This course is required for all students joining the Computer Science M.Sc. program. Students from other departments can request special permission numbers provided they meet the prerequisites as stated below.
The course studies a variety of useful algorithms and analyze their complexity; students will gain insight into principles and data-structures useful in algorithm design.
This course counts as category A for the M.Sc. degree requirement. This course does NOT count as category A for Ph.D. students. Ph.D. students should take 16:198:513 instead.

Textbook: Algorithms by Dasgupta, Papadimitriou, and Vazirani, McGraw Hill
- Expected Work: Weekly Homeworks and a Programming Project (about 25% of the final Grade).
- Exams: Weekly Quizzes plus two Midterms and a cumulative Final
- Learning Goals:
Students will be prepared to contribute to a rapidly changing field by acquiring a thorough grounding in the core principles and foundations of computer science (e.g., algorithmic principles, techniques of program design, creation, testing; and key aspects of computer hardware).
Students will acquire a deeper understanding on selected topics of more specialized interest, and be able to critically review, assess, and communicate current developments in the field.
