Re: Polyglot - merge-book oddity

I would just print a warning on stderr that the behaviour of merge has changed. A good name for the old behaviour would be "update".

The help string and the man pages have to be updated too.

Re: Polyglot - merge-book oddity

I am just worried that folks who did not read this thread will use the new version without understanding the consequences, hence I gave it a different name, not Polyglot but Merge-Books . Well, the old behavior should count as a bug, right?'... . For historical accuracy I should point out that this...

Re: It walks like a clone, it quacks like a clone ...

I think you missed his point. Top engine devs are not lurking around in the talkchess subforums anymore. They are in discord servers. Whether that be Stockfish, Leela, or smaller ones like their own Koivisto one or OpenBench's discord. I think that's a pity. Discord is a chat program and the signal...

Re: Anti-Engine Puzzle

Of course DTM from starting position still is 46 Yet now made a complete .pgn with comparison of the author's solution and freezer's database of the starting position from first to 35th move. At any alternative move with different DTM commented: [Event "?"] [Site "?"] [Date "2021.03.08"] [Round "?"...

Re: Anti-Engine Puzzle

Interesting!! I find it amazing that the optimal solution is 46 moves, which is exactly the same as the "official solution", but the official solution is very different. Would it be possible to check with Freezer that the official solution is correct? Well, I'd say, that's what I already did here, ...

Re: Anti-Engine Puzzle

There is no PST in an EGT generator. And no white King either, the way I used it. I am sorry. What I meant was that changing the PST for the white king should help solving the puzzle but it won’t fix it. Not generating moves for white king on e2 (and removing the moves from and to where the black p...

Re: Anti-Engine Puzzle

It seems this can be easily solved by constructing a TB. Only about 10 million positions to consider (assuming that after the white king moves to f1 the configuration of 7 pieces in the lower right corner is never touched).

Re: Are neural nets (the weights file) copyrightable?

My idea is that "the right to distribute something" is not something that is acquired once and then kept forever. You can lose the right to distribute something. If you accept that FF2 is a covered work then the distribution of it is a violation of the GPL-3 license attached to SF. Hence you can no...
