**Qualifying exam**

**Preparatory courses**

There are three introductory undergraduate courses in theory of computing:

- CS 577 covers algorithm design and analysis.
- CS 520 covers automata theory, computability theory, and computational complexity theory.
- CS 435 covers cryptography.

CS 577 and CS 520 form the core that all graduate students in CS are expected to have taken before graduate school; undergraduates who intend to do graduate work in CS should take both.

At the graduate level there are two introductory courses that are offered every year:

- CS 787 covers algorithms.
- CS 710 covers complexity theory.

In addition, there are three more specialized regular courses (CS 809, CS 812, CS 830), as well as the topics course CS 880, which is a full-fledged course but with a topic that depends on the offering. Those courses may not be offered every year. All graduate students interested in theory of computing are encouraged to take CS 880 whenever it is offered.

Although the material for the qualifying exam in theory of computing does not stretch far beyond the material of CS 520 and CS 577, students preparing for the exam should take CS 710 and CS 787 before the exam.

**Reading list**

The purpose of this syllabus is to delineate the material for the qualifying exam in theory of computing. You should feel free to use other sources to learn the material. Most of it is covered in at least one of CS 520, CS 577, CS 710, and CS 787. However, the material for the exam is defined by the list below and not by the latest offerings of the theory courses.

- Algorithms:
- Kleinberg and Tardos,
*Algorithm Design*, Addison Wesley, 2006: entire book. - Motwani and Raghavan,
*Randomized Algorithms*, Cambridge University Press, 1995: Part I.

- Kleinberg and Tardos,
- Complexity:
- Sipser,
*Introduction to the Theory of Computation*, 2nd edition, Course Technology, Cencage Learning, 2006: entire book. - Arora and Barak,
*Computational Complexity: A Modern Approach*, Cambridge University Press, 2009: Part I.

You are also expected to know basic mathematics, as described in the appendix of the text by Arora and Barak.
