Choosing a Coherent Set of Electives

The grade point average is but one way to measure the quality of an undergraduate record. An equally important attribute concerns depth-of-education, something that is best measured by the choice of elective courses. While required core CS courses ensure breadth-of-education and set the stage for more specialized work, it is through the choice of electives that you can communicate an appealing level of curiosity and a readiness for the future.

With this in mind, the faculty have developed a collection of vectors that promote coherent, in-depth study.  Each vector has a magnitude (typically four to five courses, which may be internal or external to CS) and a direction representing a particular "line of inquiry" within CS.

The faculty expect the set of vectors to evolve over time and plan to introduce or modify vectors as they see new directions for the department and the field.

Pursuing a vector (or one of its more specialized tracks) is optional and not a requirement for graduation. It should be driven by academic interest alone rather than based on risky predictions of where the field is going. The best way to ensure a successful career after you graduate as a CS major is to practice now the art of being intellectually nimble. Tumultuous times call for mobility. Cultivate a broad knowledge of the field and show the world through your transcript that it empowers you to go deep and to learn new areas. Choose your electives as if your life depended on it. It does.

Vector Descriptions 

NOTE: The "F" notation Fxxx (or variants like F7xx) is used, informally speaking, to denote an Four or Five or, um, Six-thousand level Full-Fledged elective. It does not mean a 4000-level course (otherwise, we would have written "4" instead of "F".) Specifically and technically, it stands for any course that's at the 4000-6000 level, at least 3 credits, not an independent study or teaching for credit, and not required by the CS major. For example, Fxxx includes 4700, 5620, and 6110, but not 4820 (required by the major), 4090 (teaching experience in CS), 4999 (independent study), or 4121 (fewer than 3 credits). As another example, CS F4xx includes CS 4450 and 5430, but not CS 4410 (required by the major), 4411 (too few credits) or 4700 (doesn't match the pattern!).

Since 4110 and 4120 are typically offered in alternate years, completion of this vector usually requires taking one of these courses by fall of one's junior year.

Vector name: SOFTWARE ENGINEERING

Provides students with the fundamentals of software engineering and extensive implementation experience in a variety of application areas.

Explanation of requirements: a masters-level course on software engineering, two programming-intensive practica in different areas, and an additional course with a heavy implementation component. Experience in C++ is strongly recommended (note that many CS majors are exposed to Linux through the core course CS 3410). 

Required courses: Four total (2 full and 2 half, but at least one additional full course corresponding to one of the half-course practica is strongly recommended (and in some cases required))

  1. CS 5150 (Software Engineering) or CS 5152 (Open_source Software Engineering)

    Note: It is strongly recommended (and in some cases required) that one also take the corresponding "full" course; for example, if one takes 4621 (the graphics practicum), it is recommended that one also take 4620 (introduction to computer graphics)
  3. One of CS 3152(Introduction to Computer Game Development), CS 4152 (Advanced Topics in Computer Game Architecture), CS 4154 (Analytics-Driven Game Design), CS F45x (computer networks), CS 5300 (Architecture of Large-scale Information Systems), CS 5412 (Cloud Computing), 5414 (Distributed Computing Systems), or the following implementation-heavy computer graphics courses: CS 5625, 6620, 6630, 6650.

Vector name: SYSTEMS / DATABASES 

Focuses on design and implementation of the fundamental software systems that comprise our computing infrastructure.

Explanation of requirements: the core operating-systems practicum, and three systems electives (areas include networking, architecture, and so on). The launch-point for this vector is CS4410 (operating systems, a core CS course) and its practicum, CS 4411. Many students follow on with CS4450/5450 (networks, not offered every year), CS 5430 (security) and/or CS 5412/14 (intermediate computer systems: cloud and distributed computing and high performance systems and networking), and other 54xx courses). Note: undergraduates should not have difficulty taking these CS 54xx courses provided that they had no difficulty in CS4410/CS4411.

Required courses: Four total (3 full, 1 half)

  1. CS 4411 (Practicum in Operating Systems) or CS 4321 (Practicum in Database Systems)
  2. 3 additional courses chosen from the following list: CS F4xx, CS F12x (compilers courses), CS F32x (database courses), CS 5300 (the architecture of large-scale information systems), and ECE 4450 (computer networks and telecommunications)

Although any group of courses from the acceptable list will do, many systems students find it especially useful to get a solid background in databases.

Given the definition of "Fxxx" from above, CS F4xx includes CS 4450/5450, CS 5430, CS 5412, CS 5413, and CS 5414, but does not include CS4410 or CS 4411; similarly, CS 4321 is not included under F32x, and CS 4121 is not included under CS F12x.

Track: Operating Systems 

Provides detailed and hands-on knowledge of operating systems and low-level systems software.

In order to build a detailed understanding of operating systems and low-level systems software, the following course is required in addition to the vector requirements:

  • students take one additional course CS 4830 (Introduction to Cryptography) [preferred] or CS4860 (Applied Logic) or MATH 3360 (Applicable Algebra)

Also recommended are INFO 5150 (Culture, Law and Politics of the Internet) or other relevant law or policy courses. Note: undergraduates should not have difficulty taking the CS 54xx courses provided that they had no difficulty in CS 4410/CS 4411.

Focuses on the foundations of managing, processing, and analyzing large datasets

Combines one course plus practicum on data management and courses on large data-driven systems, with machine learning/data mining or information retrieval. In addition to the vector requirements:

  • students take one additional course from CS F78x (Machine Learning) or ORIE 4740 or CS 4300 (Language and Technology) or CS 4740 (Natural Language Processing)

Vector name: THEORY

Focuses on the study of efficient computation, models of computational processes, and their limits.

Explanation of requirements: a course in computability/complexity, two theory electives and an upper-level technical mathematics course

(Recall that CS 4820 does not satisfy this requirement, since the "F" notation indicates a 4000-6000 non-CS-major-required 3+ credit course.)
  3. An additional 3+ credit course numbered MATH THxx, where the thousands digit T is between 3 and 6 inclusive and where the hundredths digit is between 1 and 9 inclusive, or MATH 4010 (Honors seminar: Topics in Modern Mathematics) or CS 4860 (Applied Logic).
