Hi Ned!
I'll paste in some lines from documentation:
Two-sided databases for Hypergammon
As the generation of the Hypergammon databases are an iterative
process it's not possible to give MD5 checksum for these, as it depend
heavily on your convergence threshold, the number of restarts, and
rounding errors.
Below is a random position from the database. The equities and
percentages in your own database should be very similiar (if not
identical):
GNU Backgammon Position ID: ADAAAQAkIAAAAA
Match ID : cAkAAAAAAAAA
