Homework policy:

Homework assignments will be accepted up to one class period after the assignment is due: later assignments will not be accepted (unless you have obtained permission from the instructor in advance), so that the homeworks can be returned the week after they have been handed in. Collaboration on the homeworks is allowed, although each student must return their own solutions.
