Material: COS 521 gives a broad yet deep exposure to algorithmic advances of the past few decades, preparing students to read and understand research papers in algorithms. Course is suitable for graduate students (including those not in CS) and advanced undergrads.
Prerequisites: One undergraduate course in algorithms (e.g., COS 423), or equivalent mathematical maturity. Listeners and auditors are welcome with prior permission.
Coursework: Two lectures per week. 5 homeworks, including some simple programming-based exploration of the lecture ideas (60% of grade). Choice of take-home final in January, or a term project in groups of two (40% of grade). For specific policy on grading, late assignments, etc. please see the grading policy sheet.
Resources: There is no official text -- we will use our own lecture notes and assorted online resources. Please see course webpages from previous years for additional material.

Lectures: Tuesday & Thursday 3:00pm-4:20pm in Friend Center 004.
Office Hours: Pravesh: Immediately after class, 194 Nassau St, Room 219.
Christopher: Immediately after class, Friends 004.
Sixue: Wed. 7:00-8:00pm, 194 Nassau St, Room 307.
Sobhan: Fri. 2:00-3:00pm, 35 Olden St, Room 431.
Piazza: Course discussion and questions will be managed through Piazza. Please sign up here.
Homework: We require students to prepare problem sets in LaTeX.
You can use this template. Submission is managed through Princeton's Blackboard system. A compiled PDF of your
homework should be uploaded by 11:59pm on the due date.
For regular homework problems collaboration is allowed, but solutions must be written-up individually. Students must list collaborators for each problem separately, or write "No Collaborators" if you worked alone. Collaboration is not allowed on bonus problems (see grading policy).
