COURSE INFORMATION

Description.   This course surveys the most important algorithms and data structures in use on computers today. Particular emphasis is given to algorithms for sorting, searching, and string processing. Fundamental algorithms in a number of other areas are covered as well, including geometric and graph algorithms. The course will concentrate on developing implementations, understanding their performance characteristics, and estimating their potential effectiveness in applications.

Prerequisites.   COS 126 or COS 217 or permission of instructor.

Lectures.   Attendance is required. You are responsible for all material presented in lecture; some of that material is not covered in the textbook.

Precepts.   We cover details pertinent to programming assignments and exams. You should come to precept prepared to participate in the discussion, not just ask questions.

Staff.   You are welcome to attend the office hours of any staff member.

Online forum.   If you have general questions about the assignments, lectures, textbook, or other course materials, please post via Piazza. Posts marked private are viewable only by the course staff.

Grading.   Your grade for the course will be based on the following components: programming assignments (45%), midterm exam (15%), final exam (30%), exercises (10%), and staff discretion (including participating in precept, answering forum posts, and discovering errata). Occasionally, we make mistakes. To request a regrade, write a brief note indicating the perceived mistake by the grader; attach it to your graded work; and give it to your preceptor within two weeks of when the graded work was returned.

Course website.   The course website

http://www.princeton.edu/~cos226
includes links to course content, including programming assignments, exercises, lecture slides, and old exams. You will also use it to submit programming assignments.

Readings.   The following textbook is required. It contains a wealth of information beyond what we can cover in lecture; it is certain to enhance your understanding of algorithms and data structures.

Programming assignments.   The programming assignments involve applying the material from lecture to solve problems in science, engineering, and commerce.

Exercises.   The exercises consist of short questions on the material in the lectures and readings.

Exams.   The in-class midterm exam is on Tuesday, October 23. The final exam is scheduled by the Registrar.

Course calendar.   You can import this course calendar into your calendar application.

Computers.   You may develop your programs on any machine that you like: we encourage you to use your own equipment. We provide instructions for setting up a Java programming environment under Windows, Mac OS X, and Linux.

Laboratories.   We hire undergraduate lab TAs who are available to answer general computing questions in the Friend 017 lab. They can assist you in debugging, provided you have first made a reasonable effort to identify the bug and isolate the problem. If you have questions regarding the course material or programming assignments, see your preceptor or instructor.
