On April 16, Michael Rouse asked a question about classroom creation.
I replied (in part) as follows:

At this point I'd just like to add that, if considering all possible
outcomes is too computationally expensive (which seems likely when one is
working on the scale of Ted's 100-student/4-class example), one should be
able to get results of comparable quality by considering a large number of
randomly generated outcomes.
Additionally, one could employ various non-random and/or semi-random
methods of constructing outcomes, while still using the proposal above to
evaluate them.
my best,
James
