NAME¶
bearoffdump - dump a position from the GNU Backgammon bearoff database
SYNOPSIS¶
bearoffdump file id
DESCRIPTION¶
bearoffdump takes the path to a GNU Backgammon bearoff database and a
position number and dumps the bearoff information for that position. It can be
called on either the one-sided bearoff database, normally
/usr/share/gnubg/gnubg_os0.bd; or the two-sided bearoff database,
normally
/usr/share/gnubg/gnubg_ts0.bd. The output from the former
includes the probabilities of bearing off all checkers in varying numbers of
moves. The latter only gives the probability of winning and doubling cube
equity.
The
id is difficult to derive if you don't know GNU Backgammon internals.
Each possible combinatorial position of checkers and points is assigned a
position number,
id divided by that number is the player position, and
id modulo that number is the opponent position. The number of points
and checkers is set when building the bearoff database and are shown by
bearoffdump when run with any
id.
