11.1.6 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.

A random position from the database is found in Random position from hypergammon database. The equities and percentages in your own database should be very similar (if not identical):
