Monday, a normal day.

The professional course of "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 non-homochicine vibration equation", which is the knowledge point that has been passed before, Wang Hao does not know the basic situation of the student, or spends time repeating it.

Then, the lecture begins.

Because of the previous repetition of the original knowledge points, a certain amount of time was delayed, and his class dragged on for more than fifteen minutes.

This is where the effect of demanding harshness comes into play.

There were no student complaints.

In other words, a large number of students were dissatisfied, but they did not dare to express their dissatisfaction, but when the end of the class was announced, many students sighed with relief.

"Starving!"

"It's a serious drag!"

"That's Wang Hao, Teacher Wang, what's the way? Why don't you report it? Maybe it helps? ”

"Forget it......"

New courses bring new inspiration.

Wang Hao settled the tasks related to the 'non-homogeneous problem', obtained seven teaching coin rewards, and created tasks related to 'Cauchy', which belonged to 'Task 2', and the difficulty evaluation also reached the C level, which is not bad.

[Task 2]

[Research on the Transformation and Algorithm of the Cauchy Problem.] 】

[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 still 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 100, it means that the inspiration and knowledge are enough to support the completion of a study.

Even if he doesn't use the 'Inspiration Burn' function, he can still achieve results through serious research.

This is Wang Hao's conclusion.

He took a closer look at the system and found that the 'Inspiration Burn' function is not against the sky, and there is another thing worth noting.

Teaching Coins!

You can get a certain amount of teaching coins when you settle tasks, but the exchange of inspiration points and teaching coins for C-level difficulty tasks is only '2 to 1'.

100 inspiration points, and 50 teaching coins for settlement.

D-level difficulty, it's simply '5 to 1'.

This rate is very pitiful, considering that every time you settle, the inspiration value will not exceed 100, and you will not get many teaching coins for settlement.

'Not much', as opposed to 'gain new abilities'.

The system clearly indicates that to obtain the next ability, you need to accumulate 10,000 Teaching Coins.

10,000!

Get ten teaching coins every day, and you don't use any of them just to accumulate, which also takes a thousand days to complete.

On weekends, it's hard to get ten teaching coins.

Giving lectures, doing R&D, or studying, reading books, using 'Teaching Coins' to enter Focus mode is the best choice.

Again, this is when TeachCoin has never been used for anyone else.

Getting ten teaching coins a day is just barely enough, and the teaching coins for task settlement can be saved, but it seems that there is no end to accumulating '10,000 teaching coins'.

[Teaching Coins: 61.] 】

Values are proof of this!

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

Therefore, if you want to accumulate more teaching coins, you still have to be 'frugal' in the task, and if you can spend a few hours to straighten out the content and complete the corresponding research and development and results, there is no need to consume a hundred inspiration points in one go.

Inspiration is equivalent to Teaching Coins.

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

"That's the way to do it."

Wang Hao carefully recorded the knowledge and inspiration in his head, and decided to give it a try by himself.

[Use the Teaching Coin to enter Focus Mode for one hour.] 】

Wake up your brain and get to work!

……

When Wang Hao enters the focus mode, ordinary things can't bother him at all, unless it is calling his name or touching his body, the brain nerves will subconsciously react, and it will make him come back to his senses.

People in the office are used to it.

They still have to do what they have to do, they will talk out about an issue, and there will be students coming in and out of the office.

None of this seems to matter.

Zhu Ping also noticed when she came in from outside, she pointed at Wang Hao with her finger and looked at the others, and pouted vigorously, as if to say, "This guy, it's started again?" ”

Several people nodded along with each other.

Zhu Ping answered in the seat, looked in the direction of Wang Hao, and whispered to Yan Jing, "I feel that he is a machine, a working machine." ”

"But the way he's focused, it's pretty good!" She said this but looked at Yan Jing with an intriguing smile on her face.

Yan Jing's face turned red suddenly, and she immediately pretended not to care, "Yes, he's so serious." ”

Zhang Zhiqiang walked in from outside, he was not interested in Wang Hao's serious work, because he was also very serious, and every time he came to the office, he was also working, researching topics, code, writing papers, and so on.

There's a lot to do.

He is already preparing to take graduate students, and he has also begun to think about how to take students and what projects to do with students.

However, this time he stopped.

He stopped at the door and stood behind Wang Hao, looking at the screen of his laptop, which was dazzling with lines of code.

Zhiqiang Zhang is a Ph.D. in informatics, very familiar with code, proficient in a variety of complex algorithms and methods.

Now the code written by Wang Hao, he can't understand it, of course it's normal, but he can understand that it's a 'data representation method'.

"What is this?"

Zhang Zhiqiang patted Wang Hao on the back and asked with curiosity.

Wang Hao immediately reacted and explained, "Cauchy problem, non-negative matrix factorization. ”

"Cauchy, graphics algorithms?"

"Hmm~~~"

Wang Hao hesitated for a moment and replied, "No, I do mathematical work, 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.

Zhang Zhiqiang holds a Ph.D. in informatics and is very interested in computer algorithms.

What he does is computer mathematics research, in short, it is to use computer methods to express the content of mathematics, and the research has not yet been completed, maybe discussing it with Zhang Zhiqiang can also bring some very key inspiration.

"I'm factoring Cauchy's non-negative matrices, expressing them in another way, and then solving the problem with computer methods."

"Most of it is the math part, and the analysis of non-negative matrix factorization will become more complex, and the values will become more, which is just the feeling of the human brain."

"If it's a computer, it's even 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 it becomes very complicated to read by expressing '10 to the 30th power' as '30 10s multiplied'.

Computers are different.

Because computers are mechanical, the representation of '30 10s multiplied' is easier to parse than a single large number.

Such is the case with Wang Hao's research.

Cauchy non-negative matrix factorization, which is not easy to represent, but transformed into a completely new model, it is not easy for the human brain to understand, but it is easier for computers to parse.

The more Zhang Zhiqiang listened, the more energetic he became.

Cauchy model is widely used in the field of computers, the most important is computer graphics, the classic application is face recognition, Cauchy model algorithm, can help the extraction accuracy of target contour parameters.

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

Zhang Zhiqiang said several words in a row on the computer, and the discussion between the two was also heard by others.

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

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

Wang Hao said, "The research is not a problem. My idea is to simplify the math and then extract the substitution and design a few packages corresponding to the corresponding branching functions......"

He said it in detail.

When explaining in depth, Zhang Zhiqiang could still understand some and give some ideas and suggestions, so the two discussed seriously.

At this time, Zhu Ping stopped talking.

She is also a lecturer in the direction of informatics, and she was very actively involved just now, and she simply stood next to her, hoping to participate in the professional discussion.

As a result, I can't understand when I get to the point.

The wind is sluggish......

She very much wanted to join the discussion, but she only felt the bitterness of being crushed by two top students, and Zhang Zhiqiang was originally a doctor of informatics, with the results of top journals in computer science, and was about to be promoted to associate professor.

Wang Hao is a doctor of mathematics!

The knowledge of a Ph.D. in mathematics in the field of informatics crushed her as a university lecturer in the field of informatics.

"ε=( ́ο'*))), alas!"

Half an hour later, the discussion finally ended.

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

Zhu Ping's eyes lit up.

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

"Awesome!"

Zhang Zhiqiang also gave a thumbs up with amazement.

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

Everyone else thought it was a sign of 'humility'.

Zhu Ping glanced at Zhang Zhiqiang, and thought disdainfully, "Look at Wang Hao, what did you say about the four SCI articles in two weeks?" Look at Zhang Zhiqiang, show off every day! ”

"The gap between people and people!"

"Moreover, 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 the review fee cost more than 1,000 US dollars, and one of them does not require a review fee.

He studied it carefully, and the royalty was probably around four thousand dollars.

Four thousand dollars!

The money in the bank card is all added up, and it is not enough to pay the royalties, and he is also concerned about the 'salary date'.

Wages, obviously, will not solve the problem.

Wang Hao has been counting the time, "Computer Mathematics and Information Engineering" will be released in the evening, after the release of the new issue of "Computer Mathematics and Information Engineering", how long will it take to get the school's subsidy for papers?

This is already very important!
