Automata Theory, Languages, and Computation 3 rd Edition hopcroft_titlepgs 5/8/06 12:43 PM Page 1. The main source of this knowledge was the Theory of Computation commu-nity, which has been my academic and social home throughout this period. Research on formal models of computation was initiated in the 1930s and 1940s by ... many introductory theory courses today con- Theory Comput. Online archive and submission instructions. Complexity. INTRODUCTION TO Automata Theory, Languages, and Computation JOHN E. HOPCROFT Cornell University RAJEEV MOTWANI Stanford University JEFFREY D. ULLMAN Stanford University 3 This book is an introduction to the theory of computation. To Patricia, Christopher, and Timothy. With the help of a University Teaching Fellowship and National Science Foun-dation grants, I developed a new introductory computer science course, tar-geted especially to students in the College of Arts & Sciences. A compu ter is an elect ronic device, ope rating under t he control o f instructions sto red in its o wn memory. After a chapter presenting the mathematical tools that will be used, the book examines models of computation and the associated languages, from the most elementary to the most general: finite automata … The the- ory that evolved has been used to explain human expe- rience and to suggest how artificial computing devices should be … Time T A(x) is used (depending on the context) as All three of these sources have influenced the presentation of the material in Chapters 7 and 8.

This course was These notes are an on-going project, and I will be grateful for feedback and criticism from readers. Distributed computing systems continue to rise in prevalence; networks of work-stations and clusters of personal computers hold the promise of increased power and price=performance ratios. computing and the reason everyone should learn it. We use the following measures of computing resources of a machine Aon input x: Time: The greatest depth D A(x) of causal chains is the number of computation steps. Computability theory became possible once precise models became available for modeling the common- place phenomenon of mechanical calculation. computers s cience and computing in general.
