A practical introduction to essential topics at the core of computer science

Automata, formal language, and complexity theory are central to the understanding of computer science. This book provides, in an accessible, practically oriented style, a thorough grounding in these topics for practitioners and students on all levels.

Based on the authors’ belief that the problem-solving approach is the most effective, Problem Solving in Automata, Languages, and Complexity collects a rich variety of worked examples, questions, and exercises designed to ensure understanding and mastery of...

This book is intended to be used as a textbook for graduate students studying theoretical computer science. It can also be used as a reference book for researchers in the area of design and analysis of approximation algorithms. Design and Analysis of Approximation Algorithms is a graduate course in theoretical computer science taught widely in the universities, both in the United States and abroad. There are, however, very few textbooks available for this course. Among those available in the market, most books follow a problem-oriented format; that is, they collected many important...
