Wang Hao dragged himself up from his laziness and tried hard to return his life to a normal rhythm.
Run, exercise.
After running around the school playground for about six times, I felt my steps were a little heavy, so I picked up my coat and walked towards the restaurant.
On the way, I met Professor Wang Huanxin who came for a walk.
Older people always like to walk in the morning and evening, and Wang Huanxin is the same. Walking around the school every morning, breathing fresh air and doing simple exercises can also make him feel better.
"It's Wang Hao!"
Wang Huanxin turned around and said hello to Wang Hao, and the two walked forward together.
Wang Huanxin has been in a good mood recently. He was specially promoted to a full professor because of his teaching expertise, and he got rid of the embarrassment of being just an associate professor at the age when he is about to retire.
As he walked, he talked to Wang Hao, "Your research some time ago was amazing. Arting's conjecture, Arting's constant, many people dare not touch."
"I have always thought that you attach great importance to teaching, but I didn't expect that you are also very strong in research and development. It's amazing. It's amazing."
"Thank you." Wang Hao expressed his thanks politely.
"This is not polite, this is telling the truth." Wang Huanxin sighed and shook his head, "I can't do it. I have known since I was young that my talent is limited and I cannot go far on the road of mathematics."
While Wang Huanxin was talking, he asked casually, "What research are you doing recently?"
"Messenne primes." Wang Hao simply said four words.
Wang Huanxin was stunned after hearing this, and said with a wry smile, "Mathematics is that the simpler it is, the more difficult it is. Mersenne prime numbers, this is not a field that ordinary people can touch."
He suddenly said, "Speaking of Mersenne prime numbers, I seem to have seen a report this morning, saying that a new Mersenne prime number was discovered, or was it discovered by a Chinese volunteer named Wang... Hao?"
Wang Huanxin glanced at Wang Hao and suspected that his memory was not good. He immediately took out his mobile phone and put on his reading glasses to look at it carefully. After a long time, he smiled and said, "It's really Wang Hao. The name is the same as yours. You said this?"
Is it a coincidence?"
"Yeah?"
Wang Hao was also very curious, so he went over and took a closer look. It was a report quoting an English announcement, saying that Mersenne primes had been discovered, and it came from Chinese volunteers...
WangHao?
"What a coincidence..." Wang Hao said as he felt something was wrong.
At this time, the mobile phone rang.
It's Zhang Zhiqiang.
After pressing the answer button, I heard Zhang Zhiqiang's excited shout from the opposite side, "Wang Hao, come to the laboratory, come to the laboratory! Big discovery! Big discovery!"
"coming."
Wang Hao nodded to Wang Huanxin in agreement, and then quickly went to the computer laboratory building.
Wang Huanxin looked at his back in confusion, thought about it carefully, and opened his mouth wide, "Isn't this...impossible?"
"Is there such a coincidence?"
…
The sixth floor of the computer laboratory building is the central laboratory.
Zhang Zhiqiang pointed at the computer screen and said excitedly, "Look! I saw it when I came here. A new Mersenne prime number was detected."
"I looked at the record, and I just checked the second number of 'File 1', which happened to be a Mersenne prime number!"
"The GIMPS official website has released the news, take a look! The new Mersenne prime number was discovered by Wang Hao, a volunteer from China!"
Zhang Zhiqiang kept talking excitedly.
In fact, he didn't have much confidence in finding Mersenne primes. He just thought that he should get involved. It was a research test with an opportunity. He never expected that the program would be able to successfully find Mersenne primes on the first night it was run.
This is an exciting enough result.
Anyone can participate in the search for Mersenne primes. The GIMPS announcement only refers to "volunteers". Those who find Mersenne primes are probably not scholars. For example, among GIMPS participants, there are dentists, couriers and other professions who have found Mersenne primes.
However, every time a new Mersenne prime appears, it still attracts international attention, and there will be many reports in China.
The Academy of Sciences, the Science Foundation, the mathematics institutes of major universities and professional academic media will all report the news.
In addition, the emergence of new Mersenne primes will also usher in a wave of ‘popular science’.
In some elementary and middle school test questions, there may be examples of the discovery of Mersenne prime numbers. Considering that the discoverer of the new Mersenne prime numbers is Chinese, the examples may also have names.
Although the research was completed by Wang Hao, he also helped type the core code and found other people to help. Not only could he get some results, bonuses, etc., but it would also be nice to have his name mentioned when reporting.
.
Wang Hao was also a little surprised. He was still aware of his research.
Because he did not fully study the rules of Mersenne prime numbers, the judgment conditions he made were not accurate, but the probability of being a Mersenne prime number was greater.
File 1 contains twenty-six numbers, and the highest probability of determination is less than 6%.
The judgment probability of the second number is 3.98%. Compared with other Mersenne primes that have been discovered, the judgment probability is relatively smaller.
Is the result really a Mersenne prime?
"What a good luck!" Wang Hao couldn't help but sigh. If he did a prime analysis on all the numbers, it would not be surprising to see a Mersenne prime number among them. If only the second one appeared, luck would have played a big role.
Element.
"I just wanted to give it a try at first. From the looks of it, the analysis still needs to continue." Wang Hao said after calming down.
"Of course we have to keep going. What if another one is discovered?" Zhang Zhiqiang's heart was filled with beautiful longings. "Having one is already great, but if another one is discovered, you will become the first person to have Mersenne prime numbers."
While the two were talking, several doctoral students and graduate students came over.
They chattered, "Did you see the news? A volunteer named Wang Hao found a new Mersenne prime number."
"I feel that this Wang Hao is Teacher Wang Hao, otherwise there would be no such coincidence."
"Hurry up, it might be!"
They confirmed the news when they arrived at the entrance of the central laboratory.
Zhang Zhiqiang shouted with excitement, "Our research results are here. We have found the Mersenne primes. I told you all to join in, right?"
"It really is!"
"This is so amazing, I found it in one day!"
"Teacher Wang Hao, have you cracked the mystery of Mersenne prime numbers?"
This question was very important, and everyone else looked at it.
Wang Hao shook his head and said, "That's not true. I feel that even if the Mersenne prime numbers are regular, it is difficult to express them. The method I used to determine is just to compare the existing Mersenne prime numbers and make a probability determination."
Everyone else nodded in understanding, but they were still excited, "That's amazing too, being able to determine the probability of Mersenne numbers."
"Will this help me find the next one?"
"I found a number worth 100,000 U.S. dollars. If it exceeds 100 million digits, it's worth 150,000 U.S. dollars. I think we can find a few more..."
"That makes sense!"
Several doctoral students and graduate students began to look at Qian.
Wang Hao smiled and shook his head and said, "Don't think too much. You are lucky enough to find one. It is very difficult to find the second one."
"Just in time, you are here."
As he said this, he took out a large wad of cash from his bag, which he had prepared yesterday, and simply gave fifteen hundred-dollar bills to each student. "The extra five hundred dollars will be used as a bonus."
Some students declined a few times and then accepted.
Now that a new Mersenne prime number has been found, even if it is just to celebrate, as a participant in the study, it does not matter if they take an extra five hundred dollars.
…
In the morning, reports began to ferment.
The morning report only quoted the GIMPS announcement, but as more people saw the news, there were naturally more reports.
However, when the media reported it, they did not know which specific 'Wang Hao' found the Mersenne prime number. They just reported that it was 'Chinese volunteer Wang Hao'.
Wang Hao, this name is too popular. Some people thought of Wang Hao from Xihai University and thought it couldn't be such a coincidence.
There are a lot of media reports, but the reports are almost in the same format. First, they explain that a new Mersenne prime number has been found, and then they say it is from domestic GIMPS enthusiasts.
What follows is an introduction to what Mersenne primes are, what distributed computing is, and the history of discovering Mersenne speed, etc.
While the media continued to report, the central laboratory became more and more lively. People who knew that Wang Hao and Zhang Zhiqiang were studying "finding Mersenne primes" immediately came over after seeing the report.
Including Chen Qinghua, including Qi Xiao, and others in the School of Information.
Even Li Ming.
Li Ming came to the computer laboratory to look for Wang Hao that day. He seemed to remember saying something about Mersenne prime numbers. He came over to take a look when he saw the news. Unexpectedly, it was Wang Hao who found the Mersenne prime numbers.
Several people who came were very shocked.
No matter Chen Qinghua, Qi Xiao or Li Ming, when they heard "finding Mersenne primes", they all thought it was a fantasy. They didn't expect that they would actually find it after only a few days.
A group of people gathered in the corridor and kept talking, "I saw this message this morning and immediately thought of Wang Hao. I didn't expect it to be true."
"How did you find this? It's amazing!"
"Wang Hao, have you cracked the mystery of the Mersenne primes? Otherwise, how could you have found the Mersenne primes so easily?"
Wang Hao was surrounded by a group of people and kept asking questions, so he could only repeat it again, "I just made a judgment comparing other Mersenne primes. It was really lucky."
"Sometimes, luck is also important!"
Li Ming nodded vigorously and asked, "Please explain the situation in detail. I will go back quickly and make an announcement in the school. This matter needs to be publicized so that they know that our mathematics research and computer research at Xihai University are all
It is very powerful.”
Mathematics Research, Wang Hao.
Computer research means writing code together and using computer experiment equipment.
Of course, school promotions are not so clear-cut. Whether it is mathematics or computers, they are both good publicity for the school.
In fact, finding the Mersenne prime itself may seem like good luck to the outside world, but Wang Hao is the first Chinese to find the Mersenne prime, and he is also a mathematician, algorithm expert, and scholar.
This achievement definitely deserves a good publicity.
After Wang Hao gave a brief explanation, Li Ming immediately went back to write a news announcement, revised it with several people from the Science and Technology Office, and then released the announcement--
Congratulations to Professor Wang Hao from our school for finding a new Mersenne prime number.
With the help of Professor Zhang Zhiqiang and other students, Professor Wang Hao relied on his own research on Mersenne prime numbers. After nearly a week of hard work, he finally discovered a brand new Mersenne prime number using the computer in the computer laboratory.
M6XXXXXXX, the new Mersenne prime number...The following is the popular science of Mersenne prime number.
After Xihai University’s announcement was released, it was immediately forwarded by various media and quickly became a hot search list on the Internet.
Netizens who saw the news about the university announcement were very surprised to find out that the so-called "Chinese volunteer Wang Hao" who discovered the Mersenne prime number was Professor Wang Hao of Xihai University.
"Professor Wang Hao is so lucky!"
"I remember seeing it a few days ago, saying that he was studying Mersenne primes. Some people said it was a waste of talent, but now he has found a new Mersenne prime?"
"You may not have noticed the key. The announcement said that Wang Hao found the Mersenne primes in just a few days."
"I have been participating in GIMPS for several years. It is too difficult to calculate a number now. I assigned a number two months ago and I hang up for more than four hours every day. I haven't finished the calculation yet."
"Even if the computer he uses is better and has full power, he probably only counts two or three numbers? What kind of character is this?"
"Listening to what you said, this announcement from Xihai University is too Versailles, isn't it? After counting a few days, he is still 'working hard'. What is he working hard for?"
As for the "relying on my own research on Mersenne prime numbers" at the beginning of the announcement, it has been ignored by most people.
Mersenne prime?
Research?
If the pattern of Mersenne prime numbers can be found, it will not be a Mersenne prime number discovered, but a set of Mersenne prime numbers.
…
While media reports continued to ferment, Wang Hao finally sent away the "onlookers" and went to the small office next to the central laboratory to start research with peace of mind.
It is indeed not easy, or even impossible, to find a definite rule for Mersenne prime numbers.
Wang Hao’s research content is ‘Checking Algorithm for Mersenne Prime Numbers’. When he wanted to try to do ‘probability analysis that the Mersenne number corresponding to the exponent P is a Mersenne prime number’, the inspiration value of ‘Task 2’ was only a few 70 points.
Later, I wrote code with Zhang Zhiqiang and the students, and in the process of constructing the entire algorithm, the inspiration value continued to increase, faster than the growth rate of teaching.
"It seems that leading the team to do projects and do research together will also help increase the inspiration value." Wang Hao had a new understanding of the mission inspiration value, and when he checked the mission system again, he couldn't help but smile.
【Task 2】
[Research Project Name: New Mersenne Prime Testing Algorithm (Difficulty: A).]
[Inspiration value: 101 points.]
Got it!
He immediately used 100 points of inspiration, the knowledge and inspiration in his mind to quickly form a complete path.
Then, he felt a little surprised.
"The results of algorithm research are actually mathematical? But that's right. It must be related to the law of Mersenne prime numbers. Otherwise, it would be impossible to make a judgment based on the exponent P."
