MAKEHYPER(6)MAKEHYPER(6)NAMEmakehyper - generate a GNU Backgammon Hypergammon position database
SYNOPSISmakehyper [-nvh] [-f filename] [-r filename] [-c chequers] [-t thresh‐
old]
DESCRIPTION
Hypergammon is a variation of backgammon with a much reduced number of
chequers (usually three). It's possible to fully analyse this simpli‐
fied game and generate a database of position evaluations in order to
play perfectly. makehyper generates such a position evaluation data‐
base.
Since many of the positions are in contact, it's not possible to gener‐
ate 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. Default is
"hyper<number of chequers>.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 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.
