I think what you have is a "constraint satisfaction problem". There are packages in Python that address it, but I have no experience with them and therefore cannot make any recommendations. This one http://pypi.python.org/pypi/constraint/ ...has an example similar to your problem which may help you get started: http://www.logilab.org/3441 > I'm using python 3 on windows. I see no mention of Python 3 on their site, so you probably have to resort to Python 2 should you end up with the solver mentioned above. > Below is how far I've gotten. I'd forget the database for the moment, but keep the code to verify the solution once you have arrived at it through other means. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
