City in its prime.
Fu Shuo asked Yong Han: "Have you seen the news released in the city? I want to ask who can provide an algorithm to increase the speed of fluid simulation."
Yonghan said: "I saw it. What does this have to do with us?"
Fu Shuo said: "There is a reward."
Yonghan said: "I don't know how to offer a reward. By the way, you are a computer major. You know how."
Fu Shuo said: "I'm not going to take this task, and I'm not familiar with it. But my uncle can. His name is Fu Zhu."
Yonghan said: "Then you go to your uncle and ask."
Fu Shuo said: "He doesn't have time to take care of small things. I'll just go and ask."
Fu Shuo came to Fu Zhu's office.
Fu Shuo said: "Do you know the algorithm to improve the speed of fluid simulation?"
Fu Zhu said: "This is a good research topic. But now I have other things."
Fu Shuo said: "This is also a big event. I heard it is related to Tengcheng waters."
Fu Zhu said: "Oh. That's quite important. But there are still things to do. I will consider it after it is dealt with."
Fu Shuo said, "What else is so important?"
Fu Zhu said: "Have you ever heard of the Shuicheng Numerous Formation?"
Fu Shuo said, "No."
Fu Zhu said: "I am busy with this matter."
It was a misty early morning, with clouds and mist floating all over the sky, and the station was dark. The station was packed with people.
There was a young man standing at the exit. Full forehead, gently combed hair. There are two thick eyebrows, and there is a heroic spirit between the eyebrows. The eyes show abundant energy. The angular face has a slight beard. Tall and slim. Pensive expression. His name is Zhan Guyue.
Fu Zhu's student Zhan Guyue was invited by Jiang Jue to take a train and hurriedly came to Shuicheng to look for traces of Tang Yihuai.
Fu Zhu just stayed in his research institute and refused all the invitations from his friends. Zhan Guyue clicked on the computer all day long and had no time or habit of going out.
Zhan Ding had arrived at the station, greeted him with a paper sign, and said to him: "Hello, I am the landlord Zhan Ding. I am waiting for you to come over here. Jiang Jue must have invited you here."
"Yes, he invited Teacher Fu Zhu, but he was not available. So he sent me here."
"Please come with me and arrange to go to this small town. The roads are not easy to walk. I will take you to your accommodation and then walk around."
Get in a black car and follow Zhan Ding along the narrow road. Most of the buildings next to it are 6 floors or less, and there are also many bungalows. After passing the city center, there are more buildings, and then moving forward, there are more and more bungalows. Then houses gradually became scarce.
Zhan Ding said: "The town is small, not as prosperous as a big city, and has few entertainment facilities."
Zhan Guyue said: "It's okay, it's quiet here. There should be a lot of natural scenery."
Zhan Ding said: "Didn't Jiang Jue say what was discussed?"
Zhan Guyue said: "No. They are all doing research. They should be all about mathematical logic and the like."
Zhan Ding said: "We are here."
A courtyard with low walls and a brand new iron gate. After entering, the courtyard has green vegetation and two floors in the middle.
"This is a good living environment." Zhan Guyue looked around, "Everything inside is new. It should have been built not long ago."
"Several houses like this were built last year," Zhan Ding said.
"You took two boxes, let me help you carry them up."
Zhan Guyue said: "Thank you."
Zhan Ding said: "So many things?"
Zhan Guyue said: "Yes, after all, we have to live there for a while."
Zhan Ding said: "When all the guests arrive, I will take you out for a walk. If you need anything, please contact me."
Zhan Guyue said: "I hope Mr. Jiang will have a meeting with us as soon as possible."
After Zhan Ding left. Zhan Guyue opened the box and found books. In this discussion, we cannot embarrass the teacher in front of Mr. Jiang. He doesn't have a good impression of Mr. Jiang, but he is a senior after all and has a certain reputation in the algorithm world.
That night, another researcher came, Dong Chu. Wearing black pants and beige shirt.
The next day, a researcher came and arrived at the courtyard. "Hello, my name is Liu Mozhi. I am a staff member of the Institute of Mathematics and Physics. I am in the computer field." She was wearing a long-sleeved coat and skirt, and her voice was crisp and round.
Zhan Guyue said: "We are also from the Institute of Mathematics and Physics. My name is Zhan Guyue. I am in the direction of algorithms."
"My name is Dong Chu, majoring in mathematics."
Zhan Guyue said: "Nice to meet you."
Liu Mozhi said: "Did you all receive Jiang Jue's invitation when you came?"
Dong Chu said: "Yes."
Zhan Guyue said: "You are more professional."
Liu Mozhi said: "Have you heard of the Shuicheng Numerous Formation?"
Dong Chu said: "I have heard of this name, but I don't know what it does."
Liu Mozhi said: "I heard that its function is to simulate and describe the real world. There are also other opinions."
Zhan Guyue said: "Mathematics describes real time. Estimates are to express the real world with numbers. Then use mathematical formulas to describe the connections between things and make predictions. For example, regression analysis, neural networks, etc."
Regression analysis is a method of statistically analyzing data to understand whether two or more variables are related, the direction and strength of the correlation, and to establish a mathematical model to observe specific variables to predict the variables of interest to the researcher. Although there is no strict, deterministic functional relationship between the independent variable and the dependent variable, you can try to find the mathematical expression that best represents the relationship between them.
Dong Chu said: "I think it is modeling. Like mechanical modeling and fluid heat transfer modeling."
Liu Mozhi said: "Or we can conduct monitoring to prevent accidents from happening."
The continuous, gradual, and smooth motion change processes of many things in nature can be solved using calculus methods. Things proceed in a regular manner, so that people can accurately predict the future state of motion, which requires the use of classic calculus to describe. The basic concepts and content of calculus include differential calculus and integral calculus. The main contents of differential calculus include: limit theory, derivatives, differential calculus, etc. The main contents of integral calculus include: definite integral, indefinite integral, etc.
However, there are many processes of mutation and leap in natural and social phenomena. The discontinuity caused by leap makes the behavior space of the system non-differentiable, which cannot be described by calculus.
The process of developing from gradual change and quantitative change to sudden change and qualitative change is the phenomenon of mutation. In the past, scientists have encountered various difficulties when studying such mutation phenomena. The main difficulty is the lack of appropriate mathematical tools to provide mathematical models to describe them. Mathematicians further study mathematical theories describing catastrophe theory and studying discontinuity phenomena.
Catastrophe theory proposes a series of mathematical models to explain the discontinuous change process that occurs in natural and social phenomena, describing why various phenomena suddenly leap from one form to another that is fundamentally different. form. For example, a house suddenly collapses, a dam suddenly bursts, changes in liquid, gas, and solid water, and biological mutations.
Several people were discussing and speculating. Planning on walking around town.
