THE P vs. NP QUESTION -- some further references!
If you wish to learn more about the P vs. NP question, here are two interesting papers:

"The history and status of the P versus NP question", by M. Sipser (Proc. of 24th annual ACM Symopsium on the Theory of Computing, p603-18 (1992))
available here: PvsNPhistory.pdf

"Guest column: "The P =? NP Poll", by William Gasarch (SIGACT News vol 33, p34-47 (June 2002))
available here: PvsNPpoll.pdf
This reports the results of a poll, asking many leading theoretical computer scientists their opinion on when and how the P vs. NP question will be resolved.
