Why Most P vs. NP Attempts Fail
Easy Theory
Here we give some explanations as to why every P vs NP proof has failed, so far. P refers to problems that are solvable in polynomial time, and NP are those that can be checked in polynomial time. A central question in complexity theory is: does P = NP? It is sufficient to show that some NP-hard problem is in P (to show that P = NP), or to show that EVERY NP-hard problem is not in P (to show that P != NP). It is also not ruled out yet that the statement "Does P = NP?" is impossible to solve with current mathematical techniques (or any slight variation).
I give a set of reasons for why known "proofs" have failed, so that you can see through why a "proof" is actually false; many people claim to have solved the problem online. I deliberately did not go into details because the video would be insanely long if I did (if there's interest, I can make such videos...eventually...). The truth is: it is unlikely we will see a resolution of P vs NP soon, or even within our lifetimes, because it is so insanely difficult for some of the reasons I go into in the video.
