When Wang Hao returned to the office in the complex building, he felt that the atmosphere was a little strange.
Others were a little better. They just glanced this way and said hello normally, but their eyes looked a little strange.
Zhu Ping, on the other hand, can't hold back her words. When she is holding something back, it can be clearly seen. For example, she took the initiative to make coffee for Wang Hao and acted like a friendly and good colleague.
Wang Hao was busy saying "thank you" several times.
Then Zhu Ping moved a stool and sat down next to her. She said she had some research questions. Seeing people coming and going at the door, she just sat there, hesitating and not speaking.
When Wang Hao asked about it, he was obviously talking about him.
If Wang Hao didn't have some understanding of Zhu Ping's character, he would have thought that this eldest sister was planning to do something evil to him.
Fortunately, not long after, the department chair called Zhu Ping away because of something.
Wang Hao breathed a sigh of relief.
After Zhu Ping left, the office became lively. A female teacher named Deng from the adjacent office came over to 'drop in' and talked about the student exams, complaining that there were several students in the class who had scores over 50.
"What should I do? If I get 58 or 59, I can go up by two points. If I get 60, I will pass."
"As a result, several students scored 53.4 points."
When this topic was mentioned, it immediately caused a lot of complaints.
Yan Jing also followed up and said, "It's the same in my class. Many students don't study at all. I have already highlighted the key points and will test the questions in the exam. As a result, many students still made mistakes. There was even a student who looked at it during the exam.
Cheat sheet, got caught and got zero points."
Teacher Deng immediately said, "The one who got zero marks for reading the cheat sheet, I know, is Meng Lili from the laboratory building who proctored the exam. Meng Lili is very young, less than thirty, she is really pissed off."
"Let's just read the cheat sheet, or at least read it secretly? That student put it on the table to read it. Teacher Meng passed by, but he didn't pay attention at all and continued to read."
"This is the first time I've seen such an arrogant student in several years. I guess it's just because Teacher Meng is young."
"Bala bala~~~"
Teacher Deng is obviously a very gossipy person, no worse than Zhu Ping. In the process of complaining, he clearly explained the whole story.
Seeing others discussing the matter together, she stopped talking with satisfaction, turned to look at Wang Hao, and asked casually, "Teacher Wang Hao, how is your class? You have just been teaching for three months, right?"
Are you judging the case?"
Wang Hao pointed to the test paper on the table and said with a headache, "There's still half of it."
Teacher Deng walked over and flipped through it, and immediately said in surprise, "The classes you teach are good, and all the big questions have been answered."
Wang Hao explained, "I told them that the big questions are the usual homework questions. The question types are the same, just change the numbers. As long as you review them, you should be able to do it."
"That's not true!"
Luo Dayong immediately denied it, "My "Probability Theory" gave them a total of ten questions before the exam. It was clearly stated that the three big questions in the test paper were in it, and the three big questions accounted for sixty points. The result...
"
He shook his head as he said, "Only half of them passed the examination paper." After that, he added, "It probably has something to do with the strict invigilation of the exam."
Wang Hao listened to Luo Dayong's statement and looked through the dozens of test papers he had just judged. He basically answered all the big questions correctly. He nodded happily, "Maybe it's because the students in the classes I teach love to study more."
.”
This sentence triggered 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. You should be strict now. Students, they don't study. They don't study before many exams. They all rely on cheat sheets. How can they do it?"
?"
"Bala bala~~~"
There was a teacher who kept talking next to him, which made Wang Hao feel quite good. He was judging the papers for the students while listening to the storytelling...
Good!
More than 300 test papers were judged one after another. Recording students' scores and entering them into the computer was not an easy task.
Wang Hao was busy for more than two hours.
Teacher Deng had already left. The others had finished their work and looked at the time to prepare to leave.
Zhang Zhiqiang stood up first, walked outside to the door, patted Wang Hao on the shoulder, and whispered, "Congratulations, I heard about that. Don't worry, no one else knows."
Luo Dayong followed behind and gave Wang Hao a thumbs up, "Journal of Mathematics, it really worked this time!"
Yan Jing was the last to stand up. She moved to Wang Hao's side and asked, "Are you done?"
"Not even close."
"Well... that's it..." She hesitated for a moment, but finally said it, "When your paper is published, let's celebrate it together."
"...Um, okay."
Wang Hao didn't know what to say. He finally knew why everyone else had strange expressions when he entered the office.
At this time, Zhu Ping came back from outside, looked at Wang Hao, then at Yan Jing, stood at the door for a long time, and finally said, "Wang Hao, your paper... Yan Jing is not someone else anyway, so I
…”
Wang Hao rolled his eyes hard and said with a mixture of laughter and tears, "Sister Zhu, please stop holding it in, it doesn't matter who you are. Everyone in our office knows about this except you.
Already."
"——?"
Zhu Ping almost had the word "confused" written on her face. She thought about it for a long time, but still didn't understand the logic.
Yan Jing couldn't help but laugh.
…
The fact that the "Journal of Mathematics" published the paper was only circulated among the school faculty and staff. Since it was not actually published, other people only knew the news and it would not have any impact.
The end-of-semester paper judging work is over and time has entered the holiday season.
University teachers also take summer vacations with their students.
Some young faculty members who are under great pressure from scientific research will still come to school and laboratories frequently, but since they do not need to perform teaching work, it naturally becomes much easier.
Wang Hao, on the other hand, couldn't relax. He was about to take part in STACS. After submitting the visa application, he still had to prepare various materials, find the school to issue reports, etc.
Don’t worry about air tickets and hotels.
Dean Chen Qinghua from the School of Computer Science came over and talked about attending the STACS conference. He introduced him to a scholar who was attending the conference together. After contacting him, they agreed to set off from the capital together, and the other party directly booked air tickets and hotels.
Two days before the meeting, Wang Hao took a plane to the capital and met the people who were going with him in the airport hall.
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 slightly curly hair looks a bit messy.
Wang Hao had seen Ruan Hailong's photo and recognized it at a glance. He waved and shouted, "Professor Ruan, here!"
Ruan Hailong dragged his suitcase and 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. I didn't expect you to be so young!"
Wang Hao smiled and said, "You are also very young."
"No comparison!" Ruan Hailong shook his head with a wry smile. At the age of thirty-six, he could be called a 'young scholar' wherever he went, but when he walked with Wang Hao, he could only be called 'old'
Already.
The two of them went to pick up their tickets together, checked in their luggage, and then busily entered the international flight aisle.
After we found a small restaurant and sat down inside, we had time to chat quietly for a few words. Ruan Hailong talked about the news from a while ago and talked about Wang Hao's ten papers.
Then the topic turned to new content, "I heard Professor Chen say that you are going to give a report, right? What is the content?"
Wang Hao nodded and said, "Large number multiplication algorithm."
Ruan Hailong was surprised and immediately reacted, "Should we make improvements or use a new calculation method?"
The former is a small increase in calculation speed, while the latter may make the algorithm usher in a qualitative leap.
The results of the two are not of 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 the calculation, but there are some innovative calculation methods in the algorithm."
Ruan Hailong nodded after listening, and the two of them had a meal based on the topic, and then went to the departure hall at about the same time.
Check in and board the plane.
When he sat on the plane's seat, Wang Hao breathed a sigh of relief, but the long journey had 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 Acta Mathematica and has been confirmed to be published?"
"..."
Wang Hao's expression suddenly froze, and he couldn't help but think of two people, one named Li Ming and the other named Zhu Jianrong.
They said, ‘It will never be spread out’.
As a result, not only the faculty and staff of our school, but also the professors at Xijing Jiaotong University thousands of miles away knew about it?
…
During a long flight, I just hope to sleep and rest, but it is impossible to sleep forever. Fortunately, I have Professor Ruan with me, who can not only look after each other, but also find topics to chat with.
Ruan Hailong is a very good doctor of information science and has participated in several large projects.
He talked about one of his experiences, "I went to the supercomputing center. The computers in the supercomputing center are very powerful. My colleagues and I compiled a code to crack the Rubik's Cube. As long as we input the status of the Rubik's Cube, we can know it in the blink of an eye.
How can I restore it to its original state?”
"The fastest way?"
"Usually not."
Ruan Hailong explained, "The code we designed is very simple and will be calculated using the exhaustive method. As long as a path is created, the program will stop. I tried it with an ordinary computer. Sometimes, it can be cracked in a few seconds.
Sometimes, it takes a little longer.”
Wang Hao thought about it and said, "Can't we find the best path? I remember that there seemed to be an American team that studied it, and the number of God is twenty."
Ruan Hailong said nonchalantly, "They also used the exhaustive method to find the minimum steps, but they just used a better supercomputing server. After all, the amount of calculation is too much."
"Is there a way to reduce the amount of calculations?"
"It's difficult, almost impossible."
Ruan Hailong said with certainty, "This, I feel, 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 have also thought about it carefully..." He said and shook his head.
The two of them just talked about the problem, just like gossiping, just like normal things.
Wang Hao thought more. It would be a good opportunity to attend a meeting to give a report. He must set up a task to gain inspiration points.
He has never thought about setting up any mission.
If it is mathematics, it will be very easy. In the computer field, a lot of research needs to be done by a team, not by individuals.
What Ruan Hailong said inspired him.
yes!
"If we find a way to calculate the minimum steps to restore the Rubik's Cube, or in other words, prove the number of God, it will definitely be a breakthrough achievement."
"That's not just a Rubik's Cube problem. There are many similar problems involving exhaustive calculations in scientific research and application fields..."
He thought about setting up a task immediately.
【Task 2】
[R&D project name: The number of God to crack the third-order Rubik's cube (difficulty: A).]
[Inspiration value: 0.]
[Complete A-level difficulty research and obtain additional teaching coins: 1000.]
[After completing the task, you will receive a teaching coin reward.]
