I really don't want to skip a grade

Chapter 292 Start to repair Du Chen's dissatisfaction
Next, during the Monday of this week in the real space, the four of Xiao Dong stayed in the sage space for more than two months!
During these two months, when others came to attack them, they resisted and counterattacked. When others did not attack them, the four of them did their own things.

Chen Xuejun and Du Chen are concentrating on improving the micro-drones and the monitoring equipment around the villa. At present, they have developed a controller that can control four micro-drones at the same time. The monitoring equipment around the villa can monitor 800 meters around the villa. meter range, and will automatically select dangerous targets to issue an alarm. These two major improvements have greatly enhanced their defensive and offensive capabilities!

Li Yishu is mainly responsible for the security tasks. By the way, she put forward her idea of ​​strengthening the defense of the villa to "three-dimensional". Improving the monitoring equipment of the villa is her suggestion. Build a simple network of tunnels within 300 meters so that you can attack the enemy by surprise when there is an enemy coming.

Of course, whether it is to improve the micro-drones and villa monitoring equipment, or to implement the "authentic" defensive counterattack strategy, a large amount of system currency is required. However, after they fought a few beautiful defensive counterattacks, especially finally captured And after selling the villa diagonally opposite, they harvested a large amount of system currency, which was enough for them to complete these two tasks. At the same time, they also rebuilt and strengthened their villa (it should be Xiaodong's villa to be precise).

When others were not attacking them, Xiao Dong spent half of his time "researching" and sneak attacking others. Due to his brilliant record, his points had already approached the [-] mark twice, and he was about to be promoted to Glory Gold. He was almost killed each time, and both times his points and system coins were cut in half!
Hey, they are improving, others are improving, their marksmanship and defense are improving, others' defense and marksmanship are also improving, many host houses and villas have also been modified and upgraded by themselves, it is more and more difficult to sneak attack It's difficult.

Xiao Dong then put his flag down, seeing that his points had stopped at the point of 60499/100000, he didn't want to take the risk of attacking others anymore.

Now, besides the 5000 system coins handed over to Li Yishu (excluding the [-] system coins lent to him by Chen Xuejun), he also has more than [-] system coins in his hand, plus the transaction Under the management of Li Yishu's AI assistant, the system coins given to Li Yishu have been making money from money. It is estimated that in the foreseeable future, it will be enough for him to spend on weapons and ammunition for counterattacks, so he stopped , and began to prepare to concentrate on studying knowledge and medical skills in the villa.

But what makes Xiao Dong feel a little depressed is that this guy Du Chen has more and more opinions on him now. Although he didn't say it clearly, everyone can see his eyebrows.

This opinion was vague before, but since that night when Du Chen saw rockets fired in from the second floor of the villa, and Li Yishu was held down by Xiao Dong for protection, Du Chen's opinion on Xiao Dong It became more and more obvious. In the middle of the night, Li Yishu was not in her bedroom, but was with Xiao Dong on the second floor?
This shows what?
Xiao Dong, you already have a girlfriend, is it really good to eat more and occupy more like this?

But recently, everyone can see that Li Yishu is getting more and more clingy to Xiao Dong, Xiao Dong will go out and attack her, she will be uneasy, and when Xiao Dong comes back, she almost always sits quietly beside Xiao Dong, At night, when it was Xiao Dong's turn to be on duty on the second floor of the villa, Li Yishu would always go to the second floor to sleep, and when it was Li Yishu's turn to be on duty at night, Xiao Dong naturally had to go to the second floor to accompany her.

This is really like a pair of intimate lovers, only the two of them have to prove their relationship with their own mouths!
(As for whether the two of them have taken the most substantial step beyond the boundaries of their classmates, only God knows!)
For this problem, Xiao Dong couldn't excuse himself from Du Chen.

Du Chen is a very orthodox guy, and the key point is that this guy also likes Li Yishu, which made him hate Xiao Dong in a double way, not only hating Xiao Dong's playing with girls' feelings, but also including his own love rivals. layer hate.

So, how does Xiao Dong excuse himself from Du Chen?

Because he himself has indeed fallen in love with Li Yishu now, and his own behavior is indeed very immoral!

He can tell Du Chen, I f*ckingly work so hard, including studying mathematics and physics that I don't like very much, just to have the potential qualification to eat more and occupy more.

Saying this is... emmm, it's too shameless...

Numerous things in the world have proved an irrefutable truth, too many things can only be done and cannot be said!

The author is not guilty, or it is only a minor crime, but the speaker must be a major crime!

So Xiao Dong can only do it, not talk about it.

So Xiao Dong is doomed not to be able to excuse himself from Du Chen!
There is only one way for him, to defeat Du Chen in the place he is most proud of, and make him docile, so that he can subconsciously admit that a super strong like Xiao Dong is qualified to own several Little Apple's!
So what is Du Chen most proud of?
Math of course!
So far, Du Chen has not only won the International Mathematical Olympiad Gold Medal, but has also published two SCI papers (including the one he collaborated with Xiao Dong)!He has become the recognized mathematics king among freshmen in Huaqing!

Tong Bo Academy also specially rewarded him in this regard!
Therefore, if he can defeat Du Chen in mathematics, a straightforward and stubborn boy like Du Chen will definitely subconsciously admire him Xiao Dong, and subconsciously admit his strength to Xiao Dong, To admit that Xiao Dong enjoys the right to own two or three little apples!

Xiao Dong is convinced of this.

But what he doesn't believe deeply is whether he can beat Du Chen in mathematics?

(He refers to defeating Du Chen in the true sense, not defeating Du Chen by relying on the kind of opportunistic method that can detect the opponent's thinking with a magnetic field.)
There are only three things he is better than Du Chen now, one is that he can directly "steal" their thoughts and memories, even including some logical thinking, from top masters like Yang Lao; the other is that his mental power is particularly strong , now the mental power of 4.0 completely crushes Du Chen's mental power of 3.4, and can even crush Chen Xuejun's mental power of 3.6!The third is that as long as he is not afraid that his brain will not fit, he can copy mathematics knowledge without limit!

But the most terrible thing is that he lacks Du Chen's fanatical enthusiasm and interest in mathematics, and he also lacks the profound knowledge of mathematics built up from a young age like Du Chen. , so it lacks Du Chen's unique spirituality for mathematics!
Therefore, in order to defeat Du Chen, Xiao Dong must first force himself to become interested in mathematics!
But like so many people have said, I can do everything, but I just can't solve math problems!
It is really difficult to make a person interested in mathematics that challenges the limits of one's thinking!

But, fortunately, doesn't mathematics have an important way of thinking that is to transform thinking?
Well, thinking about math problems is boring and painful, but the results that can be pretended to be after solving math problems are pleasing to the eye?

Xiao Dong doesn't pay much attention to winning the mathematics award, but after winning the mathematics award, he can let the world admit that he has the special qualification of a few little apples (of course it is potential, 90.00% of the world's problems are Hiding under the deep water) but Xiao Dong valued it very much?

So, thinking about it this way, Xiao Dong really got interested in studying mathematics again!

During these two months of sage time, half of the time Xiao Dong was biting the bullet and delved into mathematics. He has also gone through all the branches of mathematics (of course, many of them are just scratching the surface like concepts) I have understood it for a while), and I feel that there will not be much gain if I go through it again. Learning is mainly based on solving problems, with the need for continuous in-depth research, rather than relying on in-depth research for the purpose of pure learning. .

Therefore, with this in mind, Xiao Dong first went to understand the seven major mathematical problems in the world today.

But after he understood these problems, his entire forehead wrinkled into a dry apricot!

For example, one of the seemingly best-understood questions: NP=P?

This is a problem born of the field of theoretical computing.

In mathematical theory, since all completely polynomial non-deterministic problems can be converted into a type of logical operation problems called satisfaction problems.So, is there a deterministic algorithm for this kind of problem that can directly calculate or search for the correct answer in polynomial time?
It is difficult to explain in human terms. For example, you can quickly calculate the shortest and optimal route for a courier to deliver goods to two or three places, but when the number of delivery points increases, the calculation amount of the shortest and optimal route will decrease. Presents an increase in geometric progression!
For example, if a courier delivers goods to 19 locations, you need to calculate the shortest and optimal delivery route according to the most common permutation and combination algorithm. According to the current computer capabilities, you need to calculate for 3000 years to calculate!
So, for such problems, can we find a simpler algorithm that allows the computer to quickly calculate the result?

That is to say, can you find the common points among n P problems, establish an algorithm, and then convert these n P problems into one P problem, and then let the computer quickly calculate the definite result?
Can it?still can not? !

Is this the famous NP=P?conjecture! ! !

If you can prove NP=P, then you will not only get a reward of 100 million US dollars (this is not the dream of mathematicians), but your contribution to all mankind will be great!
For example, the folding of human protein is such a problem that presents a geometric progression. If you can prove that NP=P, then it is just around the corner for humans to unravel the mystery of protein folding!Many intractable diseases of the human body, such as cancer, are expected to be solved. Is the temptation big enough? !

If you can solve this problem, then, if you have two, three, four, five little apples, who will object?
Assuming that Xiao Dong unlocked it, then Du Chen could only look at him and sigh!

But the question is, like NP=P?This question is too broad, too general, too grand, too vague!

Such a vague and vague question, do you want to give it a precise mathematical modeling and establish a definite mathematical algorithm?

Are you crazy or am I crazy?
So Xiao Dong hurriedly shook his head and passed it!
He doesn't want to be crazy, so he doesn't want to touch such a crazy question!

But the problem is that the other six math puzzles are also such "empty and vague" problems, and none of them are easy to solve!
Oh, there seems to be a slightly easier solution, that is, the Poincaré conjecture - a proposition with basic meaning in topology - seems to be more specific, but it has been proposed by the Russian mathematician Grigory Pere Perelman proved it around 2003 (in 2006, the mathematical community finally confirmed that Perelman's proof solved the Poincaré conjecture).

Of course, Xiao Dong seriously suspects that he thinks it is easy to solve it because Perelman has solved it. This should be a common thought of human pink eye disease.

However, Perelman was able to solve one of the seven mathematical problems, which also gave Xiao Dong confidence. Since someone can solve one, it means that the human brain can still solve such "empty and confusing" problems?
His current mental power is 4.0, and it is still in the process of rising. Even if it is not possible to solve a complete one for the time being, he can disassemble a certain one to solve part of it?
For example, that NP=P?Can he solve a problem similar to human protein folding first?Or think that this involves a biophysical problem, which is too grand, can you first solve the algorithm problem of an optimal route for a courier to deliver a courier?

Thinking about it this way, Xiao Dong's forehead wrinkled into dry apricots finally slowly stretched out again. I have a mental strength of 4.0. There is no reason why I can't solve a bigger math problem!
