This course is an introduction to two kinds of formal systems - languages and logics - with important applications to computer science. The study of formal languages underlies important aspects of compilers and other language processing systems, as well as the theory of computation. Various systems of logic and automatic reasoning are put to use in artificial intelligence, database theory and software engineering. The entire course will give you practice in precise thinking and proof methods that play a role in the analysis of algorithms. The programming assignments provide practical experience with some theoretical topics.
Will understand the concepts and relevance of logic, formal languages and automata theory, and computability .
Will be able to able to do mechanical formal proofs, program correctness proofs and solve problems in first-order logic.
Will be able to solve problems in elementary machine models: designing finite-state, pushdown and turing machines.
Will be able to solve problems in formal languages: writing regular expressions, regular grammars, and context-free grammars.
(available as a packet at the bookstore) (soon)
The pace is approximate. Later chapters will not be covered as completely.

Quizzes -- 20%
Programming Assignments -- 20%
Exams -- 60%
The two exams, including the final, each cover about a half of the semester; the final is not cumulative.
Of these exams the highest score will count 35%, and the lowest 25%.
Homework is ungraded.
Quizzes will test homework, typically every other class class.
The lowest quiz grades will be dropped.
There will be small programming assignments in Relational Calculus/ Datalog and AWK.
All testing is closed book.
There is to be NO group work on the programs. Receiving direct contributions to the code that is submitted is considered a violation of the Honor Code. (See cs.gmu.edu/wiki/pmwiki.php/HonorCode for the GMU and Computer Science guidelines.)
It is a departmental requirement that students in CS330 must see their advisor and discuss their degree progress. Students not fulfilling this requirement will receive an Incomplete grade. (Non-majors and graduate students are not included.) The visit must be documented by a signed note or email from your advisor.
Programming assignments will be marked down 25% each class they are late; in particular, it is marked down 25% after the due date.

NO LAPTOP USAGE during class (If you NEED a laptop for note-taking then speak to me.)
