Cerebellum book support

[ChessMan3]

Hello! It is not an issue. I think I can speak on behalf of all the fans of Cfish: could you add support for the Cerebellum book as in Brainfish or ASMfish? I think all Cfish users would like this.

I may have a look when I find some time.

[ChessMan3]

Thank you for adding Cerebellum book support! I have some error when compile:

search.c:31:10: fatal error: polybook.h: No such file or directory

include "polybook.h"

[Saugstrahler]

Hi Ronald, I get the same error:

search.c:31:10: fatal error: polybook.h: No such file or directory

include "polybook.h"

      ^~~~~~~~~~~~

compilation terminated.

[syzygy1]

A small oversight :-)

Hi, I tried today with CFish and book Cerebellum_Light_Poly.bin. Compilation works fine, but book does not work, engine makes no move. Same books works for me with asmfish. In comparison to Asmfish, CFish does not have the "Ownbook" UCI option.

[syzygy1]

It works for me:

$ cfish setoption name BookFile value /home/ronald/cerebellum/cerebellum.bin info string Book loaded: /home/ronald/cerebellum/cerebellum.bin go movetime 1000 bestmove e2e4

Thanks to Mr. De Man. I compiled this cfish on androids. The book works (only I had to write in the file ucioption.c the path to the folder where the book lies because of the file system features on the android). Now everything works fine!

[Denzwell]

This version does not work well. The engine stop to move after last book move under windows system.

Which GUI are you using? Does the GUI have a "logging" option you can turn on to help debug? If yes, turn logging on and post the output when it stops playing. It is working fine under macOS using xBoard with no issues at all.

[Denzwell]

I use this engine on playchess . I use my ctg book and cerebellum. With brainfish i can use two books. Cfish can insert debug file for that

[MichaelB7]

Sorry - I will not be able to help. MacOS and xboard here. No windows.

[Denzwell]

On windows setoption name BookFile value E:\books\cl.bin info string Book loaded: E:\books\cl.bin go movetime 1000 <nothing (no moves)>

[MichaelB7]

Just to confirm , you downloaded the cerebellum book that is in polyglot format? - the old format would not work with Cfish. Since it is a polyglot book ,any GUI that accepts polyglot books will also be able to read it. I only ask , because it is unclear in the name of the file that you are trying to load that it is the correct file.

yes i just renamed polyglot cerebellum.bin book to cl.bin. i use the same book with brainfish and it works fine.

[ChessMan3]

Works fine with Cute Chess 0.9.4, under Windows 10 x64

============ UPD: works only on 1 core. When i set 2 cores or more - not working.

[Denzwell]

can you try it with fritz 15 Gui please ?

[Denzwell]

With Shredder Gui without book, engine works fine. And when you set book it does not work

[Denzwell]

i allways use Cfish on playchess, this version with polyglot book does not work. i am sure

[ChessMan3]

Not working in Fritz 15 GUI with book. Without book - works fine.

====== UPD: works in Fritz only on 1 core. When i set 2 cores or more - not working.

[MichaelB7]

You need to get it to work at command line terminal first - can you try another exe and test at command line as you did before ?

[ChessMan3]

Works fine in Aquarium.

[CoffeeOne]

yes, easy to reproduce for me, too: C:\Program Files\cfish>cfish-2017-12-12.exe Cfish 121217 64 POPCNT NUMA by Syzygy based on Stockfish setoption name BookFile value C:\Users\Peter\Documents\Cerebellum_light_polyglot\Cerebellum_Light_Poly.bin info string Book loaded: C:\Users\Peter\Documents\Cerebellum_light_polyglot\Cerebellum_Light_Poly.bin go movetime 1000 info string Transposition table allocated using large pages. bestmove e2e4 setoption name Threads value 8 go movetime 1000 => no answer, also not after 5 minutes

[CoffeeOne]

Maybe I should add, after go movetime 1000, the engine hangs, I cannot even terminate with the uci command quit.

[syzygy1]

OK, I have the same problem when I compile for Windows and run it with Wine. I will investigate.

[syzygy1]

Should be fixed now.

[CoffeeOne]

Works now for me. Thank you very much.

[ChessMan3]

For me too - works fine. (Fritz 15 GUI & Cute Chess)

Thank you!

[syzygy1]

Is the Ownbook option important?

[CoffeeOne]

It is conveniant when you want to quickly switch the Cerebellum book on and off, but for me that is not a common use case, so I am neutral about it :)

[ChessMan3]

For me, this is also not critical.

[MichaelB7]

Not for me - I never touch it. But maybe I should be using it more. I’m a little bit Neanderthal and turn the book off and on by making the path incorrect and correct. Did not realize that was what the option for - I thought it was for something else. Not that I know , I would keep it.

[MichaelB7]

Now that I know...

[Denzwell]

OK it works now. Thanks you very much syzygy. I Will try it this night on playchess

[syzygy1]

You're welcome. Let me know if something seems wrong.

I'll probably add Ownbook one of these days.
