# Reducing the P vs. NP Problem to the 3x + 1 Problem

Abstract: The relationship between P and NP is a key issue in computer science.

Though people have known that $P \subseteq NP$, whether P equals to NP is still uncertain.
This paper finds that the P and NP problem is strongly related to the 3x + 1 problem.
According to this finding, this paper demonstrated an example showing $P \neq NP$ under two conjectures.
This paper firstly proposed a co-line problem based on the 3x+1 problem,
then proved that the co-line problem can not be solved by the deterministic algorithms
in polynomial time, and can be solved by a non-deterministic algorithm in polynomial time.
This example showed that P is the proper set of NP, i.e., $P \subsetneq NP$, thus, $P \neq NP$,
if two conjectures on the 3x + 1 problem hold.

Comment: This is a test for posting a spicy blog article. On one side, I think we have finished the proof. On the other side, I think everyone will think it a joke. So I will examine this paper one time again. Think it a joke, please.
