Funny, I was just randomly browsing the RuyDos repository, when I saw a new commit come up, the first one since March. The comment for the commit is: evaluate.cpp from J.M., unchecked; I might regret this ;) This is not an official version, just a development version 1.1.8. https://bitbucket.org/al...

RuyDos is connected to the server, but I won't be around when the tournament starts (sorry!). Could you please add it?

Thanks,
Álvaro.

I agree with most that you wrote. But Java really is super-simple compared to C++, I'd even say it's trivial. C++ is easily the most complex language out there (and I don't think it's a good thing, sane people don't like complexity). I also don't think that the comparison of C and high level assemb...

Am I the only one that happily uses std::cout without any problems? You can look at uci.cpp in RuyDos.

In Shokidoki I consider a move easy if there is at least a 300cP gap between its score and that of the second-best move, in all iterations. How do you get the score for second best in ID? Do you always perform multi variant analysis? I think the second best (and all others) will just fail low after...

Can you tell me the purpose producing 3 miilion games from only 5953 unique opening lines of which 21% are exact doubles? Yeah, I was hoping Stockfish's behavior would be more random than that. :( If I do something like this again, I'll probably use UCT to grow an opening-book tree with much more v...

If you do use games where White and Black are different engines (TCEC or CCRL), it would be interesting to inform the network of the Elo difference between the players (assuming Elo estimates are available). That input can then be used to implement something like contempt factor in a more principled...

Hi, I had my 8-core Ryzen 7 computer spend about 2 months generating quick Stockfish-vs-Stockfish games. The result is 3 million games that I think could be used for training neural networks, or to tune evaluation functions. I have the games available in PGN format with comments that include the sc...

People say C is even faster than C++, that's why I personally write in C. People say a lot of things, but C is not faster than C++. Anything you can write in C you can write in C++, and the performance will be the same. C++ has additional features and some of those might be slow, especially if misu...

Try using quotes to make the whole FEN string into a single argument:

pg_key "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"
