This reminds somewhat to Temporal_difference_learning.
Although you don't need to dive in that much if your main interest is chess programming. Then start with the Chess Programming Wiki.

Oops, there is still some error. Once again let M=2^16 constexpr Score make_score(int mg, int eg) { return Score((int)((unsigned int)eg << 16) + mg); } This first converts int16 values to their corresponding unsigned values modulo M, these are of course not uint16 values. Let us call that set SU. Th...

I will specify the way it works in a more relaxed, mathematically manner, glossing over implementation issues. If you grok that, you should be able to solve the C++ problems on your own. Let M=2^16, and define, as in C/C++: uint16 := {0,...,M-1} int16 := {-M/2,...,M/2-1} uint32 := {0,...,M^2-1} int3...

This position was specifically posted by me, because the alleged key move 26.h3 is not a "candidate move" for me, by far not. I understand that not everyone bothers that, so i must apologize for having asked for your time. When stockfish presented 23.h3... to me..., i was shocked, so i choose to inv...

Chessbase India has produced an interview, where Kramnik share his thoughts about Nocastling chess and demonstrates a beautiful Alpha Zero self play game.

Depending on what you want, an alias might help, e.g. in your ~/.bashrc : alias cdw='cd ~/my_working_dir' Keep in mind, that bash is always picky about quoting and whitespace. Then do logout/login or type bash if you want to test things and then try cdw on the commandline. Type help alias for short ...

The Advent of Code programming contest is about to start.
I took part last year for the first time, using C++ but dropped out after having solved anything up to problem 9.
Well i think some humilating experience is expected, if you indulge in that matters. Maybe you would do way better?

On recent 16 cores, current SF should find h3 in less than 30 sec.
Why did you post it as a "challenge" ?

I believe you are just a patzer.
If you choose to play the ignorant, this is fine for me.

The alleged solution was indeed 23.h3! and still i believe this is best. 23.Bd3 comes as a surprise but the leela line looks not convincing to me. Only a pawn with some compensation for black, seems to be between somewhat better and clearly better for white. Still i think it is remarkable that in th...
