Messages to Students:

Instructors:

Prof. Amos Fiat (fiat@cs.tau.ac.il)
Prof. Hanoch Levy (hanoch@cs.tau.ac.il)

This page will be modified during the course, and will outline the classes

Text books:

Intoduction to Algorithms, by Cormen, Leiserson and Rivest.
Data Structures and Algorithms, by Aho, Hopcroft and Ullman.
The course follows both books. Recommended purchase - first book (to be used by other courses).

Course syllabus:

The course will deal with data strucutres and their use in the design of efficient algorithms.
Subjects: Growth of functions and asymptotic notation; amortized analysis; recurrences: the substitution, master, and iteration methods; elementary strucutres: lists, stacks, queues; trees: ordered trees, binary trees, labeled trees and expression trees; set representation and manipulation; dictionary and hash tables.

Tentative course outline. The actual order of the classes differs from this outline. The actual material may vary as well.
