Re: kiwipete perft position

That's an interesting position. My freshly implemented perft worked for all positions on the cpw except this one where on perft 4 it gave exactly 4 nodes too many which seemed like an oddly small number to be off. As it turns out I somehow didn't clear e.p. rights when castling which gave the exact ...

Re: Search-based opening book

Not sure if this has been suggested like that before, but I just had an idea for book creation without a large set of games behind it already. Thinking about it further it is actually somewhat similar to Leela's search so I might as well describe it as such. So in the book creation step you basicall...

Re: Human odds games

A friend of mine was asking whether there have been serious attempts to find good handicaps for various rating differences. In engine games there seems to be some rough understanding of it, however what about human vs human games? Maybe @lkaufman has some insights? Yes, I know a lot about that topi...

Re: CCRL 40/40, 40/4 and FRC lists updated (10th August 2019)

Thanks for testing Koedem. Not very important, but with source code available https://github.com/koedem/Koedem/releases shouldn't both versions be listed as Open Source? :)

Re: Koedem 1.1.1 Release

Nice surprise, Kolja. As your warning may be forgotten or someone may miss your post, can you not change the release with that parameter set to 2000? Did change it now, hopefully I didn't break anything along the way... As for the improvement, at this level it still is rather easy to make big impro...

Koedem 1.1.1 Release

So I finally put my engine up on Github along with a release of version 1.1.1. https://github.com/koedem/Koedem/releases Would be happy if it got tested e.g. on CCRL, should be some 100-200 points stronger than version 1.0 there. Any opinions on which license to choose? I for now followed Stockfish'...

I guess with 128 TB RAM, approaches like MCTS, that store the game tree, will
start to make more sense than using it only for TT.
Well, Leela probably already is the strongest engine in the world, not too bad if you ask me.

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...
