God-level Xueba system

After entering the bedroom, Yan Xin turned on the alien computer and logged into Gouya Live.

Alien's computer is different, it only takes five seconds to start up!
The last live broadcast was in the morning, and there were basically no big anchors at that time, but it was different at night!
After [-]:[-] p.m., Gouya’s live streams have the most traffic, and the popularity of each major anchor has reached several million. After all, everyone has finished get off work and dinner at this time, and the rest of the time is naturally for relaxation.

Yan Xin clicked the broadcast button, then pointed the main camera at herself, and the secondary camera at the draft paper.

It's only been less than 3 minutes since the broadcast started, Yan Xin hasn't spoken yet, and the popularity of the live broadcast has reached more than 500 million in an instant!
"I'm coming!"

"Has Xueba started the live broadcast again?"

"Isn't it going to be about np completeness this time?"

"Although I don't understand it, it's so cool to watch the anchor pretend to be serious!"

"Little Mazar is ready!"

"I'll give a reward first!"

Chick only rewarded the anchor with a luxury yacht for flirting with girls!
I just wore a booster pad and tipped the anchor fifty blood bottles!
Gouya Live Backstage.

Zhao Long clicked on Yan Xin's live broadcast room, seeing the popularity of the live broadcast room soaring, Zhao Long nodded in satisfaction.

Not bad!

Yan Xin also kept his promise, as soon as he signed the contract, he immediately started the live broadcast.

And less than 10 minutes into the broadcast, the popularity value displayed in the background has already reached the top ten!
"Good evening, everyone! I'm Yan Xin, and I'm very happy to start the live broadcast again! Before the live broadcast, I have something to say in advance!"

Yan Xin thought it would be better to talk about the academic column first.

In this way, when I am not live broadcasting, other small anchors can follow the trend of live broadcasting, so that the academic column will become more and more popular!

"I have reached an agreement with the Gouya backstage! It is estimated that the Gouya app will be maintained tomorrow! After that, I will open a new live column in the Gouya backstage: academic! I hope that interested anchors in the live broadcast room can actively participate and expand this New live column!"

"What the hell? Anchor 666! Has he become a minority shareholder of Gouya so quickly?"

"New column? I must participate!"

"I have to study hard, maybe one day I will be as popular as the anchor!"

"I really didn't expect that in this era of rapid information development, webcast learning has become so popular!"

"When a new column is opened, I will go live too!"

There are many small anchors in the live broadcast room, but Yan Xin found that the effect is not very good!

Whoops!
Yan Xin patted her head, I'm really a fucking loser!
I haven't started pretending to answer the world's problems yet. Naturally, the popularity is not high. It would be great to talk about it when there are more people in a while!
Yan Xin quickly spread out the straw paper, picked up a pen, and prepared to explain the np complete question!

"Now I will explain to you how to solve np complete problems! First, I will popularize what np complete problems are! The full name of Np complete problems is Non-deterministic Polynomial problems, that is, non-deterministic problems with polynomial complexity. Simple Written as NP=P? This question is much easier to understand than the Riemann Hypothesis! The question is on this question mark, is NP equal to P, or not equal to P?"

"I dont understand!"

"What the hell? It's either equal or not. How can there be two situations in one formula?"

"Yes? Can you be more popular?"

Yan Xin smiled, sure enough, many people still don't understand what this means.

Then take out the few examples of changing thinking that I prepared before and talk about it!
"Well, let me give you an example and everyone will understand! Suppose you just entered college and you are going to hold a freshman welcome party! Everyone is eating, drinking and having fun in the restaurant! But you are not familiar with this group of people at all, and the people and names are not at all familiar. I'm sorry! But your homeroom teacher rushed over at this moment and asked you to find someone named Zhang Yida, among the vast crowd, you definitely don't know who it is!"

"If you don't have a goal, you can only ask one by one! But if your teacher tells you that the one who drinks the most and wears a yellow plaid shirt is Zhang Yida, can you lock him in an instant and put him He brought it in front of your head teacher? That's right, the np complete problem can also be understood in this way!"

"If you don't understand, I can give another example! You should have experienced it yourself. When we are doing math problems, the problems we like to do most are application problems and calculation problems, and the most annoying are proof problems! This Why? Because the proof question has already given the answer, what we have to do is to use the existing knowledge to prove whether it is correct! And the steps will become more and more complicated, causing many people to have no idea to start! This is also A kind of inertial thinking when everyone is doing math problems!"

This sentence suddenly made the barrage go crazy, it really touched everyone's heart!
"Damn it! The anchor is right! What I hate the most is doing proof questions! It gives me a headache just watching it!"

"Who isn't! The most annoying thing is to verify whether a sequence of numbers is convergent or divergent! It's better to do a calculus!"

"Skip the proof questions of my advanced mathematics!"

"Almost! I didn't write one of the advanced mathematics proof questions in the postgraduate entrance examination, but fortunately I was admitted to a graduate student!"

"Brilliant!"

Yan Xin couldn't help laughing.

When I was a scumbag before, I really didn't care about this.

After all, in the eyes of scumbags, there is no difference between proof questions and calculation questions.

Not at all!
"This shows that it is difficult to verify a problem with a known result. Similarly, if someone tells you that 13333452 can be written as the product of two adjacent numbers, you may think that this person is bragging! But if He told you that 13333452=3651*3652, then you can simply verify it with a calculator and find that this is correct! From this, most scientists boldly speculate that all complete polynomial non-deterministic problems can be converted into a class called satisfaction Logical operations of problems. Since all possible answers to such problems can be computed in polynomial time, people wonder whether there is a deterministic algorithm for such problems that can be directly calculated or searched in polynomial time How about the correct answer? This is the famous NP=P? conjecture!"

Yan Xin thinks that by giving an example like this and explaining it to everyone by changing their thinking, maybe they can better understand the np complete problem.

After all, it is not easy to simplify world-class mathematical problems into common sense problems in life!
Alas, my heart is broken for these scumbag viewers!
But what Yan Xin cares most about is naturally the 5000 points in the system!
