which network ID is being used for the current chess.com CCCC? I can't see this info on chess.com.
Which ID was used for the TCEC Cup?

Re: Chess Engines with Opening Book

The Cerebellum book used by Brainfish is external. It is not part of the executable. It is just an advanced book made by mini-maxing a huge pile of chess data. It is a more sophisticated format than polyglot books (and the data is better than most polyglot books), but I still consider it to be rath...
