I am a great scientist

Chapter 50 Hello Professor Fang
According to the address on the text message, Zhou Xing rushed to a community called Weixiu Garden in the west gate of Peking University. It was built in an old garden left over from the Qing Dynasty. It is surrounded by mountains and rivers, with ancient ginkgo trees and beautiful scenery.

Zhou Xing bought a basket of fruit at a fruit shop in the community, and then searched according to the picture, and found Professor Fang's residence, a unique courtyard house.

"Knock, knock..." Zhou Xing reached out and knocked on the closed door.

"Hello, is Professor Fang at home?" Zhou Xing asked loudly:
"Yes, wait a moment." A steady voice came from inside the room:

Soon, there was a sound of unhurried footsteps from far and near, with a "creak", the door opened, and an old man with mixed black and white hair came into Zhou Xing's eyes. Glasses, thin and tall, with a ruddy complexion, and a pair of experienced eyes with suspicion.

The old man half-opened the door and looked Zhou Xing up and down: "Young man, who are you? What can I do for you?"

"Professor Fang, hello, my name is Zhou Xing, a student from Class [-] of the Zhike Department, I am here to greet you at the entrustment of Professor Chen!" Zhou Xing introduced himself:

"Well, I know you. I talked to Professor Chen on the phone just now. Come in!" Professor Fang opened all the doors to make way for Zhou Xing:
"Thank you, Professor Fang!" Zhou Xing nodded happily, and stepped into Professor Fang's home.

Walking into the room, you will be greeted with a scent of books. The lacquered wooden floor, classic wooden furniture, and landscape paintings hanging on the walls are full of nostalgic and classic atmosphere.

"Sit down, Class [-] of the Zhike Department, are you a freshman this year?" Professor Fang invited Zhou Xing to take a seat and asked:

"Yes, professor, I happen to be your student!" Zhou Xing put the fruit basket on the table, sat on the mahogany chair, nodded and said:
I and Chen Jianbin were just acquaintances, and there was no deep friendship. Zhou Xing must have asked for something when he came to visit. Professor Fang asked inquiringly: "En! What's the matter? The class starts tomorrow."

"Professor, I have some academic questions and I want to ask you. I can't wait for tomorrow. Are you free?" Zhou Xing looked at Professor Fang with Chicheng eyes:
Professor Fang was stunned for a moment, and said strangely: "Academic problem? Isn't my class still in session?"

"Professor, I'm more interested in this major, so I've done some self-study in advance, and encountered a few problems, so I came here to ask you for advice!" Zhou Xing said shyly:
Hearing this, Professor Fang was dumbfounded for a while, not knowing what to say.

At this moment, Zhou Xing gave people the impression that he was a reckless boy who was eager to learn. In order to ask a question about his studies, he actually sent Professor Chen Jianbin to intercede. Professor Fang thought that Zhou Xing had some troubles and needed his help!
Isn't it the teacher's job to help students solve their doubts!

"Looking at Professor Chen's face, I have to take the time to answer you if I don't have time! If you have any questions, feel free to ask!" Professor Fang smiled happily:

"Thank you, professor. I encountered a problem in learning the multi-objective Pareto optimal solution algorithm. How to set the boundary between the fuzzy value and the optimal value, and accurately determine the optimal calculation goal?" Zhou Xing asked urgently:
Hearing this, Professor Fang frowned, looking at Zhou Xing with a weird look.

"Multi-objective optimization calculation means that under constraints, there are two or more objectives, and there are conflicts among these calculation objectives, which cannot be solved at the same time, that is to say, the calculation of one objective is often at the expense of other objectives. The calculated value is at the cost of setting the peak value of the conflict in advance,..." Professor Fang thought for a while, and answered Zhou Xing:
While answering the questions, Professor Fang paid close attention to Zhou Xing. Seeing that he was stunned, his doubts became heavier. The question Zhou Xing asked involved a relatively in-depth multi-objective algorithm in the field of intelligence, which was not for beginners. the scope involved.

"Thank you, Professor. I understand this problem. First set the contradictory value, and then define the optimization." Zhou Xing nodded happily, thanked Professor Fang gratefully, and continued to ask: "Professor, I have another The problem is an experiment about fuzzy strategy calculation. The experimental steps are as follows: design a chip, control the water inlet valve S1 and water outlet valve S2, automatically control the water level to 0, ..., the control amount U is the output of fuzzy control , U consists of the deviation matrix e and the fuzzy relationship matrix R,..., the experiment failed, and I teach you that something went wrong in that step.”

Listening to Zhou Xing's eloquent talk about difficult problems, Professor Fang couldn't help but sit up straight, and listened with pricked ears. The problem Zhou Xing described was about fuzzy control algorithms, and it also involved very in-depth knowledge points in the field of intelligence.

After listening to the question, Professor Fang frowned and thought for a while, and replied: "In this experimental case, the customized observation and control quantities are correct, the five fuzzy sets of input and output are correct, and the customized fuzzy rule settings are biased. , Have you combined the neural network to learn the fuzzy rules? You did not do a good job in the defuzzification processing and settlement of the control amount,..., so it will lead to data errors."

"So that's it, I understand!" Zhou Xing looked happy, looked at Professor Fang gratefully, and continued to ask for advice: "Professor, I still have a question, it's still an experiment,..."

Listening to Zhou Xing's description of the experimental steps, Professor Fang looked solemn, frowned and thought before answering: "This experiment involves a simulated annealing algorithm, and it is introduced into an acceptance probability P,...."

Hearing Professor Fang's answer, Zhou Xing suddenly understood, thanked him gratefully, and then continued to ask for advice.

"..."

A question and an answer, unknowingly lasted for nearly two hours.

With a sound of "click", there was a sound of opening the door in the house, and a woman in her fifties came out of the bedroom in the house, and looked at the old and the young in the hall in the hall in amazement. .

The middle-aged woman watched for a long time, only to find that they were too busy talking and neglected themselves.

"Old Fang, there is a student here! Who is this?" The middle-aged woman interrupted their conversation helplessly when she saw this:

"Well, this is my student - Zhou Xing, and this is your teacher's wife - Chen Yi." Professor Fang stopped talking, looked at his wife and introduced Zhou Xing with a smile:

"Master, hello!" Zhou Xing quickly got up from his chair and greeted:

"Yeah, good boy, let's have dinner at home tonight! Lao Fang, I'm going grocery shopping, so I won't disturb your chat!" Chen Yi smiled slightly at Zhou Xing, and said wittily:

"No need for Mrs. Ma, I still want...!" Zhou Xing immediately waved his hand and refused:
"What else do you want? I'll eat here tonight. We can continue with the question just now! Or are you leaving soon?" Professor Fang interrupted what Zhou Xing hadn't said yet, and asked with a dark face:

"That, that, then I'm not welcome! I still have a lot of questions!" Zhou Xing looked at Professor Fang's old face blushing slightly, and said embarrassedly:
Hearing this, Professor Fang smiled wryly with an expression of wanting to cry.
