This course is an introductory graduate course and advanced undergraduate course on the design and analysis of algorithms. We will cover algorithm design techniques such as divide-and-conquer, dynamic programming, and greedy algorithms for a variety of tasks such as sorting, searching, and graph problems. We will also cover lower bounds and computational models.
This course requires undergraduate background in algorithms and/or data structures and, above all, mathematical sophistication. If you feel that you may not have sufficient background, please talk with the instructor John Reif. A good option that has worked well for such students in the past is to take CPS 130 instead, also offered Fall semester. (Master's students can count two 100-level courses toward their Master's degree with approval from the DGS.)
Mondays and Wednesdays (and sometimes Fridays)

Consult the schedule of lecture topics for a list of topics and a copy of lecture notes for the lectures to date. Other handouts can be found in the handouts directory, and homeworks and old midterm and final exams can be found in the homework directory.
Theoretical Computer Science Cheat Sheet: ps pdf Ten pages of commonly used formulas and other useful information for computer scientists. By Professor Steven Seiden of Louisiana State U.
Mary Vernon's Useful Formulas Page ps pdf
How to Solve and Write Up Homework Problems: ps pdf Helpful advice from Prof. Alan Sherman of the U. of Maryland, Baltimore County.
Efficient Reading of Papers in Science and Technology: ps pdf This short brochure from an unknown author is well worth studying.
Free Online Dictionary of Computing: An online glossary, with cross-referencing.
Dictionary of Algorithms, Data Structures, and Problems: Includes definitions, problem analysis, code samples, and in some cases animations.
Homeworks are due roughly every week and must be turned in before class on Wednesday of the week they're due. No credit is given for late solutions. For exceptional circumstances, see John Reif in advance.
Homework assignments will be archived in the homework directory. The postscript version, pdf version, and source LaTeX code will be available for each homework problem. LaTeX should be used for typesetting homework problems.
Details about proper style for writing up homework solutions and some guidelines for grading appear in ps or pdf format. More detailed notes on how to write (much of which is beyond the scope of this course) are available in gzipped ps or pdf. Plus you can make use of the LaTeX source file, the LaTeX macros, a LaTeX template file, a LaTeX guide, and hypertext LaTeX help.
For homework problems, discussion among students is permitted, but students MUST write up solutions independently on their own. No materials or sources from prior years' classes or from the Internet can be consulted. Breaking the rules can result in expulsion. Each student is required to make a copy of this page, sign it indicating that the contents are understood, and turn it in to John Reif.
Student grades for the class will be based on
· Homework assignments (approx. 30%).
· Closed-book midterm exam(s) and final exam (approx. 55%).
· Class Project (approx. 15%).
