Andrew McGregor

Associate Professor

Welcome to the Fall 2020 homepage for CMPSCI 611 - Advanced Algorithms.

  • Instructor:
  • TA:
    • Raghav Addanki and Md Abdul Aowal.

  • Textbook: The required textbook will be
    • Lecture Notes from CMPSCI 611 will be available soon via Moodle.
    Other books you might find generally useful (but aren't required) include:
    • Introduction to Algorithms by Cormen, Leiserson, Rivest, and Stein.
    • Algorithm Design by Kleinberg and Tardos.
    • Algorithms by Dasgupta, Papadimitriou, Vazirani.
    You may also find sections of the following books helpful:
    • Randomized Algorithms by Motwani and Raghavan.
    • Probability and Computing by Mitzenmacher and Upfal.
    • Approximation Algorithms by Vazirani.

  • Homeworks and Exams:


  • Honesty and Collaboration Policy: Violating any of the following rules risks an automatic F. Ask if you're unsure about any of the policies.
    • Homework: Collaborating with at most three other students in the homework is allowed and you should mention who you worked with. You're not allowed to use material from the web (or indeed any material except from that listed on the course page) or talk about the homework with anybody outside your collaboration group (aside from the lecturer or TA.)
    • Quizzes: No collaboration! But you can consult any material you like.
    • Exams: Closed book and no collaboration.

  • Schedule and Slides: Here's an approximate schedule for the course. Note that this'll be updated as we go along depending on our progress and, hopefully, we'll get to squeeze in a couple of extra topcs. I'll add slides after each class (some links will be dead until the slides are added).
