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 analyse 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 con‐ vergence threshold can be changed with the -t option.

OPTIONS

-f filename, --outfile filename Write the hypergammon database to filename. Default is "hyper<number of che‐ quers>.bd", the name expected by GNU Backgammon when using the database. -r filename, --restart filename Restart calculation of the database from the given file, which should be a check‐ point 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.
