**Class time and location**. Mondays and Wednesdays
3:30-4:45PM, at CIWW 201.

First meeting: Monday, January 2

**Exam Dates. **Midterm: Wednesday, March 21, in class; Final:
TBA.

**Office hours**. Monday 5-6pm, and by
appointment.

**Mailing list, home page** TBA.

**Course Goal and Syllabus**. The goal of this class is to
develop your ability to evaluate and write mathematical claims in
computer science, so as to be able to:

Broadly speaking, this course will be studying what can and cannot be computed, and when something can be computed how simply it can be done. The specific topics covered will include proofs techniques, finite automata and regular languages, pushdown automata and context free languages, decidable and undecidable problems, and NP-completeness.Judge when a problem is solved (and equally important, when it is not yet solved). Explain such mathematical claims clearly and precisely.

**Attendance.** You are strongly encouraged to
attend all the classes of the course. The course material would
be quite challending for one to study on their own relying just
on the notes. The interaction and group energy allowed by class
attendance is extremely helpful for most people.

**Assignments**. There will be more or less weekly homeworks.
Late homeworks will not be accepted (except in the event of
illness or other unavoidable circumstances). If for some reason
you will be unable to hand in a homework on time, please discuss
it with me beforehand. While you may discuss homework
problems with your fellow students, you must write up your
solutions in your own words. Be aware that you are unlikely
to perform well on exams unless you gain practice at problem
solving on the homeworks.

To facilitate the management of the homework, I ask that you do
the following.

1. Write the solutions leaving space for grading comments (e.g. margins on both sides, and top and
bottom, and don't use tightly spaced lines).

2. Hand in you solution on Monday at the start of class.

3. You may handwrite your homework, legibly of course, or typeset
it. The best way to typeset mathematical material is to use Latex.

**Academic Integrity**. Please take note of the
course and departmental policy on this matter: http://www.cs.nyu.edu/web/Academic/Undergrad/academic_integrity.html

**Assessment**. Homeworks will comprise 40% of the overall
grade, the midterm 20% and the final 40%. However, if the
grade on the final is better than the midterm grade it will
replace the midterm grade. Exams will be closed book.

**Required text**. The required text is the book Richard
Cole has been
writing and teaching this course from for several years. If you want a published
textbook, you might consider: Michael Sipser, Introduction to the
Theory of Computation*,* Thomson. The most recent
edition has the advantage of including solutions to a selection of
problems. However, let me point out that the approach we will be
taking diverges quite a bit from this text. Another possible text
is: Daniel I.A. Cohen, Introduction to Computer Theory. This
text provides a lot of examples and can be quite helpful. However,
it does not cover material for the whole course, and the approach
it takes differs even more from the one I will be using in this
course.

**Homework Details**. You may handwrite your homework, legibly
of course, if you prefer, rather than typeset it. In my
experience, when typesetting, often too much effort is spent on
the appearance of the homework and minor yet significant errors
are overlooked. Also, if your homework solution has multiple
pages, please staple them; please don't fold down the corners or
use paperclips, for the pages are much more likely to come apart.
Finally, if handwriting, please use an easy to read ink color
(blue or black, not red or green).

**Past Courses**

This course will be quite similar to the one I gave last year.
This course is very strongly based on the course with the same name
given by Richard Cole the year before. You can look at the homepage of that
course here (but note that I deviate from Richard's course in some places). I wil try to mention the points
where our course deviates from Richards notes.
