Xueba: I study hard in the wasteland world

After communicating with the instructor, Su Yu returned to school, but he no longer lives on campus. He bought a house in a newly developed high-end real estate next to NPU.

Su Yu, who lives alone, did not buy a villa or a large flat-floor mansion. Instead, she bought a 126-square-meter three-bedroom apartment. Compared with the empty mansion, Su Yu felt that living alone in a 126-square-meter three-bedroom apartment was very comfortable!

Su Yu went home with a pile of documents he had to fill out from school.

"so much!"

Sitting in the study room, Su Yu complained as she looked at the thick pile of documents she took out of her document bag.

These documents include information about his PhD graduation process, information about his employment as a professor at the School of Aeronautics and Astronautics and the School of Materials Science at NPU, information about his application for selection as an "Outstanding Youth", and information about his preparation for applying for "Academician". material.

And not only NPU, he also has the same backlog of materials in the Department of Physics of Yenching University and the Department of Mathematics of Shuimu University in Yenching.

But fortunately, the school has handled most of the information for Su Yu. Su Yu just takes a look at it and signs his name if there is no problem!

"Dingling~"

Su Yu was sitting in the study room filling out information. The door to his room rang. Su Yu was stunned. Not many people knew his address. Who was it? It was midnight!

Su Yu stood up and walked to the door. When she saw it, it was Zhang Tao. Su Yu was still very happy. She opened the door with a smile and asked, "Why are you here?"

"Brother, your high-profile Bentley Continental is all over the Internet. When I saw you coming to school, I guessed that you were here!"

Zhang Tao, wearing a black suit with his hands in his pockets, looked around Su Yu's house like an ascetic and overbearing CEO. Isn’t it too embarrassing for the world’s richest man? The world’s richest man lives here?”

Faced with Zhang Tao's disdain, Su Yu took a bottle of water from the refrigerator, handed it to him, and said, "Can I say that I am scared to live in a house that is too big for me? I always feel like I am upstairs and downstairs. , there are people or things in those rooms that I can’t see~”

"Hahaha!" Hearing this, Zhang Tao laughed so hard. He wanted to say that you are so awesome, but you are also afraid, but he still held it back, smiled and put his arms around Su Yu's shoulders, and said: " Let’s go, come to Xijing, let’s go out and have some fun!”

"Where to go?" Su Yu asked. He really didn't want to go out now, especially not to a public place where he would be recognized!

"Let's go, don't be so bored. We are already rich, so we should experience the life of rich people!" Zhang Tao said with a smile.

"Then after I get out, you are not allowed to introduce me to anyone!" Su Yu said.

"No problem!" Zhang Tao nodded!

After getting on Zhang Tao's supercar, Su Yu followed Zhang Tao to experience the nightlife of Xijing City!

Of course, following the supercar, there were two Land Rover SUVs full of security guards. Some time ago, Zhang Tao, the "third richest man in China", almost had an "accident". Since then, he has started hiring bodyguards!

Zhang Tao took Su Yu to a high-end young dinner party. As soon as Zhang Tao arrived, he was taken away without saying a word.

Su Yu, who was wearing a peaked cap, was not recognized at first. He just sat in the corner, like an ordinary college student attending a high-end party with the "second generation". No one cared about him, and no one came to talk to him!

During the grand dinner, Su Yu felt a little embarrassed when she was alone.

"Damn Zhang Tao, I will never go out with him again!" Su Yu cursed in her heart, and then started to inspect the lively dinner scene.

"Sorry, sorry!"

After getting rid of everyone's flattery, Zhang Tao hurried back to Su Yu and apologized to Su Yu.

Seeing Su Yu's thoughtful look, Zhang Tao asked Su Yu curiously: "What are you thinking about?"

Su Yu shrugged, took a sip of the wine in the glass, and said, "At first, I was blaming you for leaving me behind!"

Zhang Tao explained helplessly: "I didn't leave you behind, you also saw that I was dragged along forcefully! And you didn't let me introduce you to everyone, and besides, didn't I come back immediately? "

Su Yu was not angry. He said, "So I'm not angry either, and it's quite interesting."

Su Yu became interested, sat upright, and then asked Zhang Tao seriously: "Zhang Tao, do you know about the NP-complete problem?"

"I know! One of the seven most difficult mathematical problems in the world!"

Zhang Tao just nodded and finished speaking, then his eyes widened in an instant, staring at Su Yu and saying in shock: "Brother, you have already proved an NS equation, you don't want to solve another seven major mathematical problems in the world, do you?"

Su Yu shrugged and said to Zhang Tao: "It's not that easy, I just remembered it!"

What is an "NP-complete problem"?

Let’s take the dinner party Su Yu attended today as an example:

Tonight, Su Yu was taken to a high-end and grand young people's dinner by Zhang Tao. However, Zhang Tao left and left Su Yu alone. Su Yu would inevitably feel awkward and uneasy.

Su Yu felt awkward and wanted to know if there was anyone he already knew at this banquet.

This is, if someone says to Su Yu: You must know that so-and-so who is drinking.

It didn't take a second for Su Yu to scan there and find that what this person said was correct. Su Yu knew that so-and-so!

However, if there is no such hint, Su Yu has to look around the entire hall and examine everyone one by one to see if there is anyone he knows.

Generating a solution to a problem usually takes much more time than verifying a given solution.

Simply put, this is an np-complete problem!

This is also the problem that Su Yu was thinking about just now. As for solving it, Su Yu really has no idea for the time being.

"I gotta go!"

Su Yu picked up her coat and planned to leave.

Although Zhang Tao originally wanted to have fun here, Su Yu is leaving and Zhang Tao doesn't plan to stay any longer. Today's party made Su Yu unhappy, and Zhang Tao doesn't plan to attend such parties in the future.

Zhang Tao waved to the two security guards who had been standing behind Su Yu and motioned to leave!

Holding Su Yu's shoulders, Zhang Tao smiled and said: "Yu, from now on I will be like you, keep a low profile, so that no one will recognize me when I come out, and then I can show off and slap you in the face!"

"When I tell them tomorrow that the person they snubbed is the director of ****, the world's richest man, and the founder of the fruit candy company, they will definitely regret it to death!"

Picking up his coat and taking a look at the lively group of "second generations", Zhang Tao said: "You don't even need to say anything. If the news spreads that you were left out tonight, there are many second generations here, and together they will Their parents will all be implicated!”

There is nothing wrong with what Zhang Tao said. Su Yu's influence is already great!

Take the business field as an example: "I heard that his son neglected Su Yu, the big boss of the fruit candy company. If I do business with his family, will the fruit candy company be angry when they find out? Forget it, it's so important anyway. He has many business partners, but I still won’t do business with him!”

Thinking of this, Zhang Tao sighed to Su Yu: "Su Yu, you are really awesome!"

"That's right!" Su Yu nodded proudly!

Su Yu didn't understand what Zhang Tao was talking about. He didn't even know anyone at the dinner. He thought Zhang Tao was praising him for attending the dinner, so he could think of the "NP-complete problem"!
