Collaboration policy: While you should first think about the problems on your own, you are encouraged to discuss the problems with your classmates. However, you must write up your own solutions. In particular, nobody should email partial or full solutions to anybody. You must acknowledge any collaboration by writing your collaborators' names on the front page of the assignment. You don't lose points by having collaborators.

Citation policy: Try to solve the problems without reading any published literature or websites, besides the class text and links off of the class web page. If, however, you do use a solution or part of a solution that you found in the literature or on the web, you must cite it. Furthermore, you must write up the solution in your own words. You will get at most half credit for any solution found in the literature or on the web.

Submission policy: Homeworks are due at the beginning of class.

Late policy: Late homeworks will not be accepted.
