Course Description: Formal approach to automata theory; finite state machines, regular expressions, regular languages. Develops mathematical foundation for Computer Science.
Course Goals: At the end of the course, students are able to
  1. Understand and manipulate formal descriptions of languages, automata and grammars with focus on Regular and Context Free Languages, Finite State Automata and Regular Expressions.
  2. Apply rigorously formal mathematical methods to prove properties of languages, grammars and automata.
Prerequisites: MATH255, CS202

0-49 F
Academic Integrity: Students are allowed and encouraged to discuss reading materials with each other. However, homework assignments must be solved and written individually. If you obtain a solution with help then you should acknowledge your source in the paper and then write independently your own solution.

Cheating will not be tolerated. Cheating on any assignment or exam will be taken seriously. All parties involved will receive a grade of F for the course and be reported to the Academic Senate.

General Policies:
  • Makeup Exams: No.
  • Homework Assignments:
    Homework assignments should be written neatly on standard sized paper (8.5 x 11 inch), possibly in black or blue ink (please do not use red) and submitted at the due date (no electronic submissions accepted). Each page should be numbered. Late submissions will not be accepted.
  • Use of Cell Phones: forbidden.
  • Late arrivals:
    Students arriving 30min after the beginning of class will not be admitted.
  • Office:
    Students are warmly invited to visit the instructor (during the announced office hours) for questions and clarifications.
  • E-mail:
    E-mails addressed to vcrespi@calstatela.edu must have, in the subject, the keyword CS386 (e.g. Subject: CS386 ...). All the E-mails will be possibly processed in the evening and so will be answered with a minimum delay. Be careful, the keyword in the subject is important for automatic filtering. Wrong subjects may result in the accidental loss of the message.
