Dean's Office of the Faculty of Mathematics!

Dean Xiao smiled: "Ye Fei, what do you think of this condition?" I don't think any university can offer this condition, Fudan's two million house purchase subsidy is indeed very high, but that is the magic capital, two million people want to buy a house in the magic capital, far from enough. ”

"But with a subsidy of one million to buy a house, you can buy a very good house in the dunes."

Ye Fei nodded and said, "Yes!" ”

Other universities have an annual salary of between 200,000 and 300,000 yuan, and there is no housing subsidy.

Although Ye Fei is not bad for this money, money shows attitude.

And the most important thing is that as an alma mater, as long as the conditions are good enough, Ye Fei is willing to stay.

"And we're going to sign the contract?" Dean Xiao said happily.

"Hmm!" Ye Fei nodded.

It is more troublesome to sign a contract for a university teacher.

Ye Fei is a regular worker, there is a establishment, and he needs a political examination, a physical examination, a copy of his academic certificate and a copy of his ID card, and then he has to report it.

The establishment is a turnip and a pit, and it is a quota every year, and even in universities, there is not much establishment.

But fortunately, each college of Zhonghu University has a few establishment places every year.

After joining the editor, unless Ye Fei does something angry, he will not be dismissed from the university in this life, and he can receive a salary every month.

June 1, 2023!

In the school playground, many students sat on stools and watched the principal in the red principal's uniform speak on the stage.

Graduation ceremonies are taking place here.

"Good morning, today is a big holiday for you......"

"Next, Ye Fei, a doctoral graduate of the School of Mathematics, will speak on stage as a student representative."

With warm applause, Ye Fei wore a black doctor's uniform and walked to the stage.

Everyone looked at Ye Fei's green face, and their hearts were full of emotion.

They are all twenty-seven or eighteen years old, some are around thirty years old, and Ye Fei is only twenty-three years old.

Graduating with a Ph.D. at the age of twenty-three is very rare.

Ye Fei came to the stage to shake hands with the principal, then walked to the podium and said, "Dear alma mater leaders, teachers, dear students, good morning!" ”

"Six years ago, I came to Zhonghu University ......"

After the graduation ceremony, Ye Fei returned to the dormitory.

Watching the three roommates all stare at him.

"What's wrong?" Ye Fei said with a smile.

"Hey......" Zhuang Nan said: "I really didn't expect that you would graduate in a blink of an eye." ”

"yes!" Zhou Lin shook his head and said, "I thought we would stay together for three years, but I didn't expect that you only stayed for two years and left." ”

Master's degrees are divided into professional master's and academic master's.

A two-year program is generally a professional master's degree, and a three-year program is generally an academic master's degree.

Basic Mathematics, all academic master's, no professional master's.

Xu Tiandao: "Others complete a master's degree in two years, but you complete a master's degree and a doctorate in two years." ”

The other two nodded, which was really heartbreaking.

"Who said I left?" Ye Fei smiled: "Didn't I stay in school to teach, we will meet again in the future." ”

The three of them lowered their heads silently, feeling as if their hearts had been pricked.

There are a total of 39 985 universities in the country, and they are all very good people who can be teachers in 985 universities.

The students who were retained to teach at 985 University were also cattle during their school years.

It may be that they have been with Ye Fei for a long time and don't feel much.

But now I deeply feel the gap between the scumbag and the god.

"When are you going to move out?" Zhou Lin asked.

Ye Fei has graduated, so he can't live in the dormitory.

Ye Fei said: "In two days, pack up your things and move to the nearby teacher's bachelor apartment."

There is a community built by the school near Zhonghu University, and there are single apartments for rent to the employees of the university.

"We'll help you then." Zhuangnan Road.

He and Ye Fei have the deepest relationship, the two of them are in the same class as undergraduates, and they are under the same tutor in graduate school.

He was very reluctant to let Ye Fei leave.

Although Ye Fei and Ye Fei can still meet often at school in the future, they don't live together after all, and they meet much less often than before.

Supercomputing Center, 111 Base No. 1 Laboratory!

Ye Fei looked at the numbers on the paper and said, "The language class P and NP ...... that are acceptable in polynomial time"

After thinking for a long time, Ye Fei wrote it down on paper.

[Let A⊆B, where B is a class ...... composed of infinite sets]

After a while, Ye Fei nodded and said, "Try it!" ”

With that, he sat down in front of the computer and added the mathematical formula to the algorithm.

When the input was completed, suddenly, he was surprised to see that the original computing power of 500 million accelerated and increased, and finally stopped at 5 billion computing power.

"This ......" Ye Fei said in astonishment: "It has improved so much?" ”

The P and NP problem has always been a problem that mathematicians and computer scientists have worked.

Ye Fei had a whim today to solve some of the P and NP problems.

Combined with mathematical algorithms.

"But why is it going to be improved so much?" Ye Fei was puzzled.

Although he created the mathematical algorithm, and he also solved the N and NP problems, why did the combination of the two increase the computing power by a factor of ten.

Ye Fei was puzzled.

But in scientific research, there are too many unknowns.

Scientific research is to find the truth in countless attempts.

A lot of experiments, you don't need to know why, and that's how it happens.

It's the same as why people drink water and why they are hungry.

Ye Fei called Dean Guan and said, "Dean, can you come over for a moment, I have made a major discovery here." ”

A moment later, the dean arrived and asked, "What major discovery?" ”

Ye Fei pointed to the computing power on the screen and said, "Dean, please take a look." ”

"Five billion billion hashrate?" The dean's eyes widened in surprise: "Wasn't it still 500 million computing power some time ago?" Why is it 5 billion computing power now? ”

Ye Fei shook his head and smiled bitterly: "You ask me, I can't explain it to you clearly, it's like this......"

Ye Fei told the dean about the matter.

"Are you saying that you prove a part of the problem of n and np, and then add it to the mathematical algorithm, and this is the result?"

"Hmm!" Ye Fei nodded.

"You don't know why?"

Ye Fei said helplessly: "I really don't know why this is happening, I can only say that it is too unscientific." ”

"Let's look into it."

In the next period of time, the two studied together the reasons why the 5 billion computing power was increased.

Half a month later, Ye Fei frowned and said, "You mean quantum computers?" ”

"Hmm!" The dean nodded and said excitedly: "I really didn't expect that your research would inadvertently enter the field of quantum computers. ”

"That would explain why the computing power has suddenly increased tenfold."

"Quantum computers are the development path of future computers, and they are also the mainstream research direction now."

"Five billion computing power is far from the computing power of a quantum computer, and the computing power of a quantum computer is at least 100 billion computing power."

"And the reason why we can only increase the computing power by 5 billion is because the hardware of supercomputing is not suitable for quantum computers."

"If there is the right hardware, the computing power should reach 100 billion."

"Hmm!" Ye Fei nodded, surprised at his luck, he actually touched the threshold of the quantum computer.

"The data is sealed, report it!" The dean said: "This matter can't be hidden, let the people above come down." ”
