The villain he just wants to learn [Transmigration Book]

When the school bell rang at noon, Zhou Ruisen was the first to stand up.

"Brother Can, shall we eat in the cafeteria or go outside?"

Ji Can thought there were too many people, so he shook his head: "Go first, I'll go later."

Li Nuo was already about to leave, but upon hearing this, he sat down again and said, "Then I'll go later."

"Isn't it?" Zhou Ruisen was anxious, "Aren't you even active in eating?"

After all, for a scumbag, the only comfort this school gives him is the nearby gourmet restaurant!

Li Nuo opened the exercise book and ignored him: "I'm going to you, I still have homework to finish."

Looking at the snow-white exercise book, Zhou Ruisen: "..."

Where did you not finish writing?You fucking didn't write it at all!

Zhou Ruisen had to start a game to continue his life.

Forget it, the food is precious, and the price of Cange is even higher.

When the minute hand passed 12:30, Ji Can finally stood up: "Let's go."

"I'm going crazy from hunger." Zhou Ruisen tapped surrender in the game without hesitation.

Li Nuo also threw down the exercise book that both hated each other.

Outside the classroom, Gu Jiangheng had just returned from lunch, when he met a boy who had just reached his chin at the door, raised his doggy eyes and asked, "Excuse me, is Ji Can in this class?"

"He's in the last row."

Before Ji Can walked out of the classroom, he ran into Tao Lang who came in with a food box.

The other party put the things on his table and smiled: "This is the lunch Mom prepared for you."

Tao Lang sent it to Ji Can after eating on purpose.

I just hope that Ji Can eats the unpalatable cafeteria, only to find a large table of delicious food when he comes back, but his stomach is filled with garbage from the cafeteria, and he can't eat any more.

I can only watch helplessly, or grit my teeth and hold on.

But he didn't want Ji Can to immediately take the food box and put it on the table, and ate with two classmates around the food box with relish.

Tao Lang: "..."

How is this different from what he imagined?

Looking at Tao Lang who was staring at the food box intently, Ji Can asked, "Do you want to go together?"

"..."

"No, I've already eaten." Tao Lang ate, and left without even bothering to pretend.

Knowing that Ji Can's relationship with his family is not good, Zhou Ruisen complained while eating: "Your brother is annoying enough, he only brought you food at this time, if we didn't go to do our homework late, we would have missed it long ago. "

Ji Can is propping up his mobile phone with a book, and is concentrating on watching "SpongeBob SquarePants".

The first class in the afternoon was Chinese class. The best time for sleeping was combined with the best time for sleeping, and a large area of ​​the classroom fell asleep.

"Thomas Huxley said that known things are finite, and unknown things are infinite... Today we study an expository essay, "The Frontiers of the Universe"..."

Li Feiyong read the contents of the courseware slowly, which made people fall asleep even more.

When everyone was slacking off, Ji Can, who was in the last row doing homework seriously, stood out instead.

His back is straight, his eyes are focused, and he is not in the mental state he should be in Chinese class.

Li Feiyong frowned, and raised his voice: "Ji Can, you are here to answer this question."

Ji Can had been immersed in the derivation process for a long time, but he didn't respond to Li Feiyong's calling twice. It wasn't until the study committee member in the front seat knocked on his desk that he came back to his senses and raised his head in confusion.

"What are you knocking on my desk for?"

He Jinfeng: "..."

Fortunately, he still wants to sell his favor.

Ji Can scratched his head, lowered his head and continued to write the formula.

This made Li Fei courageous enough. He strode down from the podium, pulled off Ji Can's calculation paper, and said sharply, "Ji Can, stand up, what are you doing?!"

Ji Can was forced to stop calculating, frowned and said, "NP is completely problematic."

np? ? !

No matter how sleepy the students were, they were awakened by these two words, and burst into laughter instantly.

Li Feiyong's face turned red and white, and he said with a straight face, "What are you pretending to be in your head all day long? And n... n... can this kind of thing be said in class?"

Ji Can wondered: "Is there anything you can't say?"

The students laughed even louder.

"The np complete problem," Gu Jiangheng was awakened by the laughter of his classmates, explained slowly, "It is a non-deterministic problem of polynomial complexity. Simply put, it is to verify whether p is equal to np."

Li Feiyong: "???"

WTF?

Ji Can said to Gu Jiangheng: "You speak too academically, the teacher can't understand."

Li Feiyong: "..."

He really didn't understand.

Both his undergraduate and graduate studies were in the Chinese Department. He hasn't studied mathematics for 800 years, and he can't even solve linear equations in two variables. How can such complicated mathematical theorems be possible?

Ji Can is quite "considerate". Seeing his bewildered face, Ji Can immediately explained: "p stands for relatively simple problems, and np stands for very difficult problems. For example, we can easily know that the product of the prime number 9929 times the prime number 9931. But if Let me tell you, 98,604,899 can be factored into two prime numbers, and your checking process will be much more difficult."

Li Feiyong: "..."

The whole class: ⊙_⊙

Sir, what are you talking about?

Seeing everyone's blank faces, Ji Can had no choice but to continue to explain: "For example, when the school holds a parent-teacher meeting, if the grade director tells you that the lady sitting in the second row is your first love, you will definitely find out immediately. she."

"But if no one tells you, you have to look at each face, maybe you need to see the last person before you find out that your first love came to school to help your child hold a parent-teacher meeting."

Li Feiyong: "..."

Ji Can: "So, we want to know if there is a definite algorithm that allows us to see 98,604,899 and know that it is the product of the prime numbers 9929 and 9931, or let you enter the classroom and look up You can find your first love among your parents."

"I hope to use a simple method to solve a complex problem. What we are going to do now is this kind of thing." Ji Can concluded.

After a long silence, Li Feiyong pointed to the back door and said coldly, "Get out."

Ji Can: "If it succeeds, then we have found a shortcut to this world."

Li Feiyong: "Get out!"

Ji Can: "..."

Standing as a penalty is commonplace, Ji Can obediently stood up and walked out.When I walked to the door, I remembered that I forgot to bring the draft paper, and went back to grab the previous calculation paper and walked out.

Li Feiyong: "..."

This is not like standing for punishment, he couldn't wait to see Ji Can!Next time he has to make Ji Can recite the full text of "Li Sao"!

A good Chinese class turned into Ji Can's personal talk show.

Li Feiyong sighed and continued his lecture: "Next, please turn to page 119..."

As soon as the voice fell, a tall man in the last row stood up again.

Li Feiyong looked up, and almost died of anger.

"Gu Jiangheng, what are you doing?"

"Punishment."

"What are you punishing for standing? Sit there and listen to the class for me!"

"I just fell asleep, and I was automatically punished to stand."

Gu Jiangheng dropped these words, put his hands in his trouser pockets, and walked out swaggeringly.

There was an instant burst of cheers in the classroom.

"The school grass is awesome."

"This forced me to obey."

"Handsome is still Gu Shenshuai!"

Li Feiyong: "..."

He doesn't want to teach this class anymore, whoever wants to teach can come.

When Gu Jiangheng came out, he saw Ji Can lying on the balcony writing his latest formula.

The boy is tall and straight, with a stretched neck, like a thriving green pine.

Because he had just dyed his hair, Ji Can's hair was abnormally black, but it made the back of his neck even fairer.The golden sunlight fell on the soft skin, and the almost transparent white fluff could be seen.

It seems that being punished to stand on the balcony has no effect on him, as long as he is given a pen, he can enter his own world anytime and anywhere.

This is the appearance of Ji Can in his dream that he has never had before.

Gu Jiangheng checked Ji Can's background, and he was indeed admitted to the No. [-] Middle School by virtue of his ability. The reason why he is now at the bottom of his age is that his grades dropped sharply in his first year of high school.

That year, his parents divorced, his mother went overseas, and his father quickly found him a stepmother, who was also a colleague of the company and became a full-time employee, and brought a younger brother who was a top student to live in Ji's house.

Is he really unwilling to study because of family reasons?

But what made him suddenly decide to study hard?

At the beginning of September, the afternoon sun shines through the sycamore trees, casting waves of dappled light and shadows on Jican's draft paper.

A gust of wind blew the draft paper that Ji Can piled up next to him everywhere.He frantically turned around to pick up something, but unexpectedly crashed into a broad chest.

Ji Can raised his head and saw Gu Jiangheng's beautifully curved Adam's apple and high nose bridge.The boy looked at him with narrowed peach blossom eyes, holding the draft paper that he flew away in his hand.

Ji Can froze for a moment, took a step back, and said thank you.

Gu Jiangheng stuffed the draft paper into his arms, and took a step forward: "Where have you come?"

Ji Can came back to his senses and explained: "I mainly use the hypothesis method, assuming p=np first, and then prove it. But I encountered a problem in the proof process..."

After listening to Ji Can's question, Gu Jiangheng thought for a while and suggested: "You can use a quantum computer to perform calculations, but it may not be successful. People used quantum mechanics and other methods to perform calculations long before you, but unfortunately they couldn't find it. Answer."

Ji Can heard what he meant: "You counted too?"

Gu Jiangheng nodded.

Ji Can: "Then did you succeed?"

After a long silence, Gu Jiangheng slowly shook his head: "No."

He tried, but he didn't find a shortcut to this world.

However, one of his previous algorithm models was purchased by a food delivery company, and they applied the model to the courier's catering route, which can be regarded as the primary application of this problem.

"Actually, I don't believe that p=np." Ji Can stopped writing and looked at Gu Jiangheng, his brown pupils filled with seriousness, "I just want to know why p is not equal to np."

Gu Jiangheng didn't speak, just looked at him silently.

When he thought the world could only be like this, the person in front of him brought him a pleasant surprise.

Ji Can felt a little uncomfortable being stared at by him, touched his nose and lowered his head to continue computing.

The next moment, there was a sound of footsteps at the top of the stairs, and a strange middle-aged male voice came over.

"Little classmate, are you studying this?"

Ji Can turned around and saw a group of middle-aged men in suits and leather shoes.

The one who walked in the front had the party emblem pinned to his chest, and one step away behind him stood the principal of No. [-] Middle School and the group leader of the second grade.

In the afternoon of the same day, a post appeared on the No. [-] Middle School forum, spreading the scariest rumor since the school was founded.

【shock!The school grass and the school bully were fined to stand in class! 】

【shock!The school grass and the school bully continue to engage in np in the corridor! 】

【shock!The school grass and the school bully were doing NPC in the corridor, but they were smashed by the principal and the leaders of the Education Bureau! 】

People who eat melons: Surprised, there are no more posts! ! !
