Thad: I am not sure what exactly you wish to analyze, but GNU Backgammon has some roll out capabilities. Plus, it can be run in "Tutor" mode as far as I remember.

AlliumCepa: I *think* that they're trying to find some means of analyzing the rolls themselves--in isolation--apart from the way they might be used in backgammon.  I suspect there are (or were, a while ago) some fairly regular departures from randomness in the routine(s) that govern the rolls here.  But analyzing and demonstrating that would have been difficult.
