Re: Alphazero news

@ Matthew One thing I never understood from the original match was why SF8 had hash set to 1 GB. This may raise nps, but it surely lowered strength. Also the decision to have HT on was questionable. What were the reasons for this? We set it to 1GB in the very beginning because we wanted to play man...

Re: Alphazero news

Yes, the same 12. The openings the most commonly played openings from a large set of high level human games (I don't remember which set off the top of my head). There is no cherry-picking. They were the top 12. If they favour AZ, that just means AZ plays common human openings better. Yes, the score...

Re: Alphazero news

If you don't like that 4-mover suite, allow SF8 or SF9 whatever to use a diversified polyglot book, with A0 playing its best moves right from the start . ANyrhing against that? If we did that, the criticism we would be getting now would be something like "those books aren't very strong, and SF woul...

Re: Alphazero news

Sounds like a very reasonable explanation. But "being good" seems to be an attribute of a position that appears to be much more subjective than I thought. BF is playing the book-resulting positions successfully against a non-book SF, that its purpose, the reason why it exists. This superiority is, ...

Re: Alphazero news

Matthew, I have one last question regarding the implementation details that aren't explicit in the paper. Normally, an MCTS search would do "tree reuse" from move to move, carrying forward the subtree that was actually chosen. But during the training, there is noise added to the root. If one does t...

Re: Alphazero news

Conferences are even worse, just look at NIPS or E(I)CCV, acceptance rate is like 20% and if you are from Google acceptance rate goes to 70-80%. And they submit papers of equal quality? I don't know about Google, but we only submit paper that we are pretty sure will be accepted. We don't submit the...

Re: Alphazero news

It's hard to say and I don't want to speculate much beyond what we have data to support, but my guess (and I can very well be wrong) is that there's much less diversity when SF uses the BF opening book. That is correct. When playing with the default settings (one of the default options is BestBookM...

Re: Alphazero news

Matthew, thank you very much for participating in this thread! Everyone here should be grateful, that we are now getting the answers that were missing so much after releasing of the preliminary paper last December. Let's keep this discussion a technical one. With regards to this, I have a question,...
