No idea on the literature, but here's my two pence worth:
I'd start by putting everyone in their favourite choice of classes, and seeing how "bad" that is. I assume since you're asking the question that's not a possible solution.
How feasible is it to randomly select students and move them and see how that works? I ask because this is what we'd do before we had computers, but with a computer you could do this a million times a second and try out all the possibilities (it's key to limit the number of moves to narrow the problem space so we don't have to wait for the heat death of the universe first - hence the putting everyone in the "optimal but broken" place to start with.) You'd need a "unhappiness" score for a student which could be computed from the distance they are from their "ideal" courses. You might want to look at adding some sort of power rule to the distance too, since you'd probably be better off with a bunch of slightly unhappy students verses all happy but one very screwed over student. Obviously junk any 'solution' that doesn't meet your class criteria.
Mark.
