Chapter 208: The Problem of the Century (Page 1/1)

Professor Liu Yubo recently had something that made him feel very hair-loss, that is, he actually felt that it was a little difficult to even discuss with Wu Bin recently.

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

However, since Wu Bin began to study computational materials science, the problems thrown up have become more and more complicated, which has made him a little overwhelmed, and these problems have also given him new ideas.

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

Graphene-supported platinum nanoparticle electrodes were prepared by pulsed current electrodeposition and used for the electrooxidation of methanol in acidic media.

Electrodeposition technology has always been one of the important methods for the preparation of high-performance metal matrix composites based on low cost.

The coating has attracted much attention because of its high hardness, excellent wear resistance, and corrosion resistance.

After reading the whole paper, Liu Yubo took a sip of strong tea and looked out the window, and ...... for a long time He couldn't help but pat his head, "That kid still overtook me after all." ”

When Liu Yubo saw this thesis report, the summer vacation had ended, and the freshmen had already come to this brand new campus one after another.

At this time of year, some of the graduating seniors also return to HKUST, some to visit their teachers, and some to see their younger brothers and sisters with whom they have a good relationship.

Among them, the most are the seniors of the student union, the most like the microcosm of society in the university, the way the student union gets along has always been between love and interests, but this kind of friendship has always been the longest shelf life.

This year is the same, there are many people in the student union that Li Yan doesn't know, but the seniors are very enthusiastic when they see them, and they seem to have a very good relationship.

During the chat, these graduating seniors will tell them some of their experiences in graduate school, or some of them will talk about the direction of market development after some have already worked.

Current student council members talk to them about what's happening on campus this year, including a freshman who posted Science Advances.

"Cowhide, I published a sub-journal in my freshman year, and I can't go to heaven for graduate school?" Wang Gaofei, who was wearing a shirt, was surprised after hearing this. Because he used to be from the Academy, he was a little excited when he heard that he had such a demon junior.

"And it's an independent work, I got this paper completely by myself, and when I first listened to it, I felt my scalp tingle, like listening to a book from heaven." Zhou Fanrong, director of the External Relations Department, immediately took a sentence.

"Then I do have to read it."

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

Li Yan nodded: "Well, in the dormitory, I brought it over at noon." ”

"Then thank you in advance, you're the demon...... Oh no, Wu Bin's friend? Wang Gaofei asked.

"Well, in the same dormitory."

"Hahaha, isn't it particularly stressful to share a bedroom 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, I used to have a god of learning in my dormitory, and I was so stressed that I couldn't do it, I always felt that this kind of person worked so hard, and I still have a hair for my efforts."

"Hahaha."

There was a burst of laughter from the people in the conference room.

At this time, Lu Ange from the class union department suddenly patted the next person who was eating watermelon in the corner and said; "I remembered when I mentioned this demon, Brother Mao, his previous procedure for catching cheating was changed by him, do you want to take a look?"

"Oh? Will he still do the program? Mao Rui, who was patted, was stunned for a moment, "Isn't he from the Academy?" ”

"That's why he said that he was a demon, at that time, the task given by the teacher, we were worried about whether we should come to you for help, Li Yan said that he had a friend who could try it, this trial, it was really done, a group of other courtyards were sharpening their knives for big experiments, once they knew that it was the software he updated, they would definitely be hacked to death."

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

After hearing this, the others also rushed to the computer, you must know that this Mao Rui was also the ace player of the Academy of Letters, otherwise he would not have been allowed to do this cheating program, and now that he has pushed forward the waves, they are quite curious about what this senior will give him.

"Bang Bang Bang ......"

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

"Something, this kid modeled the similarity of the program into a maximum-weight matching problem for a dichotomous graph, so that each node u on the left side of the bipartite graph represents a function of P1, and the right side ......"

"Brother Mao, can you say something that we understand?" Lu Ange patted Mao Rui's shoulder and asked.

"Roughly speaking, this network flow model approximates the editing distance of the program instruction sequence, and this model has a high degree of resistance to students adding some useless code or deleting some printed debugging information when cheating, and even has a very good effect on splitting and merging large function code." After speaking, Mao Rui slapped the keyboard, "Master!" ”

Then, before anyone else answered, Mao Rui looked at Li Yan and asked, "Can you let me meet this person?" ”

"Russia...... Let me ask for you. ”

"You just tell him I want to get rich with him."

"Rich?" Li Yan smiled, "He probably has no interest in making a fortune, if you want to discuss procedural issues with him, I guess he will be more willing." ”

"Hahaha, I'm really a science and technology person, excellent, then you can tell him that I have a big problem of the century that can't be solved by a team of hundreds of people and want to discuss with him."

"There's nothing wrong with it." After Li Yan finished speaking, he took out his mobile phone and prepared to call.

At this time, Qin Simeng, who had been listening, suddenly spoke: "That ...... Can I go along? I also want to increase my knowledge. ”

"Okay, let's come along, listening to this will really help you in the future."

Mao Rui and Qin Simeng can be said to have known each other for a long time, the two of them are in the same letter academy, and they are both in the student union, so they are naturally very familiar.

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

……

Whether school starts or not, it has no impact on Wu Bin, who is tinkering with his graphene in the laboratory every day, but just as he is worried about a strange data, the mobile phone in his pants pocket suddenly vibrates.

When I took it out, it was Li Yan who called.

"Huh? The problem of the century? Well, see you at the restaurant! ”
