Chapter 116 The Privileges of Celebrities and the Invitation from the Aeronautical Materials Institute
After listening to what Wang Hao said, Zhang Zhiqiang stared at him for a long time and took a deep breath, but he had no idea what to express.
He silently returned to his seat.
After lighting up the computer screen, I typed four words on the search page - be at peace with the situation.
The explanation on the search page is, 'No matter what environment you are in, you can be at ease and content.'
Zhang Zhiqiang thought carefully about literary issues, "This word is used to solve research problems, which means not to take the initiative to think about it. When you encounter a special opportunity and think of a problem, just think about it. It doesn't matter whether you solve the problem or not."
.”
"So, this process will take a year or two, at least a few months? No matter how little, it will take ten days and a half, right?"
"Before class, I said I would just take things as they come, but after class I figured it out..."
Zhu Ping walked over silently and stared at Zhang Zhiqiang's screen, seeming to fully understand his feelings, and even put a hand on his shoulder.
Zhang Zhiqiang looked back with a sad face.
The two looked at each other and sighed in unison, "Alas!"
After Zhang Zhiqiang finished lamenting, when he looked at Luo Dayong's expression, there was no longer any "angry" expression, but his eyes were full of envy and jealousy.
That is a graph isomorphism problem, one of the NP problems!
The NP-complete problem, also known as "NP=P?", is one of the seven major mathematical conjectures of the millennium, and is the number one super difficult problem.
This issue is very complex.
P problems are easy to understand. They are problems with certain calculations. For example, addition, subtraction, multiplication and division can be deduced according to formulas, and the results can be obtained by calculation.
However, some problems cannot be calculated step by step.
For example, when looking for a large prime number, there is no formula that can deduce the next large prime number step by step.
The answer to this kind of question cannot be calculated, and the result can only be obtained through indirect 'guessing'.
For example, 7 is a prime number, which one is the next prime number? You can check 8, 9, and 10. None of them are prime numbers. Check 11 and find the prime number.
This is a non-deterministic problem. The result cannot be obtained through calculation, but needs to be verified one by one.
This kind of problem that uses the exhaustive method to get the answer is a complete polynomial problem. If you test it one by one, you can get the final result.
However, the complexity of such an algorithm is exponential. When the number reaches a certain level, the calculation will soon become impossible.
Some scientists have discovered that similar complete polynomial non-deterministic problems can be converted into a type of logical operation problems called 'satisfaction problems'.
Since all possible answers to this type of problem can be calculated in polynomial time, is there a deterministic algorithm for this type of problem that can directly calculate or search for the correct answer in polynomial time?
This is the famous "NP=P?" conjecture.
The above example of finding prime numbers is just the simplest NP problem.
In fact, NP problems cover a very large area and are an important direction of complexity theory. The "graph isomorphism problem" studied by Luo Dayong is one of the classic NP problems.
"Graph isomorphism problem" refers to the comparative calculation of complex networks.
For example, there are eight points on each side, and the point distribution is different. Each of the eight points is connected to at least one other point.
Because the distribution of points is different and the connections of each point are consistent, the drawn graphics will be very different.
So how to prove that the two graphics are completely consistent?
This is the graph isomorphism problem, which proves the consistency of two complex networks.
Luo Dayong had been researching for several years before, and had already found the direction and thought of a solution. What was missing was a 'flash of inspiration'.
Many studies will be limited to ‘this one foot’.
Some people are lucky and solve the problem suddenly when they think of it. Some people are unlucky and can't overcome it in their lifetime.
Wang Hao took a class and got some inspiration. He found a "way to take the first step."
After returning to the office in the complex building, Wang Hao began to talk to Luo Dayong. Even if it was a very important research, they did not find a private environment.
Mainly because of confidence.
The first self-confidence is that the people in the office are of good character and will not do anything to steal results or publish things in advance.
Second, it is impossible for anyone, including Zhang Zhiqiang, to understand the content.
Perhaps because the course he was teaching was "Nonlinear Functional Analysis", the method Wang Hao found was to start with the analysis of the entire system.
Starting from the analysis of the entire system, we slowly connected to each point, and then connected to Luo Dayong's research.
It sounds simple, but is actually very complicated.
Luo Dayong's level is quite good. Wang Hao only talked about the beginning, and he seemed to understand it a little. After listening to a short paragraph later, his eyes were already shining brightly.
"I see!"
"So it's so simple! Wang Hao, you are really a genius, such a genius. This method is so ingenious."
"I've never thought about it in this direction before."
Luo Dayong hugged Wang Hao excitedly. He noticed Wang Hao's indifference and said excitedly, "Maybe it's nothing to you, but to me, this is the result of several years."
"Thank you, Wang Hao!"
"Thank you!"
"We did this research together, and the credit for the results also belongs to you!"
Luo Dayong cried excitedly.
It is said that "a man never sheds tears". When you are determined to complete a result, especially when you see the results of several years of hard work, the excitement is something that others cannot experience.
So Wang Hao's expression was very indifferent. He was also happy for Luo Dayong in his heart, but he couldn't get excited at all. All he did was listen to Luo Dayong talk about his research. After understanding it, he went to a class and found the last word.
inspiration.
Zhang Zhiqiang and Zhu Ping were also very indifferent. They were also happy for Luo Dayong, but they couldn't help but think of Luo Dayong's words just now, "It turns out it's so simple."
Simple?
Zhang Zhiqiang just leaned over and listened a few times, and found that a lot of the content was beyond the scope of his knowledge.
Simple peat!
Needless to say, Zhu Ping didn't even move her steps, knowing that she couldn't understand.
Simple……
If anyone says this research is simple, I will go over and pull his hair out right away!
Zhu Ping stared at Luo Dayong's hair and suddenly felt her hands itching.
…
Luo Dayong's research has been completed. All that remains is to summarize the content, give a report at a mathematics conference, or write a paper for publication.
The news spread quickly.
Many people in the school came to visit after hearing about it. Several professors, directors and the like made a special trip to give Luo Dayong some advice.
For example, what academic conferences should I attend, what journals should I submit to, what is the format of the paper, etc.
Zhu Jianrong came here.
Chen Qinghua, the dean of the School of Computer Science, also made a special trip to talk to Luo Dayong for a long time to confirm that he had completed his research, and then said some words of encouragement.
The office in the complex is busy, with people coming and going all the time.
Wang Hao looked at the professors, directors, and leaders one by one, and felt a little bit like they were making a mountain out of a molehill. Even if they completed a large research, it wouldn't be like this, right?
When he saw that the school's vice-principal had made a special trip to encourage Luo Dayong, Wang Hao said to Zhang Zhiqiang with a corner of his lips, "Isn't this a bit exaggerated?"
Zhang Zhiqiang’s reaction was quite bland.
He looked at Luo Dayong with envy, then turned his head and said, "It's not an exaggeration at all."
"This is the correct way to achieve great results."
He nodded vigorously as he spoke, showing his absolute persistence in his opinion, "It's abnormal for you to publish a paper silently."
Zhu Ping and Yan Jing also came over and agreed with Zhang Zhiqiang's words, "That's right."
Yan Jing nodded, "That's true."
"……All right!"
Wang Hao found himself standing on the opposite side of the office and gave Luo Dayong a thumbs up, "You are great!"
…
Luo Dayong's results made a big fuss, but in fact, Wang Hao was also responsible for the results. He insisted on co-authoring Wang Hao. If that didn't work, Wang Hao would be the corresponding author.
Wang Hao still agreed.
Although most of the research was done by Luo Dayong, he was the one who kicked the key.
In addition, it is also beneficial to have his name on the paper.
For example, submitting an article.
Some professors, directors, etc. in the school gave Luo Dayong some suggestions. Some said that he should attend academic conferences to give reports, and some said that he should submit articles to top magazines. Wang Hao did not need any advice at all, "You can directly submit your article to "New Mathematics".
"Progress", the corresponding author writes my name, and I will say hello over there."
This is the ‘celebrity’ privilege.
"New Advances in Mathematics" has published two papers by Wang Hao, including "Boundedness Argument for the Existence of Ating Constant" and "Conjecture on Determining Function of Mersenne Prime Numbers".
After two cooperations, Wang Hao got to know the review editor. He could quickly review the paper just by saying hello. Because the paper itself is of high value, it will be published very quickly after review.
This eliminates the possibility of submissions being brushed down for no apparent reason.
Some top international academic journals are like this.
When I see top-level research contributions submitted by unknown people, I just browse them without reading the content, because there are many similar submissions, most of which are wrong arguments. If you read them carefully one by one, it is a waste of time and money.
energy.
Add his name to the author of the paper, and then notify the editor and reviewer of "New Advances in Mathematics". As long as there are no major problems, you can wait for publication.
As for work such as writing papers, Luo Dayong is entirely responsible for it.
Wang Hao is not very interested in this research. Complexity theory is Luo Dayong's research field, and his area of focus is analytic number theory.
It's already the end of the semester.
There was still a lot of work to do at the end of the semester, such as registering for courses for the next semester. Wang Hao made a special trip to the School of Science and confirmed two courses.
One is a refresher course on "Probability Theory and Mathematical Statistics".
Many undergraduates would fail their courses, and there would be retakes in the next semester if there were no regular classes. Wang Hao decided to help the senior professors share the teaching pressure, so he directly took over a retakes course.
There is no need to prepare lesson plans for the same course, which makes teaching a little easier.
Another course is "Algebraic Geometry" in the first year of graduate school, which is a basic course for a master's degree and a professional course for a doctoral degree.
This course is based on abstract algebra and complex analysis, and is relatively difficult.
The remaining elective courses can be considered later and do not need to be submitted in advance.
In addition to reporting courses, Wang Hao also participated in the invigilation work. After all the exams were completed, he started grading papers, entering scores, etc.
These complex tasks take a lot of time.
After everything is over, time has entered the winter vacation. Students and teachers have all entered the holiday. Whether it is on TV, in the streets, etc., there is a bit of a Spring Festival atmosphere.
The Spring Festival is the most important festival for Chinese people.
Wang Hao also booked a flight and returned home. He was still very busy when he returned home, but he was not doing anything related to research and development. Instead, he started buying a car and a house as planned.
It only took three days to spend one million generously.
He had previously remitted more than 200,000 yuan to his family, but Wang Haiqing had been reluctant to buy a new car, so Wang Hao simply bought it. A family car worth more than 100,000 yuan was not expensive.
The biggest expense is buying a house.
He bought a large square meter in a new community next to the park. He also hopes that his parents' living environment will be better. As for whether to move there, it depends on their own wishes.
After throwing away a million, Wang Hao felt more relaxed at home, at least he didn't always hear words like 'girlfriend' and 'marriage'.
He is not very old, only over 25 years old now, but in the eyes of his parents, they always hope that after their children have a stable job, it is best to get married and have children as soon as possible.
Wang Hao's scalp felt numb just thinking about it.
marry?
Do not make jokes!
Of course, the great youth of more than 20 years should be dedicated to the cause of science. How can it be wasted on women?
No, absolutely not!
Instead, it's about falling in love and not getting married...ahem...
…
After the holidays.
Wang Hao returned to Xihai University first, and then found that he had received various invitations.
The news that he was going to give a report at Shuimu University has been announced. As a result, two universities in the capital invited him to be a guest, and there was also a very special invitation from the Institute of Aeronautical Materials.
It's Cao Dongming.
Cao Dongming invited him to visit the Institute of Aeronautical Materials, the aviation equipment base, and also invited him to give a report at the Institute of Materials. There were several signatures on the invitation letter, including two academicians.
As for visiting the Aviation Materials Institute and the Aviation Equipment Base, Wang Hao is not very interested, but he is giving a report...
He thought he could go.
After seeing the inspiration value data of 'Task 3', he became more interested.
【Task 3】
[Research project content: Research on step-by-step probability of prime numbers (difficulty: S).]
[Inspiration value: 64.]
Although the related fields of data mining are not closely related to the study of prime numbers, the knowledge content in other fields may also bring additional inspiration.
This is hard to say.
"It's better to go there. Anyway, it's just a trip to the capital. It means going to one place or two places."
