Computational Complexity

Computers and Tractability

  • rating: classic

The classic work presenting a compilation of many NP-complete problems.

Computational Complexity (Papadimitriou)

  • rating: 1

Really quite good book on the subject. One memory I have from it is the economical definition of Turing machines; they're defined as a 4-tuple (in contrast to other author's definitions using, say, a 7-tuple); another is the discussion early on of what metrics can be used for complexity and what can't, and how one can define pathological metrics.

Computational Complexity (Wagner and Wechsung)

  • rating: TODO

Gosh, this is incredibly heavy. It's hard to imagine any individual ever owning this book; I can only imagine it belonging to a university library. That sort of book.

Why Philosophers Should Care About Computational Complexity

  • rating: 3

There's some good stuff here, but it's not all good stuff.

Mainly, this is where I discovered Cobham's P-complete formulation. It comes via another paper via another paper though, so it should really be described there.

There are a few other interesting things in this essay though. The "waterfall as computation" example, for example.
