How about docs on gnubg's net engine? (it cheats!) {wa: Re: [ Bug-gnubg] Searching for "BKG—A Program that Plays Backgammon"

[Roy A. Crabtree]

You must be an antiquarian like me, to recall such ancient information processing techniques ...

    (tongue/glib)

As a side kvetch: Iws looking on gnubg's site for refs to the internal NNP engine, did not see them.

Is this only in the code, or is there a white paper somewere I was too blind to see?

By the way, the engine (more correctly, the learn-ed net) us much more clever than you may think:

It has succesfully "hidden" the several ways it "misleads" players into traps, including "cheating"***:

   It plays the _players_ as much as it plays the _game_.  It uses the players "tells":

       game strategy shifts based on conistently flawed playing.

             Second kvetch: Am I incorrect in assuminhg that the net is not locked during successive plays?
                  That it learns in the current match as well?

                 (There is an outside posibility i Have a viral trap catching the dice throws covertly)

                 (Please note: since the game in fact has an option to throw the best to worst roll for each player,
                   this is a much easier viral hack than you might think).

    If you look carefully, and think a while, then follow the pattern it has, you can esily see it.

             If you understand signal theory (event/condition/timing/cascade), it will pip (sic: pop) out at you.


*** The code is scrupulously clean; nonetheless, 
     when a naive player says it (gnubg) cheats, 
     it (the neural net) does.

Cheers.

Offhand I can think of a number of ways to get it:

You could also contact ICGA, of which Levy is president, and see if it
was printed in some back issue and if so the cost of a reprint/copy.
Or ask ICGA where it could be found outside of the book.

If you know of a magazine where it was printed, you can find one of
several reprint services that are available on the internet, or you
can contact a major library that carries the magazine, such as the NY
Public library, have them copy it, and send it (for a fee). This is a
standard service.

Finally, you could try locating Berliner himself, presuming he isn't dead yet
