- I believe G+S did this. But this is a difficult experiment to run. "Most"
- 3SAT formulas are easy to solve. The tricky ones are excedingly difficult
- to find. And if you could find them (and prove you had a method for showing
- these were guaranteed to be hard) you might be better off trying to
- turn this procedure into a proof that P<>NP.
-
- What if the polynomial was O(n^6)? It would be hard to find data points
- for complex cases as n got above 10. How would you know you had O(n^6)
- performance and not just exponential time growth with a bit of error
- thrown in?
-
- Although I think that every author of a P=NP proof should have a
- running version of the algorithm, I still think it is hard to draw
- many conclusions from this. It shows that the guy can construct
- something that comes close, but it doesn't cut to the mathematical
- core of the problem. We already have neat algorithms that get close to
- the right answer on NP-complete problems like the travelling salesman.
- For all practical intents and realistic purposes, this is enough.It's
- really just an academic question now.
