In a DFA, for a particular input character, the machine goes to one state only. A transition function is defined on every state for every input symbol. One important thing to note is, there can be many possible DFAs for a pattern. A DFA with minimum number of states is generally preferred. Ability to transmit to any number of states for a particular input. If we compare both in terms of power, both are equivalent. For example, below is a NFA for above problem One important thing to note is, in NFA, if any path for an input string leads to a final state, then the input string accepted.
And you'd better bet that complexity theory and the world of topics that basic familiarity with complexity theory opens has more important applications. Cryptography, combinatorial optimization, approximation algorithms, communication complexity, machine learning theory, need I go on?
All I'm saying is that automata theory doesn't give the glimpse into theoretical computer science that every "introductory theory" textbook ought to.
I see your point but, from my limited experience, I've found the material on decidability crucial to get a good working grasp of many of the core abstractions central to both complexity theory and theory of computation in general such as languages, non-constructive proofs, reductions, etc.
I feel that without such exposure, it would be hard for a newcomer to appreciate the subtleties of the discipline Keep it up. Not everybody is coming from the same place. I was just looking for a freely available text that covered automata stuff, so I could brush up on a few things that I ran across reading an AI book.
This one caught my eye as being both very recent and licensed under a CC license, which is a sweet spot to me. Is it the best possible book for some particular class, or for any particular student? Who's to say?
But I reckon a few HN users might find this useful. The authors are two of my favorite profs from undergrad. The curriculum at the time had some problems. This book is written for a course that helps fix some of those problems.
So yes, this is written for people who have never written a proof before-undergrads in first or second year. From the title I thought it would be this one: It's also a good book so recommended, the part on automata is useful even for those not interested in theory, and being theory-averse myself, I didn't find it to be too dense although the later chapters certainly are.
I second this. The Sipser text was one of my favorites from my university career.
It's very short and covers a lot of material. There's no fluff at all, but it still manages to do a good job explaining the topics. Solid textbooks like that are very rare. It's one of only 3 books I elected to keep after the course was over the others being an assembly language reference and an intro to computer security. Guy is awesome https: It makes me sad to read the introduction and see that their course has become only an elective now.

Rylo Ashmore's office hours on Tuesday, May 28 have been moved to 12—1. Vijay Subramanya will be travelling May 13—17, so his office hours on Wednesday, May 15 will be cancelled. Assignment 1 has been posted below.
TA office hours will begin the second week of classes. To find my office, enter IQC on the ground floor of QNC, then take the wooden staircase up to the third floor—turn right and it's the second office on the left.
Alternatively, instead of the wooden staircase, you can use the elevator near the Ring Road entrance, close to the Student Life Centre.
