Chapter 233: Old Mei is really happy, OJ ranking (4k)

"Here is the list of the top 50 students in the ACM Club OJ rankings from freshman to junior year at the School of Information Science and Technology. The basic information is all here. You can pick one."

Mei Hong smiled warmly, holding a stack of documents and looking at Xu Qingshan.

"I want to bring my girlfriend along."

Xu Qingshan gave Mei Hong a heads-up in advance.

"I know, I know. Lao Chen has already said that there is still one spot available."

Mei Hong continued to smile.

How could Old Mei not be happy?
Xu Qingshan!

What a convenient little thing to use. You can just plug it in wherever you need it. It’s fully automatic and you don’t have to worry about it.

Look at the people in the School of Mathematics, they are already making a lot of money.

It is said that the "Annals of Mathematics" has replied to the acceptance letter. Except for the school leaders mentioning it during the freshman ceremony, there has been no movement recently. It's not that those bastards in the School of Mathematics are keeping a low profile, but that they are planning something big.

They at the Academy of Information Science and Technology are also jealous!
Especially Lao Mei, he was the one who went to Heilongjiang personally to snatch the person.

Although Xu Qingshan also participated in ICML and published his paper at the conference, although that work was in the field of machine learning, it was still regarded as a mathematical achievement.

The main reason was that Chen Dayue was too cunning at the time and completed the results reporting procedures in advance.

By the time Mei Hong found out that Xu Qingshan had gone to Canada, all the procedures had been completed.

This year, the School of Mathematics has achieved at least one-fifth of the high-end academic indicators of each college, thanks to Xu Qingshan. That means that the Annals of Mathematics and ICML can produce many more articles!
Fortunately, if Xu Qingshan is willing to participate in ICPC this time, their Institute of Information Science and Technology will also be able to get some benefits.

Even if you win a gold medal in ICPC, it is completely incomparable to an article in the Annals of Mathematics.

But if he could break the long-standing performance bottleneck of Kyoto University, he would be proud of it as the dean.

As for whether Xu Qingshan has that ability?

This was totally out of Mei Hong's consideration.

"Oh? What's the situation with this poplar tree?"

Xu Qingshan pointed at a boy who was at the front of the list but whose name was circled with a question mark.

He felt that this person looked very familiar, and after thinking about it, he realized that he had seen him in a technology newspaper in his previous life. He was a well-known KOL in the technology and gaming circles. He joined the "Huawei Genius Youth Program" as soon as he graduated from graduate school and was engaged in research related to AI algorithms and AI chips.

He is also good at circuit design, structural design, software and algorithm development, and hand-made cyber robots, with excellent theory and practice.

If we were to say what this person's biggest shortcoming is, it would be that he is relatively introverted and autistic, and doesn't like to communicate with others. When he concentrates on research and work, he would be so focused that he forgets everything else.

Perhaps it is this kind of character that helps him move one step closer to the top.

"He."

Mei Hong smiled awkwardly but politely.

"He is not easy to communicate with. When we were forming a team for mathematical modeling, he and his teammates broke down before they even started training. According to students' feedback, he is very stubborn. Although he has strong execution ability, he will not listen to other people's opinions if there is a disagreement, unless..."

"Unless what?"

Xu Qingshan was thinking.

"Unless the other party can convince him."

Xu Qingshan couldn't help but move his fingers.

Hey, what a cliché plot.

Are all arrogant geniuses like this? However, it seems that people like Yang Shu are rare in Jingda and Huaqing, and most of them will participate in discussions and learning.

"If it's you, maybe it can work."

Mei Hong glanced at Xu Qingshan and continued.

"After all, in terms of academic ability, he is not as good as you. In terms of the AI-related and machine learning fields he is currently working on in his laboratory, he is also not as good as you."

Mei Hong, on the other hand, began to think and compare seriously.

"If he has any advantage, it's that his programming skills are much better than yours."

"Now that I think about it, the two of you are a good match."

Mei Hong's eyes lit up.

"I was struggling with whether to keep him for you to choose. Just eliminate him. He ranked eighth in OJ, and that's even though he didn't finish all the questions."

Xu Qingshan asked with some curiosity.

"Teacher Mei, what's going on with this OJ ranking?"

Mei Hong suddenly realized.

"You forgot that no one introduced these basic things to you in Yuanpei."

"OJ stands for Online Judge. We are an online evaluation system for online programming competitions. It is mainly used for repeated submission and testing of program codes. Normally, every school will have its own OJ platform for students. New question banks will be updated from time to time, and students can practice on it by themselves."

"As for the ranking list, the more questions a student who has logged in to OJ solves, the higher their ranking will be. If the number of questions solved is the same, the one who takes the least time will be ranked higher."

"This kind of rules are actually not much different from the ICPC you will participate in later, but the rules of ICPC will be richer and more diverse."

After Mei Hong put it so simply, Xu Qingshan understood.

Isn't this the kind of arena where you challenge levels when playing games?

"So this Yang Shu is the person who ranks first in the number of solved problems?"

Xu Qingshan pointed at the numbers on the document.

"That's right. He seems to be trying to find his form and get ready to win first place. In the most recent question bank competition, the first place is a doctoral student from our School of Information Science and Technology named Chen Fangping, who is Lao Gao's favorite student."

"Do both PhD and undergraduate students compete together?"

Xu Qingshan was stunned for a moment.

Aside from himself, he had not expected that Kyoto would allow undergraduates and graduate students to compete equally in these competitions.

"Looking down on our own undergraduates?"

Mei Hong smiled and patted Xu Qingshan on the shoulder.

“Although you are indeed a bit ridiculously awesome, Qingshan, don’t underestimate other undergraduates.”

Although he said so, Mei Hong's tone was still very friendly and he did not mean to scold Xu Qingshan.

"After all, they are all top scorers in the college entrance examinations in their respective provinces, and they have won gold medals in competitions. Besides, we old guys are no pushovers, so is it strange to have some outstanding students?"

"The reason why Xu Chenyang and his classmates were called the golden generation and why so many top universities welcomed them with open arms and feet when they went abroad was because of the strong academic accomplishment and research talent they demonstrated during their undergraduate studies."

"I did not mean that."

Xu Qingshan explained with a smile.

"I just think the pressure at Kyoto University might be greater than I thought."

"Maybe, but it's easy for you."

Mei Hong shrugged and could not deny it.

"Just him."

Xu Qingshan thought about it and decided.

"I'll go talk to him in a few days."

"In a few days? The registration deadline is almost here."

Mei Hong took out a notice from the side, which was posted by their Institute of Information Science and Technology.

"The competition will be on September 9th. Today is the 20th. The registration deadline is 18 noon tomorrow."

Mei Hong said with a frown.

"If you really want to talk to him, I have no objection. I have also prepared a replacement for you. But you have to be mentally prepared. The temporary replacement has limited strength. I recommend that you talk to the other two undergraduates in the top ten of OJ."

"It's okay, Teacher Mei, I'll try."

Xu Qingshan smiled and shook his head.

"Just him."

"Okay, here's his contact information. Normally, except for classes, he's in the AI ​​Algorithm Laboratory at the School of Information Science and Technology."

"Thank you, Teacher Mei."

"Then I'll take you there now." Mei Hong simply tidied up the table and prepared to take Xu Qingshan to find Yang Shu.

Xu Qingshan did not refuse.

The two of them left the office and walked through two buildings before arriving at the computer room of the AI ​​algorithm laboratory. Mei Hong remembered it clearly.

"Poplar? Poplar?"

I entered the algorithm laboratory. At this time of the evening, normally everyone else would have gone home.

Computer-related laboratories are different from those that do experiments in chemistry and biology. In fact, more people use their computers to complete some work in their dormitories or other places, and not many people will actually stay in the laboratory for the whole day.

The lights in the laboratory were on at this time, but no one was visible.

Xu Qingshan frowned. Is the person not here?
"Yang Shu! I'm out. I have something to talk to you about."

Mei Hong shouted at the top of his voice.

As he shouted, he turned off the lights in the laboratory and started looking around to see where the lights were on.

Only after confirming that there was a faint light coming from an inconspicuous corner did Mei Hong turn on the light again.

This surprised Xu Qingshan a little. Why did it seem that Dean Mei was very skilled in this whole process?
When the lights are turned on again.

Xu Qingshan saw a boy slowly crawling up from the corner.

He had been hiding behind the table and wearing headphones just now, no wonder I couldn't see him.

"Oh, it's like this again, let's go, let's go."

Mei Hong shook his head helplessly, looking at the boy who was at a loss and standing there, not knowing what to do.

"Yang Shu, what are you doing again?"

"."

Yang Shu pointed to the circuit board on the ground.

"Didn't I tell you not to solder circuit boards in the lab? Have you forgotten the lab safety rules again? Do you want your lab access card banned again?"

"without"

Yang Shu hurriedly waved his hands and explained.

"Look, there's no welding."

Xu Qingshan watched from the side.

This is what a real socially anxious and autistic person looks like, right?

"Come, let me introduce you to Xu Qingshan."

Mei Hong nodded, then motioned Xu Qingshan to come over and introduce him to Yang Shu.

Yang Shu looked at Xu Qingshan without any expression.

"Hello, Senior Yang Shu, nice to meet you."

But Xu Qingshan's outstretched hand received no response, and Mei Hong on the side rolled his eyes in annoyance.

Yang Shu is a sophomore and Xu Qingshan is a freshman, so there is nothing wrong with calling him senior.

"I'm not a senior."

But Yang Shu shook his head.

"What's up? No, I'm busy."

Even though the dean was standing next to him, Yang Shu still spoke with a wooden face.

"you"

Mei Hong was about to speak but was stopped by Xu Qingshan.

"It's like this, I'm going to participate in the ACM International Programming Contest, and I'd like you to be my teammate, okay?"

After getting to know Yang Shu, Xu Qingshan felt that he was actually the legendary academic master with low emotional intelligence but an IQ that was off the charts.

In fact, the emotional intelligence and IQ of most academic masters complement each other. Generally speaking, people with high IQs will not have low emotional intelligence.

If he behaves very low in emotional intelligence in front of you, it is most likely because in his cognitive judgment, you are not qualified for him to treat you with emotional intelligence, and he just needs to pursue his own happiness.

"No."

Yang Shu didn't hesitate and shook his head.

"Don't dare, right? Okay, then I'll go find Li Xiudao. He's ranked third, so he should be better than you."

Xu Qingshan said with a smile, his tone sounding somewhat sarcastic.

This made Mei Hong blink. Didn't they ask for him? Why did they ask for Li Xiudao? This wasn't a big problem. It was just that Li Xiudao was busy with a project recently. To convince him to participate, he needed to make some arrangements as the dean.

Yang Shu, who was originally planning to turn around and sit back in his original place, turned around again, stared at Xu Qingshan, and spoke word by word.

"He's not as strong as me."

"But he's third and you're eighth."

Xu Qingshan said lightly.

“That’s because I haven’t done it yet.”

Yang Shu said dryly.

"How can you prove something you haven't done? I haven't done OJ's questions yet. If I say that I could get into the top ten in one go, do you believe me?"

"No, I don't know you."

Yang Shu shook his head and continued.

"If I did it, I would be number one, I just don't bother to do it."

If someone else said this, they might be trying to save face.

But when Yang Shu said that, Xu Qingshan actually believed it. This guy didn't seem to care much about face issues, but he cared a lot about objective existence.

"Then let's make a bet. If my OJ ranking is higher than yours before noon tomorrow, you will join my team."

Xu Qingshan said.

Yang Shu was silent for a moment and nodded.

"it is good."

Currently, Yang Shu ranks eighth on the OJ platform, with a total answering time of 7 hours.

Even if Xu Qingshan tried his best, it would be difficult for him to answer so many questions at once within 7 hours.

To know.

The human brain is not a computer. It cannot operate at a high intensity for many hours with as little error as possible and answer the question successfully in one go.

Because it's on the OJ platform.

If the answer is not passed, there will be a penalty.

Just like Yang Shu’s total answering time of 7 hours, it refers to the sum of the time for all passed questions, plus the penalty time for each failed submission. OJ from Beijing University will accumulate an additional 10 minutes of penalty time for his failed submission.

In other words, assuming Xu Qingshan submitted 40 failed answers to the first question, he basically sent it in.

Because on some OJ platforms, the penalty for failing is only calculated once, but the penalty for the Beijing University question bank is calculated on a per-time basis.

This makes the challenge Xu Qingshan mentioned seem even more difficult.

Even for Yang Shu himself, it took him a whole week to complete the 7 hours of answering.

If Xu Qingshan really succeeded, Yang Shu felt that he had no reason to refuse.

"Okay, then it's settled. Teacher Mei, let's go and take him to sign up tomorrow."

Xu Qingshan smiled.

Only after the two of them left the laboratory did Mei Hong react.

"Qingshan, you haven't tried the questions on the OJ platform yet, right? Is this the agreement?"

There is one more update, and I will start to collect chapters from tomorrow night. I will start to stabilize my work and rest schedule in the next few days and fix a stable updating time.
