The time for the academic report speech of Hanghu Abayun R&D Center is set for the evening after tomorrow, and the schedule of two days and one night is still very tight.

This is also Wang Hao's request.

He just thought that after finishing his work, he would come back and continue his research, and the B-level difficulty 'partial differential equation' was already close to hundreds.

Wang Hao's goal was to be able to 'make up a hundred' before leaving, but the result was not satisfactory.

The next day, he gave a lecture on two equation solutions to the physics major, and the inspiration value of the task dropped sharply compared with the previous day, and in the afternoon he simply went to the library and read the professional book for three hours in a row, which only brought two inspiration points to increase.

[Task 1]

[R&D Project Name: Common Solution Method for Specific Partial Differential Equations (Difficulty: B).] 】

[Inspiration value: 98.] 】

Looking at the data displayed by the task system, Wang Hao let out a long sigh, he still chose to give up for the time being, anyway, there are only two inspiration points missing, maybe there will be a trip to Hanghu to give a lecture, even if he makes up enough one hundred before leaving, he has no time to study it at all, and he still has to wait until he comes back from Hanghu.

The study of 'partial differential equations' does take a lot of time.

Wang Hao thought about it carefully and thought that it was not a matter of difficulty, but the most important thing was that there was too much content.

Partial differential equations are a large category of study.

It's not like a math problem, as long as you solve it, it contains a lot of content, which means that you need more knowledge, more foundation, and more inspiration.

He was expecting something to come.

After coming out of the library, Wang Hao went to the academic affairs building to find the academic affairs department of the School of Science, and went to report as a substitute teacher.

Zheng Yaojun asked Wang Hao to teach on behalf of the course report, and also explained that Wang Hao is a doctor of mathematics in Donggang, and the content of his doctoral dissertation is related to differential equations, and he also serves as a lecturer of "Partial Differential Equations" in the school.

It was simple for Wang Hao to find Zheng Yaojun to speak on his behalf.

Several people in the Academic Affairs Section knew Zheng Yaojun, and a director surnamed Zhu suddenly said, "Zheng Dazui, right?" No problem. ”

Several people in the office burst out laughing.

"Zheng Dazui?"

Wang Hao pondered it carefully, and felt that the nickname of 'Big Mouth' was indeed so appropriate for Zheng Yaojun.

If you don't say it, you really haven't noticed it, Zheng Yaojun's mouth is really big.

"It's not right to laugh at other people's looks, it's not right to laugh at other people's looks, Zheng Dazui, Zheng Dazui......"

Wang Hao walked out in his heart, and couldn't help laughing when he got to the corridor.

in the office.

As Wang Hao walked out of the door, the topic immediately changed from Zheng Yaojun to Wang Hao, there was a female teacher with glasses, and her eyes flashed with an inexplicable light, "That's Wang Hao?" I've only heard about it before, and I'm so young! ”

Others chattered, "He made a mistake in scientific research, made the news, and only signed a one-year contract with the school." ”

"Donggang's doctor who stayed in school!"

"How else to say it? Talent is talent, I heard Li Ming say that he published three papers in one go, which were published in the top international journals together. ”

"A few professors in the School of Science, plus Director Zhu, and the dean or something, immediately decided to give him a special promotion!"

“……”

Wang Hao left the academic affairs building and ate in the cafeteria.

Subsequently, go home.

He opened the task system and looked at it, thought about it for a while, and decided to create a mission--

[Task 2]

[R&D Project Name: Fourier Transform Improved Multiplication Operation (Difficulty: B).] 】

[Inspiration value: 0.] 】

[The accumulation of inspiration points reaches 100 points, which can be consumed at one time to assist in obtaining R&D-related inspiration and knowledge related to the correlation of knowledge.] 】

[Task settlement, get the reward of teaching coins.] 】

Really!

Level B difficulty!

The improvement of multiplication operation by Fourier transform is a problem that the predecessor thought about during his doctoral studies, and hopes to improve the 'multiplication algorithm for large numbers' with Fourier transform as the core.

This is not a new topic.

The fastest existing 'multiplication algorithm for large numbers', related to the introduction of the Fourier transform algorithm, was completed by two mathematicians half a century ago, using the method of multiplying large numbers with 'n×log n×log(log n) times single digits'.

Fifty years ago, the multiplication of large numbers used the method of 'decomposing the multiplier of a large number into smaller parts'.

The new method simplifies about 165 trillion additional steps when multiplying between two billion digits compared to the old method.

However, the new approach is not new.

In the past 50 years, information technology has made tremendous development, and many fields need to multiply large numbers, but there is still no breakthrough in the research on multiplication of large numbers.

The predecessor carefully studied the multiplication algorithm of large numbers, and thought that it could find a way to introduce the Fourier transform algorithm that was 'more aesthetic', 'more simplified, and elegant' to perform the operation of multiplying large numbers.

Apparently.

The development of the system's 'B-grade' difficulty is not easy to achieve.

Predecessor, abandoned.

Wang Hao thinks that he can give it a try, and he is about to go to Abayun's R&D center to give a speech, and he must be facing a large number of algorithm engineers, and the content of the explanation is also related to the discrete Fourier transform algorithm, maybe he can get a lot of relevant inspiration?

……

It was the next day.

A direct flight from the West Sea to Hanghu took off and spent five hours before arriving at Hanghu International Airport.

Wang Hao walked off the plane with his luggage.

When he walked out of the airport, he saw a sign holding his name, and then walked over and asked, "Are you waiting for me?" ”

The person who came looked at Wang Hao, "Teacher Wang Hao? ”

Wang Hao nodded.

The person who came exhaled lightly and took the initiative to stretch out his hand, "I'm really sorry, I didn't expect you to be so young, my name is Zhang Bin, and I am here to pick you up." ”

"Let's go."

Zhang Bin drove Wang Hao to the hotel.

On the way, the two chatted.

Zhang Bin is not a full-time driver, but an algorithm engineer, the level of the company is still very high, and the manager of the technical department is at the same level, he is responsible for picking up Wang Hao, just hoping to have a common topic.

He was also full of praise for Wang Hao's achievements, "I read two papers carefully and studied them with my colleagues. ”

"We are very sure that this new method of building data models can greatly improve the efficiency and accuracy of data analysis."

"To be honest, I thought it would be an old professor, but I didn't expect it to be so young."

Wang Hao smiled.

The two talked all the way to the hotel first, and after putting the things away, they went to the R&D center.

Several people were waiting at the door.

Wang Hao felt the enthusiasm as soon as he got out of the car, and several people came around to shake hands and make introductions, among which the leader was Tang Jianfeng, the dean and direct person in charge of the R&D center, but the main exchange was Feng Youlai, the technical director.

Feng Youlai really deserves to be the 'technical director', and when he saw that Wang Hao didn't say a few words, he talked about what he didn't understand in the paper, and also talked to him about the areas where the new method could be used.

The former, however, is nothing.

After all, he is a doctor of mathematics, not a doctor of informatics, and at the same time, he has no relevant work experience and does not know much about applications.

Feng Youlai also discovered this problem, so he simply only talked about technical and algorithmic content.

Wang Hao was invited to the lounge, continued to chat with Feng Youlai for a while, and arranged to lie down and rest.

Five o'clock, dinner.

He went to the restaurant of the R&D center with the others, and after a brief meal, he went to a new hall to prepare.

When everything is ready, the time is almost up.

Wang Hao went to the podium in front of him, and just entered the arena and looked outside, and suddenly became a little nervous.

He is generally not nervous......

Now is a very special situation.

At a glance, it feels crowded, several times more than the students in the classroom.

The place where he was going was like a stage under the lights.

The scene is a bit like the scene of a large company's product launch conference, it should be the company's CEO or something, but he is just here to give an academic presentation......

It's an exaggeration!

When he slowly walked to the middle podium and looked down the stage, Wang Hao suddenly felt that he had lost a lot.

This kind of scene of academic report speech, the appearance fee is 200,000?

The price is going to be low!
