The next day is Monday, and the professional course "Partial Differential Equations" has entered a new content-high-dimensional wave equation.
The content of the first small chapter of the high-dimensional wave equation is the Cauchy problem. Cauchy belongs to the content of 'Solving non-homogeneous string vibration equations'. It is a knowledge point that has been passed before. Wang Hao does not know the basic situation of the students, or it takes time
Repeated it again.
Then, the lecture officially begins.
Because the previous knowledge points were repeated and a certain amount of time was wasted, his class lasted more than fifteen minutes.
At this time, the role of strict requirements becomes apparent.
No student is dissatisfied.
In other words, a lot of students were dissatisfied, but they did not dare to express their dissatisfaction. However, when the get out of class was announced, many students sighed in relief.
"starving!"
"It's a serious drag!"
"That's Wang Hao. Teacher Wang, what can you do? Why don't you report it? Maybe it will be useful?"
"Forget it..."
New courses can bring new inspiration.
Wang Hao settled the tasks related to the 'Non-Homogeneous Problem' and received seven teaching coins as rewards. He also created a task related to 'Cauchy' and placed it in 'Task 2'. The difficulty evaluation also reached level C, which is not bad.
.
【Task 2】
【Research on transformation and algorithm of Cauchy problem.】
[Inspiration value: 89 points.]
Although the inspiration value of the newly created Cauchy problem task could not be increased by more than one hundred points, and the inspiration value could not be consumed to straighten out the structure of knowledge and inspiration, Wang Hao still returned to the general office and recorded the inspiration in his mind.
The 'inspiration consumption' function in the task can indeed help to sort out the mind, but in fact, knowledge and inspiration already exist in the mind, and the 'inspiration consumption' function only helps to 'organize' it.
If the inspiration value exceeds one hundred, it means that the inspiration and knowledge are enough to support the completion of a research.
Even without using the 'inspiration consumption' function, he can still achieve results through serious and hard research.
This is Wang Hao’s conclusion.
After carefully studying the system, he found that the 'inspiration consumption' function was not unnatural, and there was another point worth noting--
Teaching coins!
You can get a certain amount of teaching coins by completing the tasks, but for C-level difficulty tasks, the exchange of inspiration value and teaching coins is only '2 to 1'.
One hundred inspiration points, and fifty teaching coins will be obtained after settlement.
Level D difficulty is simply ‘5 to 1’.
This ratio is very pitiful, considering that at each settlement, the inspiration value will not exceed 100, and the teaching coins obtained from the settlement will not be many.
‘Not much’ corresponds to ‘acquire new abilities’.
It is clearly marked in the system that to obtain the next ability, you need to accumulate 10,000 teaching coins.
Ten thousand!
Earn ten teaching coins every day. If you don't use any of them, you just accumulate them. It will take a thousand days to complete.
On weekends, it is difficult to obtain ten teaching coins.
Lecture every day, do research and development, or study or read books. Using "teaching coins" to enter the focus mode is the best choice.
This is without ever using the teaching coins on anyone else.
Getting ten teaching coins every day is just barely enough. The teaching coins for completing tasks can be saved, but accumulating "10,000 teaching coins" seems to be far away.
【Teaching Coin: 61.】
The numerical value is proof!
There were only about 60 teaching coins in more than half a month, and most of them were accumulated through the settlement of tasks.
Therefore, if you think of accumulating more teaching coins, you still have to be 'frugal' in tasks. If you can spend a few hours sorting out the content and completing the corresponding research and development and results, there is no need to consume a hundred inspiration points in one breath.
Inspiration value is equivalent to teaching coins.
"C-level mission, two to one, if you can get two hundred inspiration points, you will get one hundred teaching coins after settlement!"
"That's the good way."
Wang Hao carefully recorded all the knowledge and inspiration in his mind, and decided to try his own research and development.
[Use teaching coins to enter focus mode, which lasts for one hour.]
Wake up your brain and get to work!
…
When Wang Hao enters the concentration mode, ordinary things will not disturb him at all. Unless his name is called or his body is touched, the brain nerves will react subconsciously to bring him back to consciousness.
Everyone in the office is used to it.
They still do what they should do, they will discuss a problem aloud, and students will come and go in the office.
None of this seems to affect it.
Zhu Ping also noticed when she came in from the outside. She pointed her finger at Wang Hao and looked at the others. She also curled her lips vigorously, as if to say, "Is this guy starting again?"
Several people nodded along.
Zhu Ping replied sitting on her seat, looking in the direction of Wang Hao, and whispered to Yan Jing, "I feel like he is a machine, a working machine."
"But he's pretty good-looking when he's focused!" As she said this, she looked at Yan Jing with an intriguing smile on her face.
Yan Jing blushed immediately and immediately pretended not to care, "Yes, he is so serious."
Zhang Zhiqiang walked in from the outside. He was not interested in Wang Hao's serious work, because he was also very serious. Every time he came to the office, he was still working, researching topics, coding, writing papers, etc.
There are many things to do.
He was already preparing to take care of graduate students, and he also began to think about how to take care of students and what projects to do with them.
But this time he stopped.
He stopped at the door and stood behind Wang Hao, looking at the laptop screen. The lines of code on it were dazzling.
Zhang Zhiqiang is a doctor of information science. He is very familiar with codes and proficient in various complex algorithms and methods.
Now he can't understand the code written by Wang Hao, which is normal of course, but he can understand that it is a 'data representation method'.
"What's this?"
Zhang Zhiqiang patted Wang Hao on the back and asked curiously.
Wang Hao reacted immediately and explained, "Cauchy problem, non-negative matrix decomposition."
"Cauchy, graphics algorithm?"
"Hmm~~~"
Wang Hao hesitated for a moment and replied, "That's not really true. What I do is mathematics work, not computers, and it does not involve the application level."
Zhang Zhiqiang suddenly became more curious. He simply pulled his chair over and said, "Tell me about it."
Wang Hao didn't care either.
Zhang Zhiqiang has a PhD in information science and is very knowledgeable in computer algorithms.
What he does is computer mathematics research. To put it simply, it uses computer methods to express mathematical content. However, the research has not been completed yet. Maybe discussing it with Zhang Zhiqiang can bring some key inspiration.
"I decomposed the Cauchy non-negative matrix and expressed it in another way, and then used computer methods to solve the problem."
"Most of it is mathematics. The analysis of non-negative matrix decomposition will become more complicated and there will be more values. This is just the feeling of the human brain."
"If it were a computer, it would be simpler."
This is easy to understand.
It is easy for the human brain to understand the very large number '10 to the power of 30', but when expressing '10 to the power of 30' as '30 multiplied by 10', it becomes very complicated to read.
Computers are different.
Because computers are mechanical operations, the representation of '30 multiplied by 10' is actually easier to parse than a single very large number.
This is what Wang Hao's research is like.
Cauchy non-negative matrix decomposition is not easy to express, but it is transformed into a new model that is not easy for the human brain to understand, but becomes easier for computers to analyze.
The more Zhang Zhiqiang listened, the more energetic he became.
The Cauchy model is widely used in the computer field. The most important one is computer graphics. A very classic application is face recognition. The Cauchy model algorithm can help extract accuracy values of target contour parameters.
At the same time, the Cauchy model is complex to represent.
Zhang Zhiqiang talked several times about computers, and the discussion between the two was also heard by others.
Zhu Ping actively participated, "Cauchy model, I know this and have studied it. It is very important."
She then asked, "How did you achieve simplification?"
Wang Haodao, "There are no problems with the research. My idea is to simplify the mathematics, then extract substitutions, and design several packages to correspond to the corresponding branch functions..."
He spoke in great detail.
When the explanation was explained in depth, Zhang Zhiqiang was still able to understand a little bit and gave some ideas and suggestions. The two began to discuss it seriously.
At this time, Zhu Ping stopped talking.
She is also a lecturer in the field of informatics. She actively participated in it just now and even stood aside, hoping to participate in the professional discussion.
As a result, I couldn’t understand it when I got to the point.
The wind is rustling...
She really wanted to join the discussion, but she only felt the pain of being crushed by two top academics. Zhang Zhiqiang didn't care. He originally had a doctorate in information science, had top journal results in computer science, and was about to be promoted to associate professor.
.
Wang Hao is a Ph.D. in mathematics!
The knowledge of a PhD in mathematics in the field of informatics overwhelmed her, a university lecturer in the field of informatics.
"ε=(′ο｀*))), alas!"
After half an hour, the discussion finally ended.
Zhang Zhiqiang also commented, "This research is very valuable. It is estimated that it can at least be issued an SCI, and it is very useful."
Zhu Ping's eyes lit up.
She was not because of Wang Hao's research, but because she could finally join the topic instead of listening pitifully from behind, "Wang Hao, weren't there three papers last week? Another one this week? You are a machine!"
"
"Amazing!"
Zhang Zhiqiang also gave a thumbs up with wonder.
Wang Hao did not look happy, but became very depressed, and even sighed.
Others thought it was a sign of 'humility'.
Zhu Ping glanced at Zhang Zhiqiang and thought disdainfully, "Look at Wang Hao, four SCI articles in two weeks, what are you talking about? Look at Zhang Zhiqiang, showing off every day!"
"What a difference between people!"
"Besides, Wang Hao is also good-looking..."
In fact, Wang Hao is not modest at all. He is really sighing. He submitted four papers last week and spent more than a thousand US dollars in review fees, and one of them did not require review fees.
He studied it carefully and found that the publishing fee was approximately more than four thousand US dollars.
Four thousand dollars!
All the money in the bank card was not enough to pay the publishing fee, so he was also concerned about the issue of 'salary payment date'.
Wages obviously cannot solve the problem.
Wang Hao has been counting the time. "Computer Mathematics and Information Engineering" will be released in the evening. After the new issue of "Computer Mathematics and Information Engineering" is released, how long will it take to get the school's subsidy for the paper?
