Re: Legal status of Eman?

Well, they can only demand it because you offered to provide it (to another person, but the offer transfers together with the binary). If you have not made such a written offer, but provided the binary to the person (with or without source), no one can have any claim on you when that person releases...

Re: Legal status of Eman?

There is an exception about private software. If you make a modifications for a particular user (or company) and don't release to public, you are free to do that without having to share either binary or sources with the world. I think there never is an obligation to share source with the world. Jus...

Re: Possible "real" hash collision

9 of 9 "real" hash collisions are either a fantasies or bugs why do you think kh2 a blunder? the position is lost anyway If they don't exist, why then verify the tt-move?

Re: Legal status of Eman?

Giving a modified executable to anyone without the source code is a GPL violation. But like with most breaches of the law, if no one presses charges, this has no consequences. Anyone getting the executable this way can demand the source code, (no matter what they made you promise in order to get the...

Re: Moving instantly based on the transposition table.

This is something that is supposed to never happen, right? The depth you need in the root is the largest depth of the entire search, so only positions that have been searched at the root before should satisfy the requirement (but then you are already repeating positions, and mindlessly sticking to t...

Re: Little thought experiment

On another world there exists a very powerful computer using alien tech. This chess machine does a true (as in literal) Brute Force search 15 plies deep. It uses current SF E.F How many plies deep, approximately, would normal SF have to search to equal the strength of the 15 plies alien machine? Wh...

Re: Opposite Color Bishop Endgames

That just means it has a high Elo. Like I pointed out high Elo and 'good at chess' are entirely different things.

Re: Opposite Color Bishop Endgames

There shouldn't even have been a story. LC0 is poor at tactics. So it is a poor chess program. PERIOD. The initial statement was never withspoken.
