From university lecturer to chief academician.

Chapter 49 A Level Difficulty Task

When Wang Hao returned to the office of the complex building, he felt that the atmosphere was a little weird.

The others were a little bit better, they just glanced this way and said hello normally, but their eyes looked a little strange.

Zhu Ping was 'unable to hold back' her words, and when she was holding back something, it was obvious. For example, she took the initiative to make coffee for Wang Hao, showing the appearance of a friendly and good colleague.

Wang Hao said 'thank you' several times in a hurry.

Then Zhu Ping moved a stool and sat next to her, saying that she had some research issues, and seeing people coming and going at the door, she just sat there, hesitating and not speaking.

When Wang Hao asked about it, he obviously talked about him from left to right.

If he didn't have some understanding of Zhu Ping's character, Wang Hao would have thought that this eldest sister was planning to plot evil against him.

Fortunately, not long after, the head of the department called Zhu Ping away because of something.

Wang Hao let out a sigh of relief.

After Zhu Ping left, the office became lively instead. In the next office, a female teacher surnamed Deng came to 'stop in' and talked about the student exams.

"What should I do? If you get 58 or 59 in the test, you can get two points, and if you get 60, you will pass."

"As a result, several students scored 53 or 4."

When this topic was mentioned, it immediately caused a lot of complaints.

Yan Jing also said, "It's the same in my class. Many students don't study at all. I have already drawn the key points. I will test the questions in the exam. In the end, many students still make mistakes, and there is even a student who looks at it during the exam. Cheat sheet, was caught and scored zero points."

Teacher Deng immediately said, "The one who got zero points for reading the cheat sheet, I know, is the invigilator Meng Lili from the laboratory building. Meng Lili is very young, less than thirty, she was really pissed off."

"If you want to read the cheat sheet, just read the cheat sheet, or at least secretly read it? The student just put it on the table to read it. Teacher Meng passed by, but he ignored it and continued to read it."

"It's been several years, and this is the first time I've seen such an arrogant student. I guess it's because Mr. Meng is young."

"Balabala~~~"

Teacher Deng is obviously very gossip, not worse than Zhu Ping at all, explaining the whole story clearly in the process of complaining.

Seeing other people discussing the matter together, she stopped talking in satisfaction, turned her head to look at Wang Hao, and asked casually, "Mr. Wang Hao, how is your class? You have only been teaching for three months, right? Are you judging the papers?"

Wang Hao pointed to the test paper on the table and said with some headache, "There is still half of it."

Teacher Deng walked over and looked through it, and immediately said in surprise, "The classes you teach are all right, and all the big questions have been solved."

Wang Hao explained, "I told them that the big questions are the usual homework questions. The question types are the same, so just change the numbers. As long as you review, you should be able to do it."

"That's not it!"

Luo Dayong immediately denied it, "My "Probability Theory", I gave them a total of ten questions before the exam. It was clearly stated that there were three major questions in the test paper, and the three major questions accounted for sixty points. The result... "

He shook his head as he said, "Those who pass the paper, half of them." After finishing speaking, he added, "It probably has something to do with the strict invigilation."

Hearing what Luo Dayong said, Wang Hao flipped through dozens of test papers that had just been judged, and found that all the major questions were basically correct, so he nodded in relief, "Maybe, the students in the classes I teach are more fond of studying. .”

This sentence has caused a new round of topics.

Teacher Deng immediately pointed out, "Teacher Wang Hao is very strict. I heard that those students are afraid of you. They should be strict now. Students, if you don't study, you don't study before many exams. You can do it all by cheating." ?"

"Balabala~~~"

There was a teacher beside him who kept saying that it made Wang Hao feel pretty good. He was grading students and listening to storytelling...

Good!

More than [-] test papers were judged one by one, and it was not an easy task to record the students' scores and enter them into the computer.

Wang Hao was busy for more than two hours.

Teacher Deng has already left, and the others are ready to leave after finishing their work and checking the time.

Zhang Zhiqiang stood up first, walked outside to the door, patted Wang Hao on the shoulder, and said in a low voice, "Congratulations, I heard about that. Don't worry, no one else knows."

Luo Dayong followed behind and gave Wang Hao a thumbs up, "Acta Mathematics, this time it really works!"

Yan Jing was the last to stand up. She moved to Wang Hao's side and asked, "Are you done?"

"A little bit."

"Well...that's..." She hesitated for a moment, but said it anyway, "When your paper and that matter are published, let's celebrate together for you."

"...Uh, okay."

Wang Hao didn't know what to say. He finally understood why the other people had strange expressions when he entered the office.

At this time, Zhu Ping came back from the outside, looked at Wang Hao, then at Yan Jing, stood at the door for a long time, and then said, "Wang Hao, your thesis... Anyway, Yan Jing is not someone else, so I ..."

Wang Hao rolled his eyes hard, and said dumbfoundedly, "Sister Zhu, don't hold back, it doesn't matter who you are. Everyone in our office knows about this matter except you, everyone knows gone."

"—?"

Zhu Ping almost had the word "嗯" written on her face. She pondered over it for a long time, but still didn't understand the logic.

Yan Jing couldn't help but laugh out loud.

……

The publication of the paper by the "Acta Mathematica Sinica" was only circulated among the faculty and staff of the school. Because it was not actually published, other people just knew the news and it would not have any influence.

The end-of-term judging work is over, and the time has entered the holiday.

University teachers also take summer break with students.

Some young faculty and staff who are under great scientific research pressure still come to the school and go to the laboratory frequently, but because there is no need for teaching work, it naturally becomes much easier.

Wang Hao couldn't relax. He was going to participate in STACS soon. After submitting the visa application, he still had to prepare various materials, ask the school to issue a report, and so on.

Don't worry about air tickets and hotels.

Dean Chen Qinghua from the School of Computer Science approached him, talked about attending the STACS meeting, and introduced him to a scholar who attended the meeting together. After contacting him, they agreed to leave from the capital together, and the other party directly booked the air ticket and hotel.

Two days before the meeting, Wang Hao went to the capital by plane, and met the people who went with him in the airport lobby.

Ruan Hailong, 36 years old, is a professor at the School of Information Engineering of Xijing Jiaotong University. He is thin, wearing jeans and a gray shirt, and his curly hair looks a little messy.

Wang Hao saw Ruan Hailong's photo and recognized it at a glance. He waved his hand and shouted loudly, "Professor Ruan, here!"

Ruan Hailong dragged the suitcase, walked over and looked Wang Hao up and down, with a surprised expression, "I saw your photo and thought it was taken a few years ago, but I didn't expect it to be so young!"

Wang Hao smiled, "You are also very young."

"It's incomparable!" Ruan Hailong shook his head with a wry smile. At the age of 36, he can be called a "young scholar" wherever he goes, but when he walks with Wang Hao, he can only be called "older".

The two went together to pick up the air tickets, check in the luggage, and then hurriedly entered the international flight channel.

After we found a small restaurant to sit down inside, we had time to have a quiet chat. Ruan Hailong talked about the news some time ago, and talked about Wang Hao's ten papers.

Then the topic changed to new content, "I heard from Professor Chen that you are going to give a report, right? What content?"

Wang Hao nodded and said, "Large number multiplication algorithm."

Ruan Hailong was surprised, and immediately realized, "Should we improve it, or use a new calculation method?"

The former is to increase the calculation speed by a small amount, while the latter may make the algorithm usher in a qualitative leap.

The results of the two are not at the same level.

Wang Hao thought for a while and explained, "It should be improvement and innovation. I still use the Fourier transform to assist calculations, but there are some innovative calculation methods in the algorithm."

Ruan Hailong listened and nodded, the two had a meal on the topic, and then went to the waiting hall at about the same time.

Check in and get on the plane.

When sitting on the seat of the plane, Wang Hao breathed a sigh of relief, but the long-distance journey has only just begun.

Ruan Hailong was sitting next to him, and suddenly started a new topic and asked, "I heard from Professor Chen that your paper on the Monge-Ampere equation has passed the review of the "Acta Mathematics", and is it confirmed to be published?"

"..."

Wang Hao's expression froze immediately, and he couldn't help but think of two people, one named Li Ming and the other named Zhu Jianrong.

But they said 'absolutely do not spread out'.

As a result, not only the faculty and staff of the school, but even the professors of Xijing Jiaotong University thousands of miles away knew about it?
……

The long-distance flight is hoping to sleep and rest, but it is impossible to sleep all the time. Fortunately, there is Professor Ruan traveling with us. Not only can we take care of each other, but we can also find topics to chat with.

Ruan Hailong is a very good Ph.D. in informatics and has participated in several large projects.

He talked about one of his experiences, "I went to the supercomputing center. The computer in the supercomputing center is very powerful. My colleagues and I compiled a code to solve the Rubik's Cube. Just enter the status of the Rubik's Cube. In the blink of an eye, you can know How can it be restored to its original state."

"The fastest way?"

"Generally not."

Ruan Hailong explained, "The code we designed is very simple, and we will use the exhaustive method to calculate. As long as a path is opened, the program will stop. I tried it with an ordinary computer, and sometimes it can be cracked in a few seconds. Sometimes, it takes longer."

Wang Hao thought about it and said, "Can't you find the best path? I remember that there seems to be a team from American who researched it. The number of God is twenty."

Ruan Hailong said indifferently, "They also used the exhaustive method to find the minimum steps, but the supercomputing server used is better, after all, the amount of calculation is too large."

"Is there a way to reduce the amount of computation?"

"It's hard, almost impossible."

Ruan Hailong said affirmatively, "This, I think, should be a mathematical problem. Many people have studied it, and there are many calculation methods, but if you want to find the minimum steps to restore the Rubik's Cube, you can almost only use the exhaustive method."

"I've thought about it too..." He said shaking his head.

The two just talked about the problem for a while, as if they were chatting about gossip and family affairs.

But Wang Hao thought of more. It is a good opportunity to participate in the meeting to give a report, and he must create a task to get inspiration points.

He hadn't thought about setting up any missions.

If it is mathematics, it will be very easy. In the computer field, a lot of research needs to be done by teams, not by individuals.

What Ruan Hailong said inspired him.

Yup!

"If you find a way to calculate the smallest steps to restore the Rubik's Cube, or to prove the number of God, it will definitely be a breakthrough achievement."

"That's not just a Rubik's Cube problem. In the field of scientific research and application, there are many problems that involve exhaustive calculations..."

He thought about setting up a mission right away.
