Additional Help

    For a tutoring session with one of our TAs, you can contact Tim (tsm78@cornell*) or Mihailo (mrr86@cornell*) to arrange a session. The session will focus on the course material and HWs.

Regrade Policy

    Regrade requests will be considered if:
    - they are handed to Prof. Hopcroft or TAs within one week of the time that the given homework or exam is returned to the class.
    - the answer was falsely graded as incorrect. So, in particular, we will not accept requests for higher partial credit.
    - they come with a written explanation, stapled onto the assignment, of why the given answer was right.

Exams: 

    The midterms will be in-class (at the class time and location).
  • First midterm: Friday, 2/27
    •
  • Second midterm: Wednesday, 3/25
  • Final: 9am - 11：30am Satuarday, 5/16, G01 Gates Hall

Homework:  Questions for the HWs are from Kannan/Hopcroft textbook (see above). Students are encouraged to work together but each must submit his own HW (written in his own words). The only requirement is that you understand everything you turn in. You must show all your work to receive substantial credit. These include all the relevant part of your code for the coding questions and the assumptions you made/parameters you used that were not specified in the question text.   You are expected to type your solutions (i.e. no handwriting) and electronically submit to CMS.
