SUMMARY

The discussion centers on Norbert Blum's 2017 paper claiming P ≠ NP, which utilizes CNF-DNF-approximators to establish exponential lower bounds for the monotone network complexity of specific functions. Experts express skepticism about the validity of the proof, with references to potential flaws highlighted in subsequent discussions. The consensus leans towards the belief that the proof may not withstand scrutiny, as indicated by ongoing debates in the theoretical computer science community.

PREREQUISITES
  • Understanding of computational complexity theory
  • Familiarity with CNF-DNF-approximators
  • Knowledge of monotone and non-monotone network complexity
  • Awareness of the significance of the P vs NP problem
NEXT STEPS
  • Research the implications of Blum's proof on the P vs NP problem
  • Examine counterexamples to Blum's claims, particularly Tardos' function
  • Study the methodology behind CNF-DNF-approximators in depth
  • Explore the historical context and previous attempts to resolve the P vs NP question
USEFUL FOR

The discussion is beneficial for theoretical computer scientists, mathematicians specializing in complexity theory, and researchers interested in the P vs NP problem and its implications in computational theory.

What can the experts decipher on this:

Is this going to win a million dollars?

EDIT: The punchline is P =/= NP

I'm not an expert, but from what I heard, the author is a credible researcher and the paper seems to look good. We'll see if someone finds a flaw.
 
If it is true, then it will be a sensation and I wonder, why the usual pop-science shout-boxes haven't reacted yet. Also interesting would be, whether Blum will also refuse to grab the million, as Perelman did. What looks promising is the way itself:
Berg and Ulfberg and Amano and Maruoka .. have used ... to prove exponential lower bound ...
and
We [Blum] show that these approximators can be used to prove the same lower bound for ...
This is the way science works: A great result from one author(s), because non-trivial lower bounds are really hard to prove, and another one generalizes the result. And as with Poincaré, the result ##P \neq NP## is simply a corollary.

It's probably not as sensational as P=NP :-)

Thoughts, PF? I know very little about the subject—in fact, the abstract makes my eyes bug out:

Berg and Ulfberg and Amano and Maruoka have used CNF-DNF-approximators to prove exponential lower bounds for the monotone network complexity of the clique function and of Andreev's function. We show that these approximators can be used to prove the same lower bound for their non-monotone network complexity. This implies P not equal NP.
 
There is now a version 2 - where it is claimed:
The proof is wrong. I shall elaborate precisely what the mistake is. For doing this, I need some time. I shall put the explanation on my homepage
