Xueba's Sea of ​​Stars

Chapter 214 The Problem of the Century
Professor Liu Yubo recently has a trouble that makes him feel very hair loss, that is, he has recently found it difficult to even discuss with Wu Bin.

Although Wu Bin started to ask him about graphene, he didn't discuss with him in an educator's attitude, because Wu Bin's views on graphene were quite comprehensive at that time.

However, since Wu Bin began to study computational materials science, the questions raised became more and more complicated, which made him a little overwhelmed, and these questions also gave him a new way of thinking.

On this day, Liu Yubo was sitting in his office and looking at Wu Bin's new article "Simple Preparation of Ultra-low Voltage Transformer Loaded Graphene Fixed Electrode for Methanol Oxidation Reaction"

The paper describes the use of pulse current electrodeposition technology to prepare graphene-supported platinum nanoparticle electrodes for the electrooxidation of methanol in acidic media.

It can be said that electrodeposition technology has always been one of the important methods for preparing high-performance metal matrix composites based on low cost. It has attracted much attention because of the high hardness, excellent wear resistance and corrosion resistance of the coating.

After reading the whole thesis, Liu Yubo took a sip of strong tea and looked out the window. After a long time...he couldn't help but patted his forehead, "The kid still overtook me after all."

When Liu Yubo saw this thesis report, the summer vacation was over, and freshmen came to this brand new campus one after another.

At this time of year, some graduates will also return to HKUST, some to visit teachers, and some to see their good friends.

Most of these people are former members of the Student Union.

In the minds of most people, the student union is the most like a microcosm of society in the university. The members' way of getting along has always been the mainstream of friendship and interest, but this kind of friendship has the longest shelf life.

This year was the same, there were many people Li Yan didn't know in the student union, but the seniors of the student union were very excited when they saw them, and they seemed to have a very good relationship.

During the chat, these graduates will tell them some of their experience in graduate school, or some who have already worked will talk about the development direction of the market.

The current student union members will talk to them about the new things that happened on campus this year, including a freshman posting "science advances".

"Niuhide, I published a sub-journal in my freshman year, so I can't go to heaven if I go to graduate school?" Wang Gaofei, who was wearing a shirt, was surprised after hearing this.Because he was also from the academy before, he was a little excited when he heard that he had such a monstrous junior.

"And it's an independent work. I finished this paper completely by myself. When I first heard it, I felt my scalp tingling, like listening to a scripture." Zhou Fanrong, director of the external relations department, immediately added a sentence.

"Then I do have to go and read it."

"Li Yan, you should have that journal, right?" Zhou Fanrong turned around and asked Li Yan.

Li Yan nodded: "Well, it's in the dormitory, I can bring it here at noon."

"Then thank you first, you are that demon... oh no, Wu Bin's friend?" Wang Gaofei asked.

"Well, in the same dormitory."

"Hahaha, is it too stressful to share a dormitory with this kind of person?" Wang Gaofei asked with a smile.

"Fortunately, I can actually learn a lot from him." Li Yan replied with a smile.

"That's really a strange person. There used to be a god of learning in my dormitory, which put me under a lot of pressure. I always feel that this kind of person works so hard, and there is nothing for my hard work."

"Hahaha."

The people in the conference room burst into laughter.

At this time, Lu Ange from the Banlian Department suddenly took a picture of a person who was eating watermelon in the corner and said, "I remembered this evildoer, Brother Mao, your previous cheating program was changed by him, do you want to take a look?" ?”

"Oh? Does he know how to program?" Mao Rui was taken aback by being photographed, "Isn't he from the Academy of Fine Arts?"

"That's why I said he was a monster. It was a task given by Lao Cao to do this thing. We were wondering whether we should come to you for help. Li Yan said that he had a friend who could try it. This try is really good. It's done, a group of other institutes who are doing big experiments are sharpening their knives, once they find out that it is his updated software, they will definitely be hacked to death."

"It's interesting." After Mao Rui finished speaking, he quickly ate the remaining watermelon, wiped his hands, and ran to turn on the computer.

After seeing it, other people also gathered in front of the computer. You must know that Mao Rui was also the ace player of Xinyuan back then, otherwise he would not have been asked to design the program for catching cheats. What kind of evaluation will a senior give?

"Clap clap clap..."

With a burst of rhythmic keyboard tapping, Mao Rui quickly discovered Wu Bin's new design ideas from the running program.

"There is something. This kid models the similarity of programs as a maximum weight matching problem of a bipartite graph. Let each node u on the left side of the bipartite graph represent a function of P1, and the right side..."

"Brother Mao, can you tell me something we can understand?" Lu Ange patted Mao Rui's shoulder and asked with a heavy face.

"Roughly speaking, this network flow model approximates the edit distance of program instruction sequences. This model has a high degree of resistance to students adding some useless codes or deleting some printed debugging information when cheating, even for large functions. The splitting and merging of the code has very good results." After speaking, Mao Rui slapped the keyboard, "A master!"

Before anyone could answer, Mao Rui looked at Li Yan and asked, "Can I meet this person?"

"I can ask for you." Li Yan nodded.

"Just tell him that I want to make a fortune with him."

"Get rich?" Li Yan smiled, "He probably has no interest in getting rich, but if you want to discuss complicated procedural issues with him, I think he will be more willing."

"Hahaha, he's really a fucking master of science and technology, excellent, then you tell him that I have a century-old problem that a team of hundreds of people can't solve, and I want to discuss it with him."

"No problem." After Li Yan finished speaking, he took out his mobile phone and prepared to make a call.

At this time, Qin Simeng, who had been listening all the time, suddenly said, "That...Brother Mao, can I go together? I also want to improve my knowledge."

"Okay, come together, listening to this will really help you in the future."

It can be said that Mao Rui and Qin Simeng have known each other for a long time. They are both in the Faculty of Letters and the Student Union, so they are naturally very close.

"Then thank you Brother Mao." Qin Simeng said happily.

……

It doesn't matter to Wu Bin whether the school starts or not. At this time, he is working on his graphene in the laboratory, but when he was worrying about a strange data, the mobile phone in his trousers pocket suddenly vibrated.

He took it out and saw that it was Li Yan calling.

"What? The problem of the century? The restaurant, right? I'll be right there!"
