This course introduces basic tools and techniques for the design and analysis of computer algorithms. Topics include asymptotic notations and analysis, greedy algorithms, divide and conquer, dynamic programming, network flows, NP-completeness, approximation algorithms, and randomized algorithms. For each topic, beside in-depth coverage, one or more representative problems and their algorithms shall be discussed.

In addition to the design and analysis of algorithms, students are expected to gain substantial discrete mathematics problem solving skills essential for computer engineers.

• Have fun learning!
• Grasp the essential ideas of algorithm analysis and design
  • asymptotic notations analysis
  • typical algorithm design methods: divide and conquer, greedy, dynamic programming, network flows
  • basic graph algorithms: BFS, DFS, MST, ...
  • the notions of NP-completeness, approximation algorithms, and randomized algorithms
• Gain substantial problem solving skills in designing algorithms and discrete mathematics

Prerequisites:

Data Structures (CSE250), Calculus II, and a course that requires formal proofs.
The desire and ability to learn new ideas quickly.

At the end of this course, each student should be able to:

• Have a good overall picture of algorithm analysis and design techniques
• Solve simple to moderately difficult algorithmic problems arising from practical programming situations
• Understand the notions of NP-completeness and approximation algorithms
• Be able to demonstrate simple NP-complete problems
• Love designing and analyzing algorithms

Class homepage:

Work load:

• Heavy! So, start early!!
• Approx. 30 pages of fairly dense reading per week
• 5 written homework assignments (to be done individually)
• 1 midterm exam
• 1 final exam

Grading policy:

• 5 written assignments: 8% each (I reserve my right to add or reduce the number of assignments)
• Midterm: 25%
• Final: 35%
• Assignments due at the end of the lecture on the due date
  • 1 day (up to 24 hours) late: 20% reduction
  • Each extra (24 hours) day late: 40% reduction (which means you don't have to bother submit your assignment if it's more than 2 days late)
• Incomplete/make-up exams: NOT GIVEN, except in provably extraordinary cases

Academic Honesty:

• No tolerance on plagiarism:
  • 0 on the particular assignment/exam for first attempt
  • Fail the course on the second
  • Consult the University Code of Conduct for details on consequences of academic misconduct
  • See also Prof. Shapiro's page on Academic Integrity of the CSE department: http://www.cse.buffalo.edu/~shapiro/Courses/integrity.html
• Group study/discussion is encouraged, but the submission must be your own work
• I will take cheating VERY VERY seriously. Don't waste your time begging !!

Misc. Items:

• Students are encouraged to discuss homework problems with classmates, but the version submitted must be written on your own, in your own words.
• Absolutely no lame excuses please, such as "I have to go home early, allow me to take the test on Dec 1", or "I had a fight with my girlfriend, which effects my performance", blah blah blah. Even when they are true, they are still lame.
• No extra work in the next semester given to improve your grade.
