Prerequisite(s): COS 226 or with permission of the instructor.

COS333 - Advanced Programming Techniques (Fall, Spring)

This is a course about the practice of programming. Programming is more than just writing code. Programmers must also assess tradeoffs, choose among design alternatives, debug and test, improve performance, and maintain software written by themselves & others. At the same time, they must be concerned with compatibility, robustness, and reliability, while meeting specifications. Students will have the opportunity to develop these skills by working on their own code and in group projects.

Classes: Two 90-minute lectures.
Prerequisite(s): 217 and 226 (as corequisite).

COS340 - Reasoning About Computation (Fall, Spring)

An introduction to mathematical topics relevant to computer science. Combinatorics, probability and graph theory will be covered in the context of computer science applications. The course will present a computer science approach to thinking and modeling. Students will be introduced to fundamental concepts such as NP-completeness and cryptography that arise from the world view of efficient computation.

Classes: Two 90-minute lectures and one 50 minute precept
Prerequisite(s): COS 126 and 226 (or sufficient mathematical background), and MAT 175, 202, 204. COS 226 can be taken along with COS 340 in the same term. Please contact the professor directly with any questions you may have..
