What would happen if it were solved /sci/? Would the singularity occur?

Let's say i solved the traveling salesman problem. Does this imply in P=NP?

I'm not OP.

Meaningless garbage. State your question intelligently or >>>/g/tfo

>> No.6760451

P = NP

divide by P;

So we have, N = 1.

SOLVED.

>> No.6760452

Why do you fucks keep making these troll threads? This is easier to solve than that stupid .99999 = 1 stuff.

P != NP whenever N != 1

That is literally it.

>a problem can be quickly verified

NP problems are NOT known be verifiable quickly by a computer if the answer is in the negative.

NP≟coNP is still an open question even if P≠NP≠AP

No.
And your mom solves the traveling salesman problem in polynomial time every night when she visits every state to find a large enough condom for me.

It was solved within the past year.

Ill prove the fucking collatz conjecture and then ill show you faggots that P == NP along with proving the twin prime conjecture

either that or ill die trying

Did you even bother reading the shit you linked?

>> No.6761269

It's a question mostly of theoretical interest. A polynomial-time algorithm is only guaranteed to be "efficient" in a purely mathematical sense. Suppose we found a polynomial time algorithm for solving TSP but it ran in O(n^94982389340892938690823689023869082309869038092389068908326) and had huge constant factors. That's a polynomial time algorithm but the naive O(n!) algorithm would be faster on all realistically solvable inputs, and even then, you'd just be better off using approximation algorithms.

With a large enough set that polynomial algorithm will run faster than the other one!

How does p=/=np effect RSA? Isn't guessing a password the equivalent of the lottery? Randomly guessing at something you no information for. With np-complete problems you have a problem which you have to solve, with passwords you have no problem, you just have an input field and you have to guess the input.

>> No.6761896

fuckin nerds

>> No.6761921

>>6761350
You can sniff the code which is effectively:
define:
C = password in numbers (so a would be 1, b would be 2...)
P1= extremely large prime which is public
P2 = another extremely large prime which is hidden

They tell you P1 and your computer sends x=mod(C^P1,P1) to them. And they take this and do mod(x^P2,P2) which equals C.

if P=NP, then there is a function in polynomial time that can extract C from P1 without knowing the unlocking key P2. Current brute force just tries every single combination (which is in exponential time).

problem - increase n by 1000000000000000
found solution - add 1 to n 1000000000000000 times

no/depending on the algorithm you use
