Butterfly

[elorejano]

Hi!
From the webpage i saw that Butterfly use its own opening book but any of the compiles has built it.
Theres no documentation also.
Any help?
Thx

[Charles Browne]

In the source files, in the - openbook.cpp - file it reads:

Code: Select all

  if (!stream)
    {
      printf
   ("\n%s not found. (get it in ftp://ftp.cis.uab.edu/pub/hyatt/pgn/enormous.zip and convert it with pgn2epd.exe < enormous.pgn >enormous.epd. http://remi.coulom.free.fr/)",
    ENORMOUS_TXT_FILE);
      return;
    }


So I suppose you are to download the enormous.zip file from the hyatt site and then use pgn2epd.exe to convert the contents of the enormous.zip file to an epd file called enormous.epd. And you then have the opening book.

Does it work? I do not know. I am curious though so I am still in the process of downloading the enormous.zip file. I might give up though, so you can try it yourself if you want to see if the instructions given are correct.

[Charles Browne]

No luck here.

It may be that it needs to be compiled with the enormous.epd file. Anyway I was unable to get it to work. But I could be mistaken about the necessity of the enormous.epd file in the first place.

If all else fails you could contact the engine's author.

Thanks Guys!
However seems that this engines needs much comands from comandline...
Anybody has the line of winboard.ini for to see the settings?
Regards

[elorejano]

Sorry but when i wrote createbook, Butterfly says "createbook unknown comand"
Of course i builted book.epd and are in the same directory as Butterfly.exe

An executable file for Butterfly 0.0.4 has been posted by the engine's author on the Butterfly website.

command prompt

butterfly createbook < book.epd > book.dat

(What I used anyway)


I do not know if the second move shown below is a book move or not. I made the first move, the engine made the second move. I made a book out of a small PGN file. I have no chess programs installed right now so I have only run Butterfly in the console window.

Code: Select all

Load book ...ok

[elorejano]

Thanks!
Ive managed to create an opening book, but
1)How to set the hashtable?
2)Another settings needed?
3)Are needed something in the command line?
Thanks in advance

Hi Charles,
I download the pgn2epd.exe program and followed the command line at Butterfly console for making a book.epd from a pgn file but nothing happened. Indicate error.
Also i tried bookcreate command at Butterfly console to create a book.dat file but nothing.
Maybe I am doing or understanding something wrong.
Please your comments,

pgn2epd < book.pgn > book.epd


The above worked here for making an .epd file. I downloaded one of Norm Pollock's PGN files of grandmaster games and renamed the file to book.pgn before running the above command.


butterfly createbook < book.epd > book.dat

And the above worked here as far as making a book.dat file and when the engine was ran in the console it listed the book as being loaded, but it didn't look like the book was being used to make moves here. So the commands I used to make the book.dat file could be wrong or something else is amiss somewhere.

I only jumped into this thread to try and give elorejano some help, which I think I failed at. So I think it best if I step aside and let someone else step in to give aid. Sorry I was unable to give a better answer to your question.

Hi Charles,
Sorry but I could not create anything with the mentioned commands. My pgn file was GM2600.pgn renamed book.pgn. I am sure I am making something wrong.
Anyhow the author sent me a computional log that he use to create books. Since I am absolutely ignorant, I do not understand how to emulate that log at my PC.
Maybe it help you and the community.

Butterfly is really, really fussy about the PGN format it accepts.

For instance, if you have a promotion, the only thing accepted will be SAN=P where SAN is the move in modern PGN notation, the '=' MUST be present, and the promotion piece must follow.

Also, ep captures with the notation /ep in the capture are rejected.

I am making a book for butterfly and I will post a link to it when it is done.

[elorejano]

Hi, again!
I could make an opening book for Butterfly but are very large.
Thanks for the help.
But i cant make Butteerfly work under Winboard.
Are needed some parameters from the command line?
If any could, please post your winboard.ini
Thx in advance

[Charles Browne]

I download the pgn2epd.exe program and followed the command line at Butterfly console

Pablo,

Rereading this part of a previous post of yours (quoted above), if I am reading it correctly did you start the Butterfly engine by double-clicking the Butterfly exe file and then type in the information for making an epd file with pgn2epd? If you did do that what you should rather do is in your Windows OS go to "Start > Programs > Accessories" and find and click on the "command prompt" icon which should open a console window. Then change directory - cd - to the directory where the pgn2epd.exe file and pgn file are located and then type the proper command in the console and that should create the epd file. May take awhile to make the epd file depending on how large the pgn file is.


as an example, when I click the command prompt icon on this computer a window opens up showing this

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\soggy_bottom>

I have the pgn2epd.exe and pgn file in a folder named - 00 - in the c:\ drive. So in the console window I change directory - cd - to that folder/directory by typing - cd c:\00 - It looks like this.

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\soggy_bottom>cd c:\00

Then the 'enter' key is pushed and it looks like this.

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\soggy_bottom>cd c:\00

C:\00>

Then the command for making the epd file is typed in (shown below) and the 'enter' key is pushed. And making the epd file should begin.

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\soggy_bottom>cd c:\00

C:\00>pgn2epd < name_of_the_PGN_file.pgn > book.epd

I download the pgn2epd.exe program and followed the command line at Butterfly console

If I misinterpreted what was written above then disregard what I wrote above.

It takes eons of time to build a book (1 MB processed takes 5 minutes).
I had given it a 5 GB input file. That's clearly "right out of the question" as a non-starter.

I will rethink my strategy a bit.

[Dann Corbit]

So far as I can tell, the book code does not seem to work properly.
I created a book, and for which the opening moves from the initial position were:
e4, d4, c4, nf3, g3, b3

(which is based on this statistical report from SCID against a database of high quality games):

The engine promptly moved 1.c3 and then went out of book.
I am giving up for now.

Above is the way I set up my ini file, others do it differently but you can get the gist of it.

Since Butterfly appears to have problems currently with using own book, YOU CAN, if using HG Muller's Winboard, have the engine use a polyglot book through the Winboard GUI instead.

Now I had just been running the Butterfly engine from the console but I went ahead and set it up in Winboard, and as black and as white pieces the engine made moves.

[elorejano]

Thanks!
But how you set the hashtables?
Or are fixed?
