Discussion Overview

The discussion revolves around a paper proposing a solution to the P vs NP problem, specifically addressing whether the claim that P does not equal NP is valid. Participants explore the implications of the paper, its credibility, and the reactions from the broader scientific community.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants express skepticism about the validity of the proof, suggesting it may not hold up under scrutiny.
  • Others highlight the credibility of the author and the potential significance of the results if proven true.
  • A participant notes that the paper claims to use CNF-DNF-approximators to establish exponential lower bounds, which they interpret as implying P ≠ NP.
  • There are references to previous results and the collaborative nature of scientific progress, indicating that the current claim builds on earlier work.
  • One participant mentions a second version of the paper that claims the proof is incorrect and promises to elaborate on the mistakes found.
  • Another participant provides links to discussions questioning the validity of the proof, indicating ongoing debate in the community.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of the proof. There are competing views regarding its credibility and implications, with some expressing confidence in its significance while others anticipate flaws.

Contextual Notes

Some participants reference external discussions and critiques of the proof, indicating that the evaluation of the paper's claims is ongoing and may depend on further elaboration of identified mistakes.

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
