An Introduction to Formal Languages and Automata Hardcover – 1 October 2000

Very good! A+++! Recommend and would buy again!

Rarely used the book but cheap and helped a little... For a boring class not much else to say then that

A great deal of required reading. Text while being required, has a great level of depth on the subject matter. Since this is a text book for class, this is the only one that I have read on this topc.

The book was required for a course, and I found it to be pretty straightforward, if a little dull. It's written at a simpler level than Sipser or Hopcroft and Ullman, which might make it appropriate for someone who is a little apprehensive about the topic (although I think both of those are better books). My biggest complaint was that after finding the first two errors in the text (in an exercise solution and an example), I wasn't comfortable trusting the book to tell me what it meant. The errors were listed in the errata, so if you're using the book, print out a copy of the errata, and mark your book up. Finding these errors for yourself is a good test of your understanding, but it's also more pain than necessary. Use with caution.
