CS 561, Algorithms and Data Structures, Fall 2021


Teaching Assistant

Class Info

The class meets Tuesdays and Thursdays, 3:30-4:45 on Centennial Engineering Center 1041.

Course Description

This class covers advanced topics in Algorithms and Data Structures with a focus on mathematical techniques, proofs and analysis. Topics to be covered will likely include the following: Randomized Algorithms, fingerprinting, data streaming algorithms, coupon collectors, birthday paradox, skip lists; Network Flow: Max Matchings, Min-cut Max-flow duality; Linear Programming, and basic game theory; NP-Hardness and Approximation Algorithms.

Text Book

We will be using the book: Introduction to Algorithms (third edition) by Cormen, Leiserson, Rivest and Stein, in addition to supplemental material and occasional handouts.

Class Discussion via Piazza

I've set up a Piazza forum for all announcements and discussions in this class. Piazza allows for public, private and anonymous questions, and extensive math formatting support. Please use it instead of email, even for direct correspondence with me. I check it once a day around 1pm, and you'll get a faster response than via email.

Note: Some of the material in these notes, including many examples and figures are from Jeff Erickson's class notes for CS373 at the University of Illinois Urbana Champagne.

Previous Classes

Prereq: CS 361 either taken at UNM or equivalent class. You should have taken an algorithms class where you learned proofs of correctness, asymptotic notation, recurrence relations, proof by induction, basic algorithms (e.g. search and sorting) and data structures (e.g. binary trees and graphs). I will assume all students are very familiar with this prerequisite material.

Annihilator Notes

Annihilators are a powerful technique for solving recurrence relations. Following are notes on Annihilators by Jeff Erickson at the University of Illinois Urbana Champagne. Most of my discussion is based on these notes.
