I thought AI was declared dead in the 80s of the previous century Declared dead by who? What were they referring to by AI? As for the P = NP problem, I found the following description: A major unsolved problem in computer science is the socalled P=NP problem: machines are considered in which there is a certain amount of freedom in choosing the next step in a computation (such machines are called nondeterministic). By making good guesses (or choices) one can often obtain a quicker computation than by systematically working through all possible cases in a deterministic way. The P == NP problem asks whether every function computable on a nondeterministic machine in polynomial (i.e., tractable) time is computable in polynomial time on ordinary (deterministic) machines. Everything that can be invented has been invented.  Charles H. Duell, US Commissioner of Patents, in 1899. Update: I've found several papers on the subject including Is the NP problem solved?. Haven't had a chance to read through them yet, but they look interesting. Update 2: A short introduction to quantum computation In reply to Re: Re: Artificial Intelligence Programming in Perl
