Mathematics is a fundamental subject, and it can even be said that it is the foundation of all modern civilizations.

If there had been no mathematics in this world, then the current human civilization would probably still be in the primitive era of mushrooms and hairs drinking blood. Well, at most, ancient times who would make fires and use tools.

But the basics don't mean the simple.

In fact, mathematics is also the most difficult subject in the world, and it is related to everything in the universe.

It is no exaggeration to say that if human beings can find all the mathematical problems that can exist in the universe, solve them one by one, and build the most correct mathematical models, then human beings have part of God's ability to predict the past and the future.

The P/NP problem is such a mathematical puzzle.

It ranks first among the seven mathematical problems of the millennium, and no one has been able to prove it from the date of mathematician Steven Cork's proposal in 1971 to the present, whether it is forward or backward.

Even if there are mathematicians who forcibly prove it, it has never been recognized by popular mathematicians.

For ordinary people, 90% of them have never heard of this question, and 99.9% of people will only say with a confused face after seeing this question: "Ma Dan, what is this winding question trying to express?"

Of course, in fact the problem can be expressed very simply: P=NP?.

This question mark is the essence.

Is it equal or not?

In the most layman's terms, if one can verify the correctness of the answer to a problem in polynomial time, can one solve it in polynomial time!

You can't even understand the popular explanation, right?

Do not doubt your own IQ, in fact, the author himself does not understand.

It is said that 85 percent of mathematicians vote that P is not equal to NP!

But it can't be proven.

However, such a problem is closely related to people's lives.

This is a problem related to computers, and it is also an issue that can be widely used in the military, people's livelihood, the Internet, artificial intelligence, and other industries closely related to ordinary people.

If this problem is solved and a complete mathematical model is successfully made, many mathematical problems that once needed to be solved by exhaustive methods will be solved, and new algorithms can be written, which will greatly save computing power, thereby promoting the scientific and technological progress of the whole world.

So Don Pudding's statement that the key steps on this issue are worth a trillion dollars is really not an exaggeration. Of course, the premise is that this step can really prove that P=NP is true.

But unfortunately, as I said before, whether it was the operator who called the police or Lin Jianjian who was standing across from him, they belonged to the 90% of the people, and they didn't know anything about the so-called P vs. NP problem.

There is no awareness of the seriousness of the problem.

Don Pudding knows this.

So after reminding the police operator that their call records had been recorded, the matter was really serious, and if it was not dealt with in time, it would probably have a great impact, and Tang Pudding simply hung up the phone.

Then he ignored Lin Jianjian on the other side and opened Weibo with his mobile phone.

True, the average person does not understand the importance of this issue and has not even heard of it.

But there are still people who understand this problem after all, and what is even more terrifying is that the group that has a deep understanding of this problem and knows a lot about the importance of this issue, although they generally don't like to be more serious with others for small things in their daily lives, but if this group really wants to be more serious about something......

99.9 percent of the people can't afford to provoke it!

So at this time, Tang Puding, who opened Weibo, began to solve the problem......

That's right, after successfully proving the Poincaré conjecture using pure topology, the thing is back to solving mathematical problems.

The difference is that last time he was on a relatively high-end mathematical forum, and this time he was on Weibo with the Internet as the carrier; last time he needed to completely solve the whole problem, but this time he only needs to show genius creativity, so that 80% of the world's mathematicians can see the hope of proving the problem, and then at the most critical time, it comes to an abrupt end......

That's what Don Pudding thought, and that's what he did.

Hands are quickly typing on the mobile phone, completely ignoring the surrounding people watching the excitement There are more and more people......

Pick only the most brief inputs, strings of mathematical symbols, concepts, theorems......

Ideas, you only need to prove the idea step by step, and then arrange a key node......

Tang Pudding accompanied several pictures of the car accident that had been prepared for a long time, and gave a brief explanation: "I was sitting in the car, and the sudden inspiration made me full of confidence in proving the problem of P=NP!"

"That's right, I felt like I had this problem within my reach, and then at that moment, a Ferrari suddenly stopped and the car I was in crashed into it unexpectedly, and it was only because my driver gave way to pedestrians at the zebra crossing!"

"Of course, none of this matters, the important thing is that my inspiration is gone! it comes and goes, I stretch out my hand, but I can't hold it for a moment......"

"My train of thought was suddenly interrupted here, and I don't know if the inspiration about P=NP will come again in my lifetime, and I may not even live that long, because just now, the perpetrator pointed to my nose and told me that he has 10,000 ways to make my life worse than death, and I have nothing to do. ”

"His name is Lin Jianjian, I don't know him, I don't know what background he has, and he is a person with many statuses! After all, I am just an ordinary person with an ID card. Or rather, just a math and computer enthusiast with an ID card. ”

"So that's all for today's problem, the traffic police are coming, but so what? My inspiration is gone! If my solution idea can bring inspiration and solve this problem, I will be very happy. That's it, goodbye, everyone!"

......

In fact, when Tang Pudding called, Lin Jianjian was a little drumming in his heart......

Of course, it wasn't that he didn't believe Tang Puding's nonsense, but that he suspected that this guy was a little mentally abnormal......

After all, a normal person can make up such nonsense when he calls the police?

A broken Ford with tens of billions of dollars worth of lab equipment?

A question worth trillions of dollars?

Listen, is this something that a normal person can say? Further, is this a human being?

The barefoot one doesn't wear shoes, but he's the one who wears shoes.

At this point he was furious, but he was the only one in the car.

If Don Pudding really went crazy and beat him up, who would he go to reason?

No matter how much revenge he takes afterwards, this matter will definitely be widely circulated in his circle of friends......

So after feeling that Don Pudding might be mentally ill, he also started to make phone calls.

No, he has to shake people!

But he never imagined that in fact, Tang Pudding was also shaking people, and he couldn't imagine who Tang Pudding was shaking!
