Chapter 214 The Problem of the Century

Professor Liu Yubo has a problem that makes him feel like losing his hair recently, that is, he has recently started to find it difficult to even discuss with Wu Bin.

Although Wu Bin began to ask him about graphene, he did not discuss it with him in an educator's manner, because at that time Wu Bin's views on graphene were already quite comprehensive.

But since Wu Bin started studying computational materials science, the questions he was asked became more and more complex, which made him overwhelmed. Moreover, these questions also gave him new ideas.

On this day, Liu Yubo was sitting in his office reading a new article written by Wu Bin, "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 and use them for the electrooxidation reaction 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 composite materials based on low cost. Because of the high hardness, excellent wear resistance and corrosion resistance of the coating, it has attracted much attention.

After reading the entire paper, 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, "That kid still got ahead of 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 graduating seniors will also return to HKUST, some to visit teachers, and some to see juniors with whom they have good relationships.

The largest number of these people are former members of the student union.

In the minds of most people, the student union is the most microcosm of society in the university. The way members get along has always been based on friendship and interests. However, this kind of friendship has the longest shelf life.

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

When chatting, these graduated seniors will tell them some of their experiences in graduate school, or some who are already working will talk about the development direction of the market.

The current student union members will tell them about the new things happening on campus this year, including the incident of a freshman posting "Science Advances".

"Nice, you published a sub-journal in your freshman year, so why don't you go to graduate school?" Wang Gaofei, who was wearing a shirt, said in surprise after hearing this. Because he was also from the Physical Academy before, he was a little excited when he heard that he had such a monster junior.

"And it is an independent work. I completed this paper completely by myself. When I first listened to it, my scalp felt numb, as if I was listening to a book from heaven." Zhou Fanrong, director of the External Relations Department, immediately added.

"Then I really 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 over at noon."

"Then thank you in advance. Are you that demon... oh no, Wu Bin's friend?" Wang Gaofei asked.

"Yes, in the same dormitory."

"Hahaha, is it very stressful to be in the same dormitory with such a 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. I used to have a god of study in my dormitory. He made me extremely stressed. I always felt that even though such people worked so hard, my efforts were of no use."

"Hahaha."

People in the conference room burst into laughter.

At this time, Lu Ange from the class liaison department suddenly took a picture of a person eating watermelon in the corner and said, "I remembered this monster. Brother Mao, your previous program for catching cheaters was changed by him. Do you want to take a look?" ?”

"Oh? He can also do programming?" Mao Rui was stunned for a moment after being patted, "Isn't he from the Institute of Physics?"

"That's why I said he's a monster. This thing was a task given by Lao Cao before. We were wondering whether we should come to you for help. Li Yan said he had a friend who could give it a try. This time, it really worked. It’s done, a group of people doing big things experiments in another hospital are sharpening their knives. Once they find out that it’s the software he updated, they will definitely hack them to death.”

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

After seeing this, other people also gathered in front of the computer. You must know that Mao Rui was also the ace player of the Academy, otherwise he would not be allowed to design this program to catch cheaters. Now that the waves are pushing ahead, they are really curious about this. What kind of evaluation would a senior teacher give?

"Pah, pah, pah..."

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

"There is something. This guy modeled the similarity of the program into 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 us something we can understand?" Lu Ange patted Mao Rui on the shoulder and asked with a heavy expression.

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

Then, before anyone else 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 complex procedural issues with him, he will probably be more willing."

"Hahaha, you are really a damn guy from HKUST. He is excellent. Then tell him that I have a big problem of the century that cannot be solved by a team of hundreds of people. I want to discuss it with him."

"Nothing wrong." After Li Yan said this, he took out his mobile phone and prepared to make a call.

At this time, Qin Simeng, who had been listening, suddenly said: "Well...Brother Mao, can I come with you? I also want to increase 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 were in the same college and were in the student union, so they were naturally familiar with each other.

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

…

Whether school starts or not has no impact on Wu Bin. At this time, he was tinkering with his graphene in the laboratory, and just when he was worried about a strange data, the phone in his pants pocket suddenly vibrated.

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

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