Re: Is Carlsen's approach similar to that of AlphaZero?

I don't think humans incorrectly project "understanding" to a NN. I think it's more like we have different definitions of what to understand means. In what sense does a human understand anything? It's just chemical reactions that are happening in the "calculation machine" that is the human brain. Th...

Re: Is Carlsen's approach similar to that of AlphaZero?

I have not looked at a thread here. Though I wouldn't be surprised if there were similar discussions in the forums here. As for network size, yes that is true of course. I was talking about the number of nodes calculated which would be a typical measure of brute force vs knowledge. Of course you can...

Re: Is Carlsen's approach similar to that of AlphaZero?

A0 is just using brute calculational force. This simple fact is somehow swept aside by all the propaganda. (We also do not have access to all of A0's games.) Carlsen has deep understanding. Engines of any kind have brute calculating power. While that is true of course, it uses that power for a very...

Re: Efficient capture generation in the game of Thud

Note that for such big boards entirely incremental methods are often very competitive. You could for instance keep an attack map for the Trolls, 8 bit per Troll, to indicate from which of the 8 directions they are attacked. This packs nicely into a 64-bit word, so you can 'generate' the captures of...

Efficient capture generation in the game of Thud

Before I start, sorry if this is too offtopic, it's not directly related to chess though I can't think of better people to answer this than chess programmers. Thud is a board game played on an octagonal 15x15 board. (for implementation purposes it might be useful to consider it as square and just ne...

Re: Chess Fighter Neural Net

Been playing games online? Show me how! Chess Fighter would love to play online :D . Seriously, Chess Fighter has not played online and I don't (yet) know how to implement that kind of stuff. Though I hope to get some help through this forum. You can make a bot account on lichess and run your engin...

Re: stockfish 10 vs. Mephisto III S Glasgow

If we're doing strange fixed nodes testing, then why not put Leela vs Mephisto at 1000 nodes. Surely that will be close. (I predict Leela will score 100-0 in a hundred game match) Obviously if your node contains much more calculations your engine will be stronger at fixed node count. Instead it sho...

Re: stockfish 10 vs. Mephisto III S Glasgow

As for progress in engine software, nice reddit post: https://www.reddit.com/r/chess/comments/76cwz4/15_years_of_chess_engine_development/ So you're saying that Mephisto had low nps despite other engines having way higher nps at the time? So essentially it just does way more in it's nodes, that's li...

Re: Swiss Tournament. Edition VIII. Group F.

I wanted to send a new version. Oh well, next tournament. :D But very nice start 2.5/4 against much higher rated opponents. (probably just variance, but still nice) On a side note, the pgn for my engine seems to be broken, not a huge deal though. Fantastic :) I can test it anyway I must see the pgn...
