[agi] Re: [agi] P≠NP

2010-08-16 Thread Matt Mahoney
Does anyone have any comments on this proof? I don't have the mathematical 
background to tell if it is correct. But it seems related to the idea from 
algorithmic information theory that the worst case complexity for any algorithm 
is equal to the average case for compressed inputs. Then to show that P != NP 
you would show that SAT (specifically 9-SAT) with compressed inputs has 
exponential average case complexity. That is not quite the approach the paper 
takes, probably because compression is not computable.

This is a very powerful argument, but is not quite a rigorous
proof. Thermodynamics is like saying that because all zeros below 10^20 have
a real part of 0.5 therefore there are no non trivial zeros for which that
is not the case. What I am saying is pedantic, very pedantic but will still
affect Clay's view of the matter.

You will *not* be able to decode Blackberry, of course.
