Title: This book is not useful in the understanding of Automata.
Product review: I had to purchase this book for a required class in Computer Science. I don't understand how a book that has soo many bad reviews could be required for a class. I checked some of my answers with the Instructor's solution manual and even the manual was useless. For example, the answer for section 3.2 #1 says "Routine application of a given contruction". NOW, DOES THIS ANSWER HELP YOU? Don't think that this is the only answer like this, most of the answers in the manual are similar. No one even knows who the author's audience is... I think people who buy this book is because it's a requirement. I think that every University that requires this book should think it over.
Would you say this review depicts the product in a flattering or unflattering light?
