Description:

An Introduction to Formal Languages and Automata, Sixth Edition, provides an accessible, student-friendly presentation of all the material essential to an introductory Theory of Computation course. Written to address the fundamentals of formal languages, automata, and computability, the text is designes to familiarize students with the foundations and principles of computer science and to strengthen the students ability to carry out formal and rigorous mathematical arguments. The author, Peter Linz, continues to offer a straightforward, uncomplicated treatment of formal languages and automata and avoids excessive mathematical detail allowing students to focus on and understand the key underlying principles.

New and Key Features of the Sixth Edition:
 
  • An accesible approach allows students to clearly understand key content while retaining the appropriate mathematical notations and theorems requrired for the course
  • New Chapter Synopses, found at the beginning of each chapter, recap important concepts found in the text
  • Every major idea is preceded by a motivating example, drawn from applications, that introduces the concept and illustrates its usefulness
  • New Exercises added throughout are more closely tied to examples in the text
  • An enchanced Instructor's Manual includes more detailes solutions to all problems found in the text

Target Audience:

Written to address the fundamentals of formal languages, automata, and computability, An Introduction to Formal Languages and Automata provides an accessible, student-friendly presentation of all material essential to an introductory Theory of Computation course.
