From University Lecturer to Chief Academician

The next day is Monday, and the professional course "Partial Differential Equations" has entered a new content - high-dimensional wave equations.

The content of the first chapter of the high-dimensional wave equation is the Cauchy problem. Cauchy belongs to the content of "Solving the Inhomogeneous String Vibration Equation". Repeatedly.

Then, the official speech begins.

Because of the delay in repeating the original knowledge points, his class was delayed by more than fifteen minutes.

At this time, the role of strict requirements is revealed.

No student is dissatisfied.

In other words, a large number of students were dissatisfied, but they did not dare to express their dissatisfaction. It was just that when the get out of class was dismissed, many students sighed in relief.

"starving!"

"Severe delay!"

"That's Wang Hao, Mr. Wang, what can I do? Why don't you report it? Maybe it will help?"

"Forget it..."

New courses can bring new inspiration.

Wang Hao settled the tasks related to 'Non-homogeneous Problem', got seven teaching currency rewards, and created a task related to 'Cauchy', which belonged to 'Task 2', and the difficulty evaluation also reached C level, which is not bad .

【Task 2】

[Cauchy problem transformation and algorithm research. 】

[Inspiration value: 89 points. 】

Although the newly established Cauchy problem task failed to increase the inspiration value by more than 100 points, and could not consume the inspiration value and straighten out the structure of knowledge and inspiration, Wang Hao returned to the general office and recorded the inspiration in his mind.

The "inspiration consumption" function in the task can indeed help to straighten out the mind, but in fact, knowledge and inspiration already exist in the mind, and the "inspiration consumption" function only helps to "clean up".

If the inspiration value exceeds one hundred, it means that the inspiration and knowledge are enough to support the completion of a research.

Even if he doesn't use the 'inspiration consumption' function, he can still produce results through serious research.

This is Wang Hao's conclusion.

After careful study of the system, he found that the 'inspiration consumption' function is not against the sky, and there is another point worth noting——

Teaching coins!

A certain amount of teaching coins can be obtained for task settlement, but for tasks with C-level difficulty, the exchange of inspiration points and teaching coins is only '2 to 1'.

100 inspiration points, 50 teaching coins for settlement.

D-level difficulty is simply '5 to 1'.

This ratio is very pitiful. Considering that the inspiration value will not exceed one hundred in each settlement, the teaching currency obtained by settlement is not much.

'Not much' corresponds to 'gaining new abilities'.

It is clearly marked in the system that to obtain the next ability, one needs to accumulate 10,000 teaching coins.

Ten thousand!

Get ten teaching coins every day, don't use any of them just accumulate, and it will take a thousand days to complete.

On weekends, it is difficult to get ten teaching coins.

Lectures every day, do research and development, or study, read books, using the "teaching currency" to enter the focus mode is the best choice.

This is the case that the teaching currency has never been used on other people.

Obtaining ten teaching coins every day is barely enough. The teaching coins for task settlement can be saved, but the distance from accumulating '10,000 teaching coins' seems to be far away.

[Teaching currency: 61. 】

The numbers are the proof!

There are only more than 60 teaching coins in more than half a month, and most of them are accumulated through task settlement.

So thinking of accumulating more teaching coins, you still have to be 'thrifty' on tasks. If you can spend a few hours straightening out the content and completing the corresponding research and development, there is no need to consume a hundred inspiration points in one go.

Inspiration value is equivalent to teaching currency.

"C-level tasks, two to one, if you can get two hundred inspiration points, you will get one hundred teaching coins for the settlement!"

"That's a good way."

Wang Hao carefully recorded the knowledge and inspiration in his mind, and decided to do research and development by himself.

[Use the teaching currency to enter the focus mode, which lasts for one hour. 】

The brain wakes up and starts working!

...

When Wang Hao entered the concentration mode, ordinary things would not bother him at all, except for calling his name or touching his body, the brain nerves would react subconsciously to bring him back to his senses.

Everyone in the office is used to it.

They still have to do what to do, they will discuss a problem aloud, and students will come and go in and out of the office.

These seem to have no effect.

Zhu Ping also noticed when she came in from the outside. She pointed at Wang Hao and looked at the others, and pouted her lips vigorously, as if to say, "This guy, started again?"

Several people nodded together.

Zhu Ping answered the seat, looked in Wang Hao's direction, and whispered to Yan Jing, "I think he is a machine, a working machine."

"But he's pretty good-looking when he's focused!" As she said that, 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 very 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, codes, writing papers, and so on.

There are many things to do.

He was already preparing to lead graduate students, and he began to think about how to lead students and what projects he would do with students.

However, this time he stopped.

He stopped at the door and stood behind Wang Hao, looking at the laptop screen, the lines of codes on it made people dazzled.

Zhang Zhiqiang is a doctor of informatics, very familiar with the code, proficient in various complex algorithms and methods.

Now the code written by Wang Hao is somewhat incomprehensible to him. Of course it is normal, 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, "It's not counted. What I do is mathematics, not computers, and it doesn't involve the application level."

Zhang Zhiqiang suddenly became more curious, he simply pulled the chair over, "Tell me about it."

Wang Hao didn't care either.

Zhang Zhiqiang is a Ph.D. in informatics, and has a lot of research on computer algorithms.

What he is doing is computer mathematics research. To put it simply, it is to use computer methods to express the content of mathematics. The research has not yet been completed. Maybe discussing it with Zhang Zhiqiang can bring some key inspirations.

"I decompose the Cauchy non-negative matrix, express it in another way, and then use computer methods to solve the problem."

"Most of it is the mathematical part. The analysis of non-negative matrix factorization will become more complicated and the number will become more. This is just the feeling of the human brain."

"If it was a computer, it would be simpler."

It's easy to understand.

It is easy for the human brain to understand the super-large number '10 to the 30th power', but to express '10 to the 30th power' as '30 multiplication of 10' will become very complicated to read.

Computers are different.

Because the computer is a mechanical calculation, the expression of "multiplying 30 by 10" is easier to parse than a single super-large number.

Wang Hao's research is just like this.

Cauchy non-negative matrix decomposition is not easy to express, but it is transformed into a new model, which is not easy for the human brain to understand, but easier for the computer 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. The classic application is face recognition. The Cauchy model algorithm can help extract the accuracy value of the target contour parameters.

At the same time, the Cauchy model is complex to express.

Zhang Zhiqiang spoke several words in a row about computers, and the discussion between the two was also heard by others.

Zhu Ping actively participated in it, "Cauchy model, I know this, and I have studied it, it is very important."

She then asked, "How did you achieve the simplification?"

Wang Haodao, "There is no problem with the research. My idea is to simplify the mathematics, then extract and replace, design several packages, and correspond to the corresponding branch functions..."

He spoke in great detail.

When explaining in depth, Zhang Zhiqiang could still understand a little, and he could give some ideas and suggestions, and the two began to discuss seriously.

At this moment, Zhu Ping stopped talking.

She is also a lecturer in the direction of informatics. She actively participated in it just now, and even stood by the side, hoping to participate in professional discussions.

As a result, when I entered the topic, I couldn't understand it.

The wind is rustling...

She really wanted to join the discussion, but she only felt the anguish of being crushed by two bullies. Zhang Zhiqiang didn't care. He was originally a Ph.D. in informatics, and he had the results of top journals in computer science, and he was about to be promoted to associate professor. .

Wang Hao is a doctor of mathematics!

The knowledge of a doctor of mathematics in the field of informatics has crushed her university lecturer in the direction of informatics.

"ε=(ο｀*))), alas!"

After half an hour, the discussion finally came to an end.

Zhang Zhiqiang also gave a comment, "This research is very valuable. It is estimated that at least an SCI can be issued, and it is very useful."

Zhu Ping's eyes lit up.

It was not because of Wang Hao's research, but because she was finally able to join the topic instead of listening pitifully in the background, "Wang Hao, didn't there be three papers last week? Another one this week? You are a machine!" "

"Amazing!"

Zhang Zhiqiang also gave a thumbs up in amazement.

Wang Hao didn't look happy, but became very depressed, and even sighed.

Others thought it was a sign of 'humility'.

Zhu Ping cast a glance at Zhang Zhiqiang, thinking with disdain in her heart, "Look at Wang Hao, who wrote four SCI articles in two weeks, what did you say? Look at Zhang Zhiqiang, showing off every day!"

"The gap between people!"

"Besides, Wang Hao is also good-looking..."

In fact, Wang Hao is not humble at all. He is really sighing. He submitted four papers last week and spent more than a thousand dollars in review fees, and one of them did not require a review fee.

He studied it carefully, and found that the edition fee was around 4,000 U.S. dollars.

Four thousand dollars!

All the money in the bank card was added up, and it was not enough to pay the license fee. He also cared about the issue of the 'salary payment date'.

Salary, 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?

This is already very important!
