Yes, yeah. The reviewers can be in disagreement. It happens. Depends how much the unhappy reviewer wants to fight.
That did not answer my question. How many Science papers did you publish that way?

Re: One billion random games

My tentative conclusion is that these random games have no reality value; I tried them from several positions with material imbalance, and it even fails to properly judge the value of those imbalances. For Queen, Rook and Knight odds the results reasonably match the classical piece values. But a Kni...

Re: Alphazero news

That is not true. It's definitely possible to get the paper accepted without reviewers all being happy. But the publication policies of Nature & Science probably shouldn't be the main topic here. Oh yeah? How many Science or Nature papers do you have to your name that did not have the approval of t...

Re: Alphazero news

Is it because people who wrote those 'fully decent' papers are not Google-branded? But in my view a 'decent paper' is still a decent paper even if it is published on a morning newspaper. Conspiracy theories are the hallmark of paranoia. You have to 'pass' 3 anonymous peer reviewers, and if only a s...

Re: fast(er) movegen

Not really a relevant example, though, as everything to do with Pawns you would normally get for free from the Pawn hash table, and the hit rate on that would be so hight that it is completely immaterial how much time you have to spend for calculating stuff when you have a miss.

Re: Alphazero news

You don't seem to have much experience with publishing papers in Science (the journal). My experience is that it is very difficult even to get 'fully decent' papers published there.

Re: fast(er) movegen

I just wrote a generator for random games, and I solved the legality problem there as follows: Basically it is just doing pseudo-legal move generation, before selecting one of the moves at random. It then just plays the move, and generates moves for the opponent. Which is the thing it would have to ...

Re: UCI2WB 4.0

As the only existing link to the file is in the forum post here, which also mentions where to find the source code, it is really hard to imagine how people that download it could not know that the source code is available, and where... I am not in favor of bundling things that people might want with...

Re: One billion random games

I did a follow-up on this old study, to answer some of the questions it raised. To this end I wrote my own random game generator. I took the short-cut of abolishing castling and e.p. capture; this did not have a significant effect on the statistics of the purely random play, and I could not imagine ...

HGM's move generation on qperft is a good reference for speed. If you want to change your board representation there is no doubt that bitboard representation is the fastest.
Actually I doubt that.
