With the lecture experience of the Abayun Research Center, Wang Hao went to Penguin to give a similar lecture, and he was very well prepared.

Including the content of the explanation, the time and rhythm arrangement, I have carefully thought about it, and I have made PPT for it, and even the way of explaining has been pondered for a long time, and I am determined to tap the potential of all the attendees in order to maximize the sheep...... Ahem, I hope that more people will understand.

"After all, people also spend money, 300,000 is a lot, you must explain the content clearly!"

Wang Hao was thinking all the way.

According to past experience, the 'guided' method of explanation can bring more inspiration, but it is obviously not suitable for the explanation of difficult algorithms, the difficulty of 'Fourier-assisted construction of mathematical models' is slightly lower, and the difficulty of 'large number multiplication algorithm' is higher.

Even at the STACS conference, I didn't get much inspiration for doing the 'multiplication of large numbers'.

Wang Hao summed up the reason as 'too difficult'.

The difficulty is high, and it is not easy for the listeners to keep up with the train of thought, let alone diverge their thinking to think about other content, which brings a 'knowledge base' rather than a more important 'inspiration'.

"The guided explanation method is too slow, and the audience is not a student, so it is not suitable; It is certainly not good to give a report-style explanation, only providing knowledge content, and not increasing the inspiration value at all. ”

"The best way is to explain the basics, not to do proofs, but to explain the use of algorithms."

"That's probably what companies want to hear, right?"

Enterprises will definitely care about the correctness of the new algorithm, but whether the algorithm is correct or not is verified by academic institutions, and there is no need for enterprises to care at all, they are more concerned about the 'application of algorithms'.

'Algorithmic use' is the most important thing.

If you don't have to dig deep into the principle of the algorithm, just explain the application of the algorithm, the difficulty will be reduced linearly, and in the process of explaining, the content will be expanded step by step, which will definitely make the vast majority of people, even say, as long as there is a certain algorithm foundation, can keep up with the ideas.

Of course, there must be some elites who feel that the speed of explanation is slow, but they may diverge their thinking and bring more inspiration.

Wang Hao is full of expectations when he thinks about it.

……

After getting off the plane at Shencheng International Airport, Wang Hao saw the person who came to pick him up, and then went to the Penguin headquarters building, and his luggage was put into the hotel by the person who picked him up, but there was a lot of time left.

Penguin's core technical department is located in the headquarters building.

Wang Hao followed the reception staff to the technical department, and met Zhu Zhen, who invited him, and also met several technical directors, managers, etc., and greeted and introduced a lot, and it was not easy to remember the name.

Zhu Zhen and his entourage took Wang Hao to visit the technical department, and then went to the data center on the negative floor, and then found a reception room to rest, and lay on the soft sofa and squinted for a while.

Penguin's lectures are held at a similar time to the Abayun Research Center, with dinner at the conference hall at the back of the headquarters building, which has a large conference room.

Wang Hao made simple preparations, and the time was almost up, he calmly walked out from behind, and saw the uncountable heads in the conference hall, and his mood was much calmer.

Hundreds of people, normal operation.

Then Wang Hao stood on the podium, facing everyone in the audience, and when he noticed a few people in the front row, he suddenly sighed in his heart, "It's a big loss again!" ”

In the afternoon, the men met with each other.

One of them is Zhang Zhiwei, one of the real power giants of Penguin Group, who is fully responsible for Penguin's technology and data-related affairs, and can rank among the top five in the Penguin Group.

This kind of person, who not only has real power, but also has assets measured in hundreds of millions, actually sits in the audience and listens to his lectures, the key is that the lecture fee is only a pitiful 300,000......

It's shabby, isn't it?

With his disdain for the rich Chiguoguo, Wang Hao opened a lecture on 'Fourier transform-assisted construction of mathematical models', and after full preparation, he even calculated the time of each part of the content, and repeated some of the detours several times in a row, so that everyone could understand it.

As the explanation slowly unfolded and deepened, everyone in the venue became very serious.

Some employees with average ability think that it is difficult for them to keep up with the train of thought, but it sounds like they can keep up smoothly, and they suddenly become more serious.

At the same time, there are also some elites who feel that the speed of speaking is too slow, and they even have the heart to say a few words, which feels like returning to the student's classroom, where the teacher keeps repeating a problem that has already been understood, or explaining a topic that can be correct, and it feels like a waste of time to listen carefully, and if you don't listen carefully, you are afraid of missing the content behind.

Soon, an hour passed.

Wang Hao continued to speak without pause, as if he had fallen into the art of lecturing, until he found that the effect of the teaching coin was over, he stopped talking and hurriedly went to the side to drink saliva.

"Let's rest for five minutes before we continue!" He greeted the person in charge next to him, and also went to the side to rest for a while, and ate something to replenish his energy and strength.

Then, the lecture continued.

This lecture is more than an hour, and when the effect of the teaching coin is over, I simply use another teaching coin directly, and continue to explain after the time, and after another half an hour, I finally finished the final content.

Wang Hao finished the day, stood on the podium and exhaled lightly, looking at the total time of almost three hours.

Six o'clock, to nine o'clock.

This time it took longer than the Abayun Research Center to explain, but the obvious effect was also very good, most of the people were listening carefully, unlike the last time, some people obviously couldn't keep up with the rhythm, and it became meaningless to continue listening, so they simply didn't listen.

End of presentation.

After a 10-minute break, it's time for Q&A.

Some people raised application questions, and Wang Hao answered them one by one, because they were all application-level problems, and the process was explained in great detail, not like Abayun had so many questions that time, and it only took about half an hour to answer the questions, and it was over after saying a few key questions.

After the lecture ended, Wang Hao didn't have the energy to deal with the greetings, so he went back to the hotel to rest, closed his eyes and slept until the next day.

Work, continue.

The next day was relatively deserted, and the penguin did not organize a large number of people to listen to the lecture, but gathered dozens of elite experts to the small conference room to listen to Wang Hao's lecture on the 'multiplication algorithm of large numbers'.

Wang Hao still talks about 'applying methods', rather than 'proving the feasibility of new methods' like making a report.

The application method of "large number multiplication algorithm" is relatively much lower, just like ordinary vertical multiplication, if you want to use "addition" to prove that the calculation result of vertical multiplication is correct, it will definitely be more complicated, but only talk about how to do the calculation, there is no difficulty at all.

The same is true for the 'large number multiplication algorithm', which uses a fast Fourier transform combined with other methods to delineate the area, and then filter step by step to get the final result.

This process can be understood when you write it out.

Wang Hao is still very patient in explaining, which makes people feel that he hopes that through the lecture, everyone can really understand, understand, and even learn the new 'calculation method' directly.

Many people couldn't help but sigh, "This teacher Wang Hao is really serious and responsible for his work!" ”

"If it's someone else, it's estimated that I'll talk about it again, and if I don't understand it, I won't understand it, Mr. Wang Hao, I spoke well and seriously, and I repeated it several times in some places, for fear that someone wouldn't understand."

"Presumably he must be a good teacher respected by students in college!"

“……”

The explanation of the 'multiplication algorithm for large numbers' is much simpler, it only took more than an hour, and part of the time was to answer questions.

After the explanation, the lecture is over.

Wang Hao saw Zhang Zhiwei again.

Zhang Zhiwei was very busy with his work, and he didn't come to listen to the 'multiplication algorithm of large numbers', and he asked other people to explain the conference room in the middle of the explanation, and he knew that the effect of the explanation was very good.

Everyone was very satisfied with Wang Hao's explanation, so he invited Wang Hao to have lunch together.

Or a staff canteen.

Zhang Zhiwei and Wang Hao sat together and behaved very enthusiastically, but he didn't want to poach, because he knew that Wang Hao rejected Abayun and would definitely not come to Penguin, he just chatted casually with Wang Hao, talked about the technical problems of big data analysis, talked about market analysis problems, and so on.

Then they talked about the research.

In the eyes of large Internet enterprises, Wang Hao is a super algorithm expert, Fourier transform assists in the construction of mathematical models, coupled with the latest large number multiplication algorithm, both algorithm achievements are very shining, and he must be a top research talent in the field of algorithms.

Zhang Zhiwei is interested in Wang Hao's next step of research.

Wang Hao also said, "I'm studying the number of God, I should know this, right?" The third-order Rubik's Cube, the number of God, Ameriken has a team that uses a supercomputer to arrive at the number '20' using the brute-force method, but I want to use mathematical methods to prove it, not brute-force it. ”

Everyone next to him listened and nodded.

Zhang Zhiwei praised, "This research is very interesting, I also have some research on algorithms, if I am not mistaken, this should require a new algorithm, right?" ”

"Yes, I'm researching and already have an idea."

"Did you apply for the program?"

Wang Hao shook his head, "I originally wanted to apply for a Youqing, but the review time was too long, and I couldn't wait." ”

"So be it!"

Zhang Zhiwei said with a smile, "We can sponsor and give you financial support." ”

"Collaborative R&D?" Wang Hao thought about it for a while, but he still didn't understand, "But there is no patent for the research of this basic algorithm?" ”

Zhang Zhiwei smiled heartily and said, "We don't want patents, we just want to support basic research and development, Mr. Wang Hao, you don't have to push, we don't want anything, just sponsorship." ”

"Uh~~"

Wang Hao thought for a while, and there was no reason to refuse.

How good is it for a company to sponsor its own projects, but not to give money directly?

It's like giving money to yourself.
