Rebel 14 GPL project missing file

Missing file in Rebel-14 project, collected from here: http://rebel13.nl/windows/rebel-14.html

From nnue.cpp, we have a reference to a text file that is not included in the project:

#include "g:/epoch-78x.txt"

I do see this text file in the project:

Directory of C:\Users\dannc\chess\Rebel-14-Master\embedded-nnues

I tried using the text file in the embedded-nnues folder:
//#include "g:/epoch-78x.txt"
#include "C:/Users/dannc/chess/Rebel-14-Master/embedded-nnues/rebel-14.txt.txt"

but I got this:

I added these macros:

Code:

#define read_u32_le(buf) \
    (((buf)[3]<<24)|((buf)[2]<<16)|((buf)[1]<<8)|((buf)[0]&0xff))

#define read_u16_le(buf) \
    (((buf)[1]<<8)|((buf)[0]&0xff))

#define read_u32_be(buf) \
    (((buf)[0]<<24)|((buf)[1]<<16)|((buf)[2]<<8)|((buf)[3]&0xff))

#define read_u16_be(buf) \
    (((buf)[0]<<8)|((buf)[1]&0xff))

and then I added a function to find a file's size from the file's name.
Now I can build and run

It has a visual studio project for VS 19 included, also the 64 bit avx2 binary that I created.

I should have made a relative path to the nnue weights file, so you will have to edit the path as appropriate for your system if you want to buld it.

I got an error trying to use this primitive makefile:

Dann, I am new to Visual Studio, I will try to add a project file to the download.

Project file included. Default is AVX2. To change check simd.cpp

You could give them a popcount switch too, I guess.
Plenty of code substitutions possible. Only thing to worry about is if we two end up with different code that then has to be melded.

Scrap that. The popcount64() in the code is never actually called, and the two things that do call it are never called either. It’s there just as part of my useful.cpp and useful.h useful(!) functions. You could just comment the lines away. Better though, would be to have compile switch give an alternative to popcount(), then, if needed in future …..

Hallo,

Rebel 14 vond een mat in 11 snel. Rebel 14.1 had dit na 20 zetten nog steeds niet gevonden. Ik vond dat opvallend... Gr, Kris

Hallo Krisnatoon. Om welke stelling gaat het? Heb je misschien een FEN string van de stelling? Desnoods een screenshot? Je had dit wel in een eigen topic kunnen plaatsen.

De stelling was:

Wit: Kc2, Tb3, pion a4 en g2
Zwart: Kc5, Lb2, pion c3

Groet, Kris

Dankjewel voor de informatie!

Groet, Eelco
