Re: Funny contraption

I'm even more impressed by this design for self-moving pieces: https://regiumchess.com/ Honestly, once I saw how it was implemented (a 3x3 grid of small, strong electromagnets under each square and captured piece area), I was amazed that nobody had tried it before. The mechanism is practically solid...

Re: another hard position (mate in 18) from 1998, by Ed Shröder

Spark 1.0 gets it in a few seconds at depth 16. It is a better than average mate finder.

Re: New DeepMind paper [MuZero]

I can't believe the whole forum isn't a-buzz about this! The new algorithm MuZero is extending the zero knowledge concept by not even pre-programming the rules of the game! It is building the model from scratch based solely on board state transitions and expected rewards. All it is retaining is the ...

Re: Shogi Perft numbers

I've never concerned myself with perft in my game programs before, but is it supposed to detect checkmates in order to avoid playing past fools mates? I was wondering if perft 7 could be used to enumerate all the shortest mates in shogi. There are 29 mate positions at depth 7 : nodes = 15 086 269 6...

Re: We lost our Pal

I remember being impressed that an engine "discovered" the Benko Gambit in one of the bookless or 4-ply book TCEC sections, but I can't for the life of me remember which season and section that was. If anyone has the TCEC archives downloaded, I'd be grateful for a reminder.

Re: Komodo vs. Larry K on chess.com

I have some chances. Look for games of "playkomodo" vs " Hissha " (that's me). Thanks for your valiant effort! Your handle (Shogi rook) reminded me that you are also likely one of the more knowledgeable folks on the recent strength improvements in computer shogi. When do you think the shogi program...

Re: Congrats the Komodo Team

I don't think the biggest share of the success goes to 8 x Intel (R) Xeon(R) Platinum 8168 CPU @ 2.7 GHz, 128 cores. Because Jonny plays with 1200 cores (60 x 20 cores Intel Xeon E5-2630 @ 2.4 Ghz) but it has only 4.5 points at 9 game. Thanks for those details. Are the platforms for the other four ...

Re: WCCC 2019 Macau..

Well, I think I might agree with Ovyron, which is scary by itself. Why not require that each team must create a robot to act as its operator? Seems more in the spirit of a computer chess event than relying on some specially trained human operator. This event seems like it belongs in another era ......
