Computer Science (2020 - 2022)

Policy on Declaration of Major or Minor

Students must complete either CSCI-UA 101 or 102 (depending on placement) with a grade of C or better before they can declare the major or minor in computer science; the joint majors with economics and mathematics; and the joint minor with mathematics. To declare the joint major in computer and data science, students must first meet this prerequisite and also complete either DS-UA 111 or 112 (depending on placement) with a grade of C or better. To declare the minor in web programming and applications, students must first complete their choice of either (1) CSCI-UA 2 or 3 (depending on placement) or (2) CSCI-UA 4 with a grade of C or better. These policies apply to all NYU students, not just to those matriculated in CAS.

Major in Computer Science

The major requires twelve 4-point courses (48 points). Requirements include the following five courses (20 points) in the Department of Computer Science:

Introduction to Computer Science (CSCI-UA 101)
Data Structures (CSCI-UA 102)
Computer Systems Organization (CSCI-UA 201)
Operating Systems (CSCI-UA 202)
Basic Algorithms (CSCI-UA 310)

The major also requires two courses (8 points) in mathematics:

Discrete Mathematics (MATH-UA 120)
Calculus I (MATH-UA 121) or Mathematics for Economics I (MATH-UA 211)

Students must also take five elective courses (20 points) to complete the major, selected from courses numbered CSCI-UA 4XX (400 level electives).

Students may replace a 400-level elective with one of the following mathematics classes:

Calculus II (MATH-UA 122) or Mathematics for Economics II (MATH-UA 212). Students must choose one calculus track or the other and cannot mix courses from the two tracks.
Linear Algebra (MATH-UA 140)
Probability and Statistics (MATH-UA 235)

A maximum of two MATH-UA classes can be substituted for 400 level electives.

Policies Applying to the Major

A grade of C or better is necessary in all courses used to fulfill major requirements; courses graded Pass/Fail do not count toward the major.
To enroll in Introduction to Computer Science (CSCI-UA 101) students must first fulfill the prerequisite Introduction to Computer Programming (No Prior Experience) (CSCI-UA 2) or Introduction to Computer Programming (Limited Prior Experience) (CSCI-UA 3). Alternatively, they must first present a score of 3 on the AP Computer Science exam; students with a score of 4 or 5 may also register for CSCI-UA 101 (they are encouraged but not obliged to start with CSCI-UA 102), but they will forfeit the AP credit. Finally, students may take a placement test given by the department to enter CSCI-UA 101.
Advanced Placement (AP) credit for Computer Science A is the equivalent of CSCI-UA 101 and counts toward the major. However, the AP exam in Computer Science Principles cannot count toward any major or minor in this department.
Students who score a 4 or 5 on the AP Computer Science exam are encouraged to register for Data Structures (CSCI-UA 102) but are not obliged to; they may choose to take CSCI-UA 101 before CSCI-UA 102 (and forfeit the AP credit).
Students will also lose AP credit if they take certain other courses in the department; this is noted in the relevant course descriptions.
Students are required to take CSCI-UA 101 through CSCI-UA 201 in sequence.
Note that Albert will automatically block: students who complete CSCI-UA 2 with a C or better from registering for CSCI-UA 3; students who complete CSCI-UA 467 with a C or better from registering for CSCI-UA 61; and students who complete CSCI-UA 479 with a C or better from registering for CSCI-UA 60.
CAS students (in any major or minor) are not permitted to take computer science courses in the Tandon School of Engineering.
Those interested in the honors program should start the major early enough to take major electives starting in the first semester of junior year.
Those interested in spending a semester away should work out their schedule with an adviser as early as possible.

Joint Major in Computer and Data Science

The prerequisite for declaring this major is completion of (1) either CSCI-UA 101 or 102 (depending on placement) and also (2) either DS-UA 111 or 112 (depending on placement) with a C or better. The joint major in computer and data science is designed for students who seek comprehensive training in two bodies of knowledge: (1) computer science, an established field that advances computing, programming, and building large-scale and intelligent systems; and (2) data science, an emerging field that leverages computer science, mathematics, and domain-specific knowledge to analyze large data collections using data mining, predictive statistics, visualization, and efficient data management. The joint major in computer and data science trains students to use data science systems, the automated systems that effectively predict outcomes of interest and that extract insights from increasingly large data sets. This training enables students to participate in harnessing the power of data and in influencing policies that will govern the rollout of data science technologies. In addition, students gain the ability to build such systems.

This is an interdisciplinary major (eighteen courses/72 points) offered by the Department of Computer Science and the Center for Data Science. A grade of C or better is necessary in all courses used to fulfill joint major requirements. Interested students should consult with the directors of undergraduate studies in the department and the center for additional information. Please note that the CAS minor requirement associated with the major in data science is waived for the computer and data science joint major, just as it is waived for a data science major pursuing a double major.

Computer Facilities

The Department of Computer Science has access to a variety of computers for both research and instructional use. The primary platforms for instructional use are PC and Mac. Upper-level courses may also use Linux workstations and servers and High-Performance Computing resources. Most instructional facilities are operated by NYU Information Technology Services (ITS), and students should visit the ITS website for complete information on services, hours of operation, and conditions of access.

The Department of Computer Science also has its own network of Windows and Linux workstations, used primarily for research purposes. The department operates research laboratories for experimental computer science research in machine learning, natural language processing, systems and networks, theory and cryptography, formal networks and verification, and computer graphics; most are located at 60 Fifth Avenue. Selected undergraduates assist in work on these areas at this facility.
