From a university student to a chief academician

Chapter 75 Academician Visits Ye Fei
Next, the data summary, technical report and waiting for the acceptance of the above.

And Ye Fei returned to Zhonghu University the next morning.

A few days later, a group of experts came to Jiangcheng Laboratory.

This group of experts are all top domestic laser experts, and the team leader is a laser academician.

The higher-ups attached great importance to the experiments in the Jiangcheng Laboratory. When they heard that the technical blockade had been broken, the higher-ups were very excited and immediately sent a group of strong expert teams to check and accept.

Professor Ma led the expert team all the way to the laboratory, and said: "Our experiment took five years, from the scanning speed of [-] at the beginning, to [-]."

Academician Cai asked: "According to the information you uploaded, I heard that the scanning speed of your experiment reaches more than [-], and the laser power is even less than [-]."

"Why did it suddenly jump from two thousand five thousand to three thousand?"

The rest of the experts also looked at Professor Ma suspiciously.

A smile appeared on Professor Ma's face: "Listen to me slowly."

"Ten days ago, our experiment encountered a dilemma. When the scanning speed increased, the laser power would increase, and when the laser power decreased, the scanning speed would decrease."

"You also know that the increase in laser power has an impact on the authenticity of the laser test."

The crowd nodded, indeed.

"At this time, we saw a paper published by Ye Fei of Zhonghu University, based on the Gaussian circle optimization method based on the response surface method and particle swarm optimization."

"The algorithm part found in it just happened to be helpful to our experiments."

"At that time, I was also a dead horse as a living horse doctor."

"But I didn't expect..."

When he said this, Professor Ma's eyes lit up.

Everyone raised their hearts and looked forward to Professor Ma's next answer.

Professor Ma said: "I didn't expect Ye Fei's algorithm to be so magical. It not only reduces the laser power, but also increases the scanning speed by more than [-]."

"The scanning speed exceeds [-] when the laser power is less than [-]."

"Huh..." All the experts exclaimed, inexplicably horrified.

Academician Cai asked in surprise: "The algorithm has such a big effect?"

This breaks his understanding of the algorithm. Previous algorithms have also been used in experiments, but they are only auxiliary.

What really matters is the experimental technique.

Professor Ma said helplessly: "I don't believe it either, but the facts are like this. I can't lie to you, right? It's not good for me either!"

Everyone nodded. Logically speaking, it was true. Professor Ma lied to them, and it would not do him any good.

Moreover, Professor Ma is obviously flattering Ye Fei, and it's not good for him.

"Let's go." Academician Cai urged: "Let's go and see what algorithm Ye Fei used and how to achieve such experimental results."

Everyone nodded slightly, and they were also looking forward to it.

After everyone saw Ye Fei's algorithm, they were still very confused.

Academician Cai understood a little bit, but he was a little confused in some places.

Academician Cai looked at the crowd and said, "Everyone, do you understand?"

Everyone shook their heads slightly, and one of them smiled wryly: "We know the particle swarm algorithm. From the perspective of Ye Fei's algorithm, he established a mathematical model through experiments, and then combined the mathematical model with the optimized particle swarm algorithm to obtain the optimized algorithm. combination of experimental parameters."

"But then we couldn't read it."

Academician Cai let out a sigh of relief, and said, "It seems that we still need to ask Ye Fei for advice."

"Everyone, Zhonghu University is in the next province. If you are not in a hurry, we will go to Zhonghu University to visit Ye Fei together."

Everyone nodded: "No problem."

After visiting the experiment, Academician Cai passed the news to the higher authorities.

And they went to Zhonghu University.

Office of the President of Midlake University!
Hearing from the secretary that academicians and some experts came to visit the school, the principal was surprised: "Why did they come to visit? Our school hasn't produced any major experimental results recently!"

The secretary shook his head and said, "I said I wanted to ask Ye Fei some questions."

There is no priority in learning, and those who have achieved it come first!
They don't know how to ask Ye Fei for advice, there is nothing to be ashamed of.

"Ask Ye Fei!" The principal was surprised.

In the past, these academicians and experts could not be invited by themselves.

Now he came to Zhonghu University because of Ye Fei.

What did Ye Fei do?

Let them come and ask for advice in person.

The principal asked, "When will they arrive?"

"Arrive around two o'clock this afternoon!"

The principal said solemnly: "Immediately call the deans of each college for a meeting in half an hour, and call Ye Fei as well."

"Okay, Principal!"

In half an hour, the conference room!

When the deans of the colleges heard that an academician and a group of experts were coming to Zhonghu University because of Ye Fei, everyone looked at Ye Fei in shock.

Ye Fei rubbed his nose, and sat on the seat a little uncomfortably.

The principal said: "They will arrive around two o'clock in the afternoon, and all of us will go to the school gate to meet them."

"Good!" Everyone nodded.

There are very few academicians of Zhonghu University, and there is no laser academician.

And this time, not only the academicians of the laser academy, but also some experts in laser science, the lineup is very luxurious.

In addition, the laser laboratory of Zhonghu University will be completed soon.

Zhonghu University may be able to reach some cooperation with these laser experts and academicians.

Therefore, Zhonghu University must come up with high standards to receive these people.

At around 01:30 in the afternoon, the principal and the deans of the colleges were waiting at the gate of the school, and Ye Fei was among them.

It stands to reason that they should hang up banners, but the time is too tight, people will arrive in the afternoon after receiving the news in the morning.

Banners didn't have time to prepare, so they didn't prepare banners.

Many students around were watching curiously, not knowing what the principal and deans were doing.

Around two o'clock, a bus drove over and stopped at the school gate.

A group of people got off the bus, led by Academician Cai.

The principal greeted him with a smile, and said, "Welcome Academician Cai and all the experts to Zhonghu University."

Academician Cai shook hands with the principal, and said with a smile: "This time, I have to trouble Principal He."

The rest of the experts shook hands with the deans.

"Should be." The principal waved back and said with a smile, "Ye Fei, come here quickly."

Ye Fei stepped forward, Academician Cai looked at Ye Fei and said with a smile, "Hi, Ye Fei, I'm sorry to trouble you this time."

Ye Fei shook hands with the other party and said with a smile, "No trouble."

In fact, I feel helpless in my heart, although such a thing can win the attention of some big shots.

But I would rather stay in the office and do math research, and I don't want these people to bother me.

At the same time, they were puzzled, what should they ask themselves?
Many students around knew Ye Fei, and one of them looked at Academician Cai and exclaimed, "That is the No. 1 laser science in my country, Academician Cai Yuanli."

The list and photos of Xia Guo academicians can be easily found on the Internet.

After the students around heard it, many of them took out their mobile phones to check.

After a while, everyone looked at Ye Fei in surprise.

"I'll go, Ye Fei is awesome, and he shook hands with the academician. Seeing the smiling face of Academician Cai, he is very kind to Ye Fei!"

"If I have this deed, it will be enough for me to boast for a lifetime."

"So, you are not Ye Fei, you see Ye Fei, he is not surprised by favor or humiliation."

"Really awesome, this may be the treatment of a student god!"

"..."

The students around were stunned.

The principal saw the commotion all around, and everyone stood at the door, being watched by the students like monkeys.

The principal said: "Everyone, let's go to the meeting room!"

"En!" Everyone nodded.

Along the way, the principal introduced the laser laboratory of Zhonghu University.

But Academician Cai and others seemed to be out of focus on this, and asked Ye Fei about the particle swarm algorithm from time to time.

After the dean saw it, well, let's not talk about the laser laboratory for now.

After Academician Cai and others have finished asking Ye Fei's questions, let's talk about the laser laboratory!
After entering the meeting room, the principal said, "Academician Cai, what questions do you want to ask Ye Fei, you can ask them directly now."

"Okay!" Academician Cai was very satisfied with the principal's knowledge, looked at Ye Fei and said, "Ye Fei, we just came from Jiangcheng Laboratory, and want to ask how you use algorithms to help Jiangcheng Laboratory break the technical barriers of lasers."

"What?" The principal and all the deans looked at Ye Fei in surprise.

Help Jiangcheng Laboratory break the laser technology blockade?
They didn't know about this. Only the dean of the School of Mathematics knew that Ye Fei was going to Jiangcheng Laboratory.

But the dean of the School of Mathematics didn't know about breaking the technological blockade.

The dean of the School of Mathematics was surprised at this moment. He just asked Ye Fei to help, but he did not expect to let the laser of Jiangcheng Laboratory break through the technical blockade.

Everyone knows what tech blockade means.

It means that the laser technology content of Jiangcheng Laboratory has reached the world-class level, and it can compete with those countries that have the most top-notch lasers.

Ye Fei hesitated and said, "Academician Cai, I don't think I can talk about this. After all, the laser technology of the Jiangcheng Laboratory belongs to the state."

Every technology that breaks the technology blockade will be blocked by the state, and ordinary people cannot view it.

Moreover, lasers play an important role in many aspects of the country.

Academician Cai said: "I'm sorry, I didn't introduce myself."

"This time we were entrusted by the higher authorities to review the experiments in the Jiangcheng laboratory."

"So, you can safely tell us about the Jiangcheng laboratory."

"Okay!" Ye Fei nodded.

He believed Academician Cai's words, and did not believe that Academician Cai would lie to him.

Even if they lied to him, academician Cai and the others would have nothing to eat if the people above knew about it.

You can think of this truth with your butt.

Ye Fei looked at the principal.

The principal smiled and said: "Well, you guys talk, we have something to go out first."

After finishing speaking, the principal greeted all the deans to leave the meeting room, leaving room for Academician Cai and others.

All the deans were surprised by what Ye Fei did, and they haven't returned home yet.

He walked out of the meeting room with a look of horror.

After the principal and others left, Ye Fei said: "I first established a mathematical model for the laser, and then combined the mathematical model with the algorithm to obtain a combination of experimental parameters. At this time, the laser power is within [-], and the scanning speed exceeds [-]."

"Concerning the mathematical model, I adopt the mathematical model of the relationship between the Box-Behnken experimental design method and the laser parameters..."

After listening to Ye Fei's explanation, everyone nodded in a sudden realization.

So this is ah!

After a long time, Ye Fei stopped explaining and said, "This is the algorithm I built for Jiangcheng Lab, everyone, is there anything else you don't understand?"

One of the experts asked: "Ye Fei, what is the combination of the improved particle swarm algorithm and the mathematical model of the corresponding surface method?"

Ye Feidao: "As the number of iterations increases, the particle swarm in the group is close to the optimal value..."

Another expert asked: "What about the optimization of experimental parameters based on particle swarm optimization!"

Ye Feidao: "Each particle in the particle swarm algorithm has its own position and velocity..."

Half an hour later, Ye Fei answered all the questions from everyone.

Academician Cai nodded in his heart: "It's not easy, you have such a deep understanding of mathematics at such a young age."

"Hey..." He sighed in his heart: "Mathematics is indeed the world of geniuses. If I study mathematics, he may not be able to achieve half of his abilities."
