Homework Policy:
It is required that the homework submitted by each student be his/her own thoughts. Discussion with others about how to do the assignment is acceptable, indeed encouraged. However, the final writing up of the assignment should represent each student's understanding of the problem and should not be copied from another student.

You are strongly encouraged not to rely on solutions that can be found on the web, at least until you have thoroughly exhausted your own efforts, and those of your colleagues. And then you must reformulate the solution in your own words and ideas.
