NAME

       makehyper - generate a GNU Backgammon Hypergammon position database

SYNOPSIS

       makehyper [-nvh] -f filename [-r filename] [-c chequers] [-t threshold]

DESCRIPTION

       Hypergammon is a variation of backgammon with a much reduced number of chequers (usually
       three).  It's possible to fully analyze this simplified game and generate a database of
       position evaluations in order to play perfectly.  makehyper generates such a position
       evaluation database.

       Since many of the positions are in contact, it's not possible to generate the database in
       one pass; instead, makehyper iterates until the position evaluation converges.  The
       convergence threshold can be changed with the -t option.

OPTIONS

       -f filename, --outfile filename
              Write the hypergammon database to filename.  This option must be given.

       -r filename, --restart filename
              Restart calculation of the database from the given file, which should be a
              checkpoint from an earlier run.

       -c chequers, --chequers chequers
              Set the number of chequers in the game.  The default is 3, for normal 3-chequer
              hypergammon.

       -n, --no-checkpoint
              Do not write a checkpoint file after each iteration.

       -t threshold, --threshold threshold
              Set the convergence threshold.  The default is 1e-5.

       -v, --version
              Show version information and exit.

       -h, --help
              Display usage and exit.
