My primary complaints, having spent a fair bit of time with it are exercise errata and proof readability. The proofs tended to be not so much terse as much as just having too much internal coupling. I needed to keep track of around twice as many details as necessary to follow the typical proof, requiring a half dozen rereads until I really understood what was going on.<BR/><BR/>Still a perfectly decent book! I only say a lot about it because the course I took used it. I've since given it a thorough but not quite complete readthrough. It's probably a step up from your typical graduate text. Be particularly wary of definitions contained in exercises, because that's where a lot of the exercise errata lie.<BR/><BR/>Hemaspaandra and Ogihara is targeted at a slightly higher level; I don't believe it's intended for a first course in complexity.<BR/><BR/>Someone mentioned Sipser, which is the other way around. It's targeted at an intro-to-theory course that would be a prereq for a course on complexity. Second edition is really nice, but I hear that first edition has excessive errata.<BR/><BR/>I don't know that much about the rest, as of yet.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1169516015428061472007-01-22T19:33:00.000-06:002007-01-22T19:33:00.000-06:00I am also very happy with what I've read of Arora/...I am also very happy with what I've read of Arora/Barak.<BR/><BR/>Related question--who (online or in print) has got the best problem sets and/or puzzles about or germane to complexity theory? <BR/><BR/>It would be nice if paper authors occasionally had the humility to say in the abstract, e.g., 'Theorems 4 and 5 could be proved by an undergrad', just to point people to opportunities to develop their chops.

You can also check out Goldreich's online lecture notes (which are less complete but possibly easier to read than his book if you already know the material). <BR/><BR/>Lance, I am curious why you would not use any other book for your course. Is what you teach really that different from, say, what is in Gooldreich's book?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1169493201698512442007-01-22T13:13:00.000-06:002007-01-22T13:13:00.000-06:00Why are you not going to write your own textbook a...Why are you not going to write your own textbook anytime soon ?<BR/>Are you too busy writing papers ?<BR/>(and blogging!)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1169486855327372552007-01-22T11:27:00.000-06:002007-01-22T11:27:00.000-06:00I also know the upcoming book by Arora/Barak but i...<I> I also know the upcoming book by Arora/Barak but it's still far from complete, would you recommend it for teaching? </I> <BR/><BR/>I used an earlier version of the Arora-Barak book for a course several years ago and I was very happy with it. (The course began with the polynomial-time hierarchy and students had already seen NP-completeness and basic space complexity.) It had a great selection of topics - though not all I wanted to cover, well thought out presentations that did not merely mimic the original papers, and far fewer bugs than more than just one of the published texts listed.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1169486535744923382007-01-22T11:22:00.000-06:002007-01-22T11:22:00.000-06:00Conspicuous by it's absence is ofcourse, Sipser's ...Conspicuous by it's absence <BR/>is ofcourse, Sipser's book.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1169481573640518212007-01-22T09:59:00.000-06:002007-01-22T09:59:00.000-06:00Yes, of course.
