Recommended Background

Interest in the subject matter and good standing in CS courses should suffice. Exposure to discrete mathematics will also help.

Assignments

There will be assignments (in total of 5 or 6) composed of made-up questions, exercises and review questions.

Examinations

There will be a single in-class examination. You will be allowed to bring a single page, hand written cheat sheet (photocopies and print-outs are not allowed).

Final Presentation

Towards the end of the semester the students will be required to pick a subject area relevant to the lecture material in consultation with the instructor. Each student will give a brief/in-class presentation and a report during the last three weeks of the semester.

Grading

The following weight distribution will be used to calculate the fınal grade:

· 40% Assignments

· 40% Exam

· 20% Presentation
