An Expert Is actually By My Side

Chapter 108 The Undisputed Choice! (44)

Perhaps it was because there was no Hope Cup in the previous life. Hao Yun felt his conscience and said that he really didn't feel much about this trophy. Even the initial registration was decided under the lure of Dean Li Guoping.

However……

He always felt that he who said that sentence seemed to be misunderstood.

After the interview, Hao Yun always felt that something was wrong, so he explained his thoughts to Dean Li Guoping, hoping that he could help clarify with the TV station.

However, he didn't expect that the old guy didn't intend to listen at all, so he waved his hands and said comfortingly.

"Don't pay too much attention to it. It's not a big problem. What's more, when I look back, I think what you said is quite right. There is really no need to pay too much attention to a mere Hope Cup. Isn't that something you can do with your hands? Our Jiang University There are a lot of talents, you should stand up straight when you walk outside, and you can't be looked down upon by the boys from Charcot University next to you!"

"What does this have to do with Charcot University?" Hao Yun said dumbfounded.

"What's the matter? Heh," Dean Li Guoping snorted coldly, his tone was not salty, but the corners of his mouth could not hide the joy of revenge, "When they won the championship last year, they didn't forget to run on us. .”

Good guy.

Another Scorpio.

Hao Yun sighed inwardly, dumbfounded, and decided not to dwell on this matter anymore...

...

The week after the Cup of Hope final.

Shanghai City, the conference room of Xiadong Normal University.

The meeting of the expert group has reached the third round.

Yang Fengyuan, a member of the School of Computer Science at Xiadong Normal University, has made new progress in his research.

"It's a very interesting phenomenon. A few days ago, I used a supercomputer to try the reciprocal square root algorithm using the traversal method. As a result, the best value obtained after 140 million calculations was 0x5f37642f."

"I thought this result would be closer to the accuracy than the 0x5f375a86 proposed by contestant No. 101—that is, the 'magic number', but the result brought into the Newton iterative algorithm was beyond my expectations... I obtained it through supercomputing traversal The result is actually slightly worse in accuracy?"

Speaking of this, Yang Feng said in a low voice with a look of seeing a ghost on his face.

"Although this situation is not completely impossible, after all, the possibilities we are facing are infinite. But he actually found a hexadecimal number that is more reliable than a supercomputer in an hour... If this is a coincidence, That's too damned."

While it would probably be more hellish if not a coincidence, at least it would be a little more convincing.

Another expert in number theory, Professor Jia Yuxin from the Xiaguo Mathematics Research Institute, suddenly spoke.

"0x5f37642f? Wait a minute, the result I calculated is the same as yours, but I didn't use supercomputing to calculate it, but a method of linear approximation to get the optimal value... purely mathematical method."

Scholar Yang Fengyuan: "...pure mathematical method?"

"That's right," Professor Jia Yuxin smiled bitterly, with the same expression of having seen a ghost, "Theoretically, my method should be quite reliable, although there are still many things that are difficult to explain. Afterwards, I will bring 0x5f37642f However, no matter how to execute the Newton iterative algorithm, the result of obtaining the exact value is a little worse than the result obtained by the 'magic number'... I was very surprised at the time."

"Can I watch the process?" Academician Zhan Yongshu asked hastily.

Although he is not a professional mathematics expert, information engineering also requires a mathematical foundation after all, so there is no problem in understanding it.

Professor Jia Yuxin nodded, took out a thick stack of documents from the document bag he carried with him, handed it to the assistant who came to the meeting with him, and signaled him to send it on.

"Of course, I'm about to send my research results to everyone! I can definitely say that these results are very interesting... I even forgot to eat dinner yesterday."

After receiving a stack of papers, Professor Zhang Cunhao couldn't help but say the title when he saw the title before he could look at the specific content.

"...was the original constant derived mathematically or by trial and error? What is it?"

"Of course it's the title of the paper. By the way, this is the latest paper I wrote..." At this point, Professor Jia Yuxin also smiled embarrassedly, and continued, "Of course, it hasn't been published yet, just for everyone to see .”

After all, the results of the competition have not yet come out, and papers written based on such unpublished results are obviously not suitable for publication, otherwise it will be plagiarism.

However, if it is not published publicly, there is no problem in circulating it privately within the scope of those who know.

As for why this paper was written in advance and brought to this conference table, on the one hand, it was because I couldn’t help itching to see this interesting topic, and on the other hand, it was because I was afraid that these colleagues would be the first.

Sure enough, he got at least three blank stares just halfway through his words.

But after seeing these three blank eyes, the smiling Professor Jia felt relieved.

Academician Zhan Yongshu didn't think so much. At his age and status, he doesn't need to publish papers to maintain his academic status. It is precisely because of this that he has shifted his focus to education in the past two years.

After reading the paper, Academician Zhan frowned slightly and continued.

"It's really interesting...although it still doesn't explain how that number came about."

The experts sitting at the conference table also nodded.

Are the original constants derived mathematically or by trial and error?

Professor Jia Yuxin's thesis is at most an introduction. It is a good beginning for a research topic, but it is still far from the end.

"Three rounds of conferences have no results. I am afraid it will be difficult to solve this problem in a short period of time." After reading the paper, scholar Yang Fengyuan sighed softly. .”

Hearing this sentence, Academician Zhan Yongshu nodded in agreement.

Indeed, as Academician Yang said, the conference room gathered the most knowledgeable minds in the fields of mathematics and informatics. Although they are not necessarily the smartest, they must be experienced.

However, even so, after holding three rounds of meetings, they did not find a suitable explanation to explain how the number was calculated, which only shows that this issue should not be discussed in the conference room, but It is a research topic that should be pondered over and over again in the laboratory.

I believe that as long as there is enough time, they will be able to find the answer.

"I agree with Academician Yang's point of view. The discussion on 0x5f375a86 will stop here."

After a pause, Academician Zhan Yongshu stood up and continued with a serious tone.

"Gentlemen, we must now consider a more serious matter."

"That is about the champion of this Hope Cup."

It has been a week since the competition, and all the works have been reviewed by the main test committee

Even if there is controversy now, the focus of the controversy is on how the number came about, not on the value of the magic number itself.

There was a moment of silence in the conference room.

"I will vote for contestant No. 101. Whether it is based on subjective opinions or objective evaluations, the answers he submitted are excellent."

"Second! Although his answer is very simple, the art of informatics is to simplify and spread complex problems."

"I also agree with this point of view. At least so far, I have not seen any more eye-catching works than this number."

Professor Zhang Cunhao didn't speak, and seemed to be hesitating about his choice.

Scholar Yang Feng didn't express any opinion either, as if he felt that there was no need to discuss this issue at all, he just wrote his choice on the voting card, then got up and left the meeting room.

Looking at the situation in the meeting room, Academician Zhan Yongshu smiled and nodded.

"It seems that everyone's opinions are unexpectedly consistent."

The championship seems to be no suspense at all, and this is just as he expected.

The Hope Cup has been held for so many sessions, and he has been the chief test committee member for so many years, and this is the first time he has seen which answer makes the entire chief test committee helpless.

If such an answer is not worthy of the glory of the championship.

That was simply a loss for the Cup of Hope!
