The most important prerequisite for this course is CMSC 203 Discrete Structures. You will be expected to read, write and understand mathematical proofs. Although CMSC 202 Computer Science II is formally a prerequisite for this course, this prerequisite is mostly for programming maturity rather than technical content. In particular, no programming projects will be assigned.

There are two objectives for this course: 1) to introduce the student to the concepts in automata theory and formal languages, which form the foundations of theoretical computer science; and 2) to continue the development of the student's skills in reading, writing and understanding mathematical proofs.

Final grades will be based upon homework assignments (36% total), quizzes (40% total) and the final exam (24%). The syllabus lists 13 homework assignments and 5 quizzes. However, if a homework assignment or quiz is canceled and not made up (e.g., because school is closed for snow or hurricane), the proportion of your grade from homework, quizzes and the final exam will remain the same. That is, homework will still count for 36% of your grade and quizzes 40% of your grade (each homework or quiz will have greater weight). In any case, the lowest homework grade from the first 10 homework assignments will be dropped — i.e. you may not drop the grades from Homework 11, 12 or 13.

The final letter grades are based on the standard formula:

0 ≤ F < 60, 60 ≤ D < 70, 70 ≤ C < 80, 80 ≤ B < 90, 90 ≤ A ≤ 100

Depending upon the final distribution of grades in the class, there may be a curve in your favor, but under no circumstances will grades be curved downward.

Grades are given for work done *during* the semester; incomplete
grades will only be given for medical illness or other such dire
circumstances.

In-class quizzes are scheduled for Thursday 9/25, 10/9, 10/23, 11/6 and 11/20. Please make every effort to attend — unexcused absences will result in a grade of zero for that quiz. Each quiz will be held during the last 30 minutes of the class period. The quiz will consist of one or two questions (possibly with multiple parts) on a pre-announced topic.

Since quizzes account for 40% of your final grade, it is the main evaluative instrument for this class. You should think of the homework as practice for the quizzes and the final exam as a second chance to show you have learned the material.

You are expected to attend all lectures. You are responsible for all material covered in the lecture as well as those in the assigned reading. However, this subject cannot be learned simply by listening to the lectures and reading the book. In order to master the material, you need to spend time outside the classroom, to think, to work out the homework and understand the solutions.

Assignments are due at the beginning of lecture. *Late homework
will not be accepted — this is to allow for timely grading
and discussion of the homework solutions.* Reasonable provisions
will be made for students who are delayed by traffic, who are on
travel, ... *Late homework will be rejected from students who
have obviously been working on homework instead of attending
lecture.*

Partial credit will be given for serious attempts on the homework problems. So you should simply turn in whatever you have accomplished by the beginning of class. If you cannot attend lecture when homework is due, for some honorable reason, you must make arrangements to submit your homework directly to the instructor. Do not ask another student to submit your homework for you. This is to reduce the temptation to cheat (see below).

You are permitted, *but not encouraged*, to work with other
students on the homework problems. Most of the homework assignments
are straightforward and should be done independently. This increases
the likelihood that you will have mastered the material for the
quizzes. The occasional brain teaser is more suitable for collaboration.
If you do collaborate with other students, you must acknowledge
your collaborators by listing them on the last page of your homework.
Also, you must write up your homework *independently*. This
means you should only have the textbook and your own notes in front
of you when you write up your homework — not your friend's
notes, your friend's homework or other reference material.

You should not have a copy of someone else's homework under any
circumstance. For example, you should not let someone turn in your
homework. Cases of academic dishonesty will be dealt with severely.
At the very least, *students who submit copied homework
assignments will receive a grade of 0 for that assignment —
this applies both to the person who copied the homework and to the
person who allowed the his/her homework to be copied.*

The final exam will be given on Thursday, December 11, 10:30am – 12:30pm in Fine Arts 015.
