  • Algorithm Design by Jon Kleinberg and Eva Tardos, Addison-Wesley, 2006.

    We will cover almost all of chapters 1-8 of the Kleinberg/Tardos text. In addition, I will borrow a small amount of material on divide and conquer algorithms from Introduction to Algorithms: A Creative Approach, by Udi Manber, Addison-Wesley 1989. I will hand out extra material for this.

Another handy reference is Steven Skiena's Stonybrook Algorithm Repository which is also listed in the Useful Links section on the left column of this page.

Mailing List: There is a class mailing list, Follow the link in the left column on this page to sign up. Everyone is expected to be reading cse421 e-mail to keep up-to-date on the course.
