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 sim-
       plified 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.
