What are the most recent (say in the last 3 years) attempts at disproving $P = NP$, and where can I find the papers?

    $\begingroup$ I assume the downvotes (not me) because most such attempts have an obvious flaw in them and do not really add to our understanding of the problem. $\endgroup$ May 29, 2019 at 15:15

The last such serious attempt was likely Norbert Blum's attempted proof of P $\neq$ NP in 2017. Not long after it was submitted to arxiv, it was discovered to have a serious (but nontrivial) flaw.

This proof was discussed on stackexchange here (and in more detail here), and on several blogs (like Godel's Lost Letter).


Gerhard Woeginger has an up-to-date page with all attempts to (dis)prove the P vs NP question: https://www.win.tue.nl/~gwoegi/P-versus-NP.htm

    $\begingroup$ @Yamar69 If you already knew about this page, you should have mentioned it in the question. $\endgroup$ May 29, 2019 at 15:43

    $\begingroup$ This important page is now gone - it is replaced with a redirect to link.springer.com/article/10.1007/s10951-022-00748-4 $\endgroup$ Nov 11, 2022 at 11:13
  • $\begingroup$ The page is back, but obviously unmaintained. Did anyone take over the updating of such an archive? $\endgroup$ Feb 16, 2023 at 11:35
  • $\begingroup$ Here is a fairly new try … arxiv.org/abs/2302.09512. $\endgroup$
