Policies: |
Integrity policy: The course policy follows the department's default honor policy with the following modifications. Weekly reading summaries and homeworks (problem solutions, programming codes, and written reports) must be done individually. Collaboration on graded assignments is not allowed. If you wish to use code or software tools developed outside of the class by you or by someone else, you must obtain the instructor's permission before using these resources. Violation of these policies will be reported to the Honor Council or to the Graduate School. If you are unsure whether a practice is acceptable, please ask the instructor for clarification by e-mail or during class or office hours. Homework submission and Late homework policy: Homeworks are due on Friday 11:59pm on the submission week. All homeworks should be submitted through Blackboard. A penalty of 50% will be applied for homework submitted within the next 24 hours after the due date; Zero credit will be assigned after that. All homeworks (even with zero credit) must be turned in order to pass the course. Weekly reading summary submission: The weekly one-page reading summaries are due at the beginning of the first class in that week. The weekly reading summary should cover readings assigned for the entire week. Please bring it to the class. Do NOT send them through email. There is no late date for reading summaries. |
