The pinnacle of human ingenuity,

Xu Mang had already reached the intelligence level at the top of the system, but he didn't seem to notice any feeling of intelligence improvement, and searched the inventory in his mind, and found that he still had some knowledge, and these were all copied from the first four levels.

Don't...

Are there any books in this world that humans don't know yet?

Xu Mang thought about this question, he felt that he was being tricked by the system... I tried my best to get to the fifth level, but there was no change in the result, and I don't know where this fifth level is, it stands to reason that the fourth level is the top of the existing scientific field, and the fifth level is the top of the universe.

Outcome...

It's complete!

"What's the situation?" Xu Mang was lying on the bed in the hotel, his mind was blank at the moment, he didn't know what was inside, silently... He fell asleep, and five minutes later, he was suddenly surprised, and hurriedly took out his notebook and found the NP completely problem.

This is a non-deterministic problem about the complexity of polynomials, and its difficulty is known as one of the world's seven major mathematical problems, some calculation problems are deterministic, such as addition, subtraction, multiplication and division, etc., as long as they are deduced according to the formula, step by step, the result can be obtained.

But there are some problems that can't be calculated step by step, such as finding large prime numbers... The answer to this kind of question cannot be calculated directly, but can only be obtained through indirect guessing.

This kind of problem usually has an algorithm, which cannot give a direct answer, but can give whether the result is correct, which is called a polynomial non-deterministic problem, and if all the possible answers to this problem can be checked in polynomial time, it is called a complete polynomial non-deterministic problem.

All completely polynomial non-deterministic problems can actually be converted into logical operation problems, so... A conjecture was born as to whether there was a deterministic algorithm for such problems.

Calculate the answer directly in polynomial time?

And Xu Mang knows,

In fact, as early as ten years ago, a professor announced that he had proved that P!=NP... But less than two weeks later, mathematicians came up with an answer that the paper could not be found.

In another field, computer science, most computer science experts don't believe in P=NP, and a computer science expert from the Massachusetts Institute of Technology wrote a paper listing ten reasons why it doesn't exist.

Thereinto... Xu Mang was very impressed...

If P=NP, the world will be fragmented, all creation will become unintertwined, there will be no fundamental gap between solving the problem and agreeing to the solution... Anyone is a Newton, and everyone can be Gauss or Euler.

truly

If this problem is solved, it will completely upend the technological and economic foundations of the current society... But if this problem is solved, it could become an innovation boost that is even more significant than the invention of the Internet, and this is no joke.

"Ugh..."

"Damn... I thought that when my intelligence was raised to level five, there would be a new breakthrough, but it didn't seem to have changed..."Xu Mang sighed, feeling a little regretful in his heart, if the upgrade card is used for physical strength, will Xiao Man still be rampant?

No, it won't!

Joke... Exercise twice a year, once for half a year!

...

About Xu Mang's third Nobel Prize in Physics, it has caused a huge sensation in the world, after all, this is an unprecedented event, no one has reached such a height before, and I believe that Xu Mang will not surpass Xu Mang in the future.

For Huaguo... When Xu Mang once again occupies the focus of the world's peak, it is the highest apex of science in the whole country, three Nobel Prizes in physics, one Fields Medal, one Abel Medal, etc., he is a scientist among scientists, he is a legend within legends.

It's just that

Even legends will say goodbye, but Xu Mang once said... He can hold out for half a century, maybe he is not perfect in the eyes of others, but he is complete enough... No one has been able to do what he did.

On this day,

Xu Mang returned to the magic capital with honor, there was no welcome occasion, and no one knew that he had returned, the same as before... He left quietly and came back quietly, with sunglasses, a mask and a hat, and no one cared about this very serious young man, the greatest scientist in the world.

Chen Xi had been waiting at the exit of the airport for a long time, and when he saw Xu Mang alone, he couldn't help but feel helpless... To be honest, there are many people in society who compare Brother Xu Mang with those stars, and even directly compare fame and fortune.

It's too superficial!

As a senior executive of Xu Yang Technology Company, Chen Xi has dealt with many scientific research workers, those people are engaged in research, do learning, and many times focus on a thing that no one knows about all their lives.

Their stage is the research room and the laboratory, where there is no spotlight and fans hugging each other, and their happiest moment is that their research has achieved results.

sometimes

Only they applauded themselves, because few people understood what he was doing, but they were happy because he proved his worth with his results.

"Brother!"

"I found that every time you come back, it's a person..."Chen Xi took Xu Mang's suitcase and said with a smile: "If something goes wrong, this is a big deal, last time you were pushed by others, and other companies almost went bankrupt." ”

“...”

"It was an accident. Xu Mang waved his hand and said with a wry smile: "Take me to dinner first... Starve me to death. ”

"Good!"

moment

The two came to a very high-end cafeteria, Xu Mang came up and made a bowl of egg fried rice first, and then he was full... The people around him were stunned, after all, this restaurant charges a lot, and as a result, this person ate a bowl of egg fried rice.

If before... Xu Mang may open the system to untie the belt and eat to death like crazy, but now he can't do this, the position determines a person's behavior, and many things Xu Mang can only look at or think.

“...”

"Brother... You're going too far!"

"Began to threaten to be hungry ... As a result, I spent nearly a thousand yuan and ate a bowl of egg fried rice. Chen Xi saw Xu Mang sitting on a chair playing with his mobile phone, and couldn't accept it for a while, so he said helplessly: "Brother... Do you do the same at home? My sister cooks a lot of dishes for you, and you only eat instant noodles?"

"Crazy?"

"How dare I do this in front of your sister, do I want to live?" Xu Mang said angrily: "Anyway, lend me a little money." ”

“...”

"I don't dare... Xiaoqiong and I were both warned by my sister that if I lend you another penny, I want the two of us to look good. Chen Xi shrank his head and said cautiously: "Brother Chen Fan and a few of them have also been warned, as long as they dare to give you a penny, their company will be destroyed." ”

I...

it!

What's going on?

Xu Mang said with a black line on his face: "I rely on... This... Haven't you been beaten?"

Chen Xi pursed his lips, as the person who has been following Brother Xu Mang and Sister Xiaoman, he knows the most about this couple... As long as Sister Xiaoman is angry, Brother Xu Mang can only stand aside, and then nod his head.

But there is one thing to say,

As long as something happens to Brother Xu Mang, Sister Xiao Man will become very nervous.

Long

Chen Xi sent Xu Mang to the house, and left in a hurry alone, and the moment he opened the door... Xu Yang and Xu Man, who were watching TV, hurriedly turned their heads... As a result, when they saw their father standing at the door, the two little ones were not calm, and hurriedly climbed down from the sofa, twisting their little buttocks and running towards their father.

"Oops~"

"My little darling... Do you miss your father?" asked Xu Mang with a smile.

The sister and brother didn't speak, and they proved how much they liked their father with their actions, kissed him directly on the face a few times, and then the tender little face kept rubbing his father's cheeks.

“...”

"Are you back?" Yang Xiaoman came out of the kitchen, and when he saw the two little guys so tired of his husband, he felt very angry, and said, "Two little bastards... I only have my father in my eyes, and my mother works hard to make money, and she is not grateful to me at all. ”

Facing his jealous wife, Xu Mang could only smile, he couldn't decide who the child liked, but the child wouldn't lie.

Followed by

Xu Mang accompanied the children to watch cartoons, but his mind was full of questions about the fifth level of intelligence of the system, and what should he do to reflect the concept of the fifth level of intelligence.

Then

Xu Mang took out his mobile phone, clicked on the email APP, found the email sent by the University of Science and Technology before, clicked on it and re-read the question about the distribution of thousand-kilometer-level quantum keys.

presently

In fact, this problem can't be solved, at least Xu Mang feels that it is impossible to solve it when he is the fourth level of intelligence, and the reason why he said that it will be solved in a week is completely based on the upgraded ability, and the result...

This...

What should I do?

How to pick up the cow that was blown out?

"System?"

"May I ask what's so special about Level 5 intelligence?" Xu Mang asked inwardly.

[Automatically receive new knowledge]

[Comprehensive analysis of current issues]

[Requirements: Top level in the current field]

WTF？

What the heck?

Dude didn't receive any knowledge!

Then

Xu Mang looked at the information sent by Professor Yuan and fell into deep doubts... Quantum communication belongs to a new research field that combines quantum theory and information theory. is its own strength, and information theory belongs to the category of statistics, and this aspect... Xu Mang is still only at the expert level, and there is still a little distance from the top.

"Wife!"

"Do you know information theory?" asked Xu Mang.

"Get out!"

"The old lady doesn't know!" Xiao Man, who was doing yoga on the side, glanced at him viciously, and then continued to do the next moves.

Helpless

Xu Mang silently picked up the tablet on the coffee table and bought a few professional books on information theory on the Internet, but... He had just clicked on the book, and a whole new world had taken place.

it!

What an awesome thing this is!
