Catalog Description

CSE 4083 Formal Languages and Automata Theory. Presents abstract models of computers (finite automata, pushdown automata and Turing machines) and the language classes they recognize or generate (regular, context-free and recursively enumerable). Also presents applications of these models to compiler design, algorithms and complexity theory. Prerequisite: CSE 2010.

Overview

Why study formal languages and Automata?

• Practice abstraction, modeling and mathematical correctness
• Understand the nature of syntax
• Understand the nature of computation

Prerequisites

Mathematical sophistication is required, in particular discrete math. There will be no programming projects.

Textbook

The textbook for the class is:

Linz

Peter Linz. Introduction to Formal Languages, and Automata, sixth edition. Sudbury, Massachusetts: Jones & Bartlett, 2017. ISBN-13: 978-1-284077247

Other books are similar and cover the same material. In particular the book by Hopcroft, Motwani, and Ullman (HMU) is very similar, and sometimes used as the textbook in this course.

Lecture Notes

I think the ones by Busch are the best and I have provided Panopto recordings. Ullman's follows his own book, of course, and so are not focused on the way this class is organized. Linz' notes are not as extensive at Busch's. Each grid is cross-listed with Wikipedia articles which are often quite good on these topics.

• Lecture notes by Busch following Linz.
• Lecture notes by Ullman following HMU.
• Lecture notes by Linz following Linz.

Summary of Major Theorems

Chomsky Hierarchy

As a concise reference to the entire subject, we put some of the formal languages in the levels of the Chomsky hierarchy and summarize of the closure properties of the levels.
