Daniel Elliott Loeb send me the following information on Barney Pells METAGAME Game-playing Workbench. The author of the file below is Barney Pell.

METAGAME Game-Playing Workbench 2.0.0

I am announcing the availability of the latest version of the METAGAME workbench. This is a workbench for developing and playing metagame programs. The workbench also allows users to enter and modify the rules of chess-variants, and test them out against other humans or programs. This release contains the following: This is an EXPERIMENTAL system. You may take it and use it at your own risk. No warranties are given or implied. The primary concern has been to develop a system which could play all the games in this class, using a declarative respresentation suitable for machine learning and meta-reasoning.

I would appreciate any feedback (at (email removed contact us for address) concerning the system and its use. I will try to be responsive to any comments/requests/bugs/etc.

To receive and build the Metagame Workbench:

The metagame system is implemented in SICStus Prolog, version 2.1,
which is available by email to:  (email removed contact us for address)
This new release also supports Quintus Prolog. 
HOW TO ftp:

 1) Issue FTP command to connect to our ftp server

 ftp or ftp

 When asked for Name, respond with "anonymous"
 When asked for Password, respond with your email address

 2) Issue change directory command to where the METAGAME system is
 cd users/bdp
 3) Change transfer mode to binary
 4) Now retrieve the METAGAME system
 get metagame2.0.tar.Z
 5) Exit the ftp program
 6) Now uncompress and untar the files
 uncompress -c metagame2.0.tar.Z | tar xvf -

 Note that this command creates a subdirectory Metagame in the current
 directory and uncompresses the files into that directory.
 7) (Optional) Remove the compressed METAGAME system

 rm metagame2.0.tar.Z

 8) Change into the Metagame directory

 cd Metagame

 9) Build the system

 make install

 10) Run the system


  That will put you in the system proper.  After that, use the help
  menus to find out what to do.

  Remember that if you ever encounter an error which fails to prolog,
  just type: "metagame."  to get back into the system.

 11) Have fun with the METAGAME system...

Note that some of these instructions (1-7) apply only to Berkeley derived 
Unix, eg BSD, SunOS, etc.

Also available are two papers on Metagame:
        Metagame: A New Challenge for Games and Learning
        Metagame in Symmetric Chess-Like Games

And one paper on Go:
        Exploratory Learning in the Game of GO

To retrieve and print these papers:

1) Get them from FTP, as described above

2) uncompress them:


3) print them to a postscript printer:
