Re: ChessDBCN

Hello, This is a great tool! I'm trying to do tools around it and i found something odd, nodes above 50 move rule: https://www.chessdb.cn/cdb.php?action=queryall&board=2rr1bk1/pb3pp1/4qn1p/2pp4/8/1P2P1PP/PBQN1PBK/2R1R3%20b%20-%20-%20258%20159 It ignores move counters entirely and rules may be handl...

Re: My failed attempt to change TCEC NN clone rules

So to summarize, it's a story of how two dictators pretending to be open to opinions while one suggests the other shouldn't and the other suggesting to keep it up.

P.S. I was also told that I get to decide many things but in fact my opinion doesn't matter, either. :D

Re: ChessDBCN

Agreed. You specially want to feed it stuff and come back after a few hours, it's a kind of live database powered by AI, you need to let it chew in the positions so the bad lines fall to the bottom of the ranking. What I found curious is that back when I started using it, the DB size was already at...

Re: ChessDBCN

Very nice work. Could you tell a bit more about the 'large cluster' which runs the analysis engine? Also which version of SF is used and will it change with time? There are two queues: one is for move exploration, each position is evaluated by a shallow SF search on multi-PV(depth 12), sieving from...

ChessDBCN

There has been a few threads and related discussions about my work on chess, now it has came to some fruition. I have built and documented unified APIs for both chess and Xiangqi, with probing interfaces to demonstrate their usage. https://www.chessdb.cn/queryc_en/ The APIs will provide online posit...

Re: Google "DeepMind" AI Chief Placed On Leave..

Isn't it ironic that our world leading AI company is having problems with overpriced human laboring?

Re: What the heck happens here?

It's quite straightforward: The learning target of those NNs are to fit the outcomes of a one-node evaluation to a multi-node search. In essence, they don't learn chess, they learn how to produce the most statistical fitting outcome of a defined way of search. In turn, with chess rules applied, this...

Re: Congrats the Komodo Team

I think I need to do some more programming to take advantage of an 8 NUMA node machine. All those cores trying to access memory requires more speical memory management, so we will work on it. Komodo was getting about 70-90 million nps for much of the positions, but faster in endgames. With some wor...

Re: Stockfish Wins Chess Com Engines Champs9!

I have heard that hand-crafted evaluation functions are a way of the past and had introduced bias beyond redemption.

Re: Congrats the Komodo Team

While the rest of the cores on the machine were probably kibitzing TCEC during the event. I think top tier teams should be strong enough to overcome those minor hardware differences. :D So Komodo was running on one of your machines? The one that gave 431.403.814 nps for asmfish? http://www.ipmanche...
