Rule system

Mathematical Olympiad is a very formal test, and the invigilator cannot stand next to a student for a long time, otherwise there will be suspicion of cheating.

Wu Youqiang took a few glances and walked away.

After that, the number of times he'passed by' increased significantly, and he was sure that he had not made a mistake. Zhao Yi did indeed jump very seriously when doing the question.

If you can understand only by doing the questions, you can't understand at all.

The last big question is very difficult. Wu Youqiang knows that he can't do it in a short time after a few glances, but he still knows the general direction of thinking.

Divide the question into ten steps, and other people do the questions from the first step to the tenth step.

Zhao Yi is different.

He first wrote the fifth step, then became the seventh step, and then skipped to the second step?

Then, the fourth step.

The ninth step.

and many more.

When the previous conditions were not perfect, he directly wrote the last step.

There is not much on the paper, the steps are still messy, there is no logic at all, it seems to be deliberately disrupting the answer, but when copied on the test paper, the steps become very clear, and the calculation is clear step by step. Same as writing standard answers.

"This Zhao Yi is really amazing!"

"No wonder the Rubik's Cube calculator can be made, so many experts in the computer field feel incredible..."

"This is a genius!"

Wu Youqiang couldn't help sighing.

He can see other geniuses, but the genius in front of him is completely incomprehensible. He feels that he can't even keep up with his thinking.

They don't seem to be from the same world.

Zhao Yi didn't know that any invigilator was paying attention to himself. He used research coins and learning coins, causal thinking and focus mode, so that the body and mind were fully devoted to the test questions.

Unless there is a big movement, or I take the initiative to pay attention, I don't even know the teacher is passing by.

After copying the answer to the last question on the test paper, Zhao Yi reviewed the question again, using the "Law of Causality" to test the results one by one, and raised his head without any problems.

There are five minutes remaining in the exam.

The invigilator is already reminding, "Pay attention to the time, there are five minutes left!"

Zhao Yi checked the name and the candidate's serial number again, and there were no errors. After hesitating, he waited for a few minutes. The invigilator took the papers and walked out of the examination room.

He walked along the flow of people, waiting for Sun Liang at the door.

When he arrived at the door, there were two reporters standing next to him. He didn't care about it. It was normal for reporters to come to the Mathematical Olympiad. He didn't expect the reporter to wave at him. Another female reporter rushed over with the microphone for fear of him Just walk away immediately.

"Hello?" Zhao Yi was a little strange.

In fact, it is not surprising that a reporter interviewed him, but the popularity of the previous period has ended. You can still find his news on the Internet, but you rarely see reporters in your life.

He is not a star after all.

Whether it's a Rubik's Cube calculator or a third-order Rubik's Cube blindly twisting the record, the heat belongs to the matter, not his own, and the heat of the matter passes.

The female reporter did come to him, "You are Zhao Yi, the maker of Rubik's Cube, right?"

"Yes?"

Zhao Yi used an uncertain tone, and simply refused to admit it when he was in trouble.

"I heard that you are in this examination room, just waiting here." The female reporter's tone was very kind. When she was talking, the cameraman followed along, and the camera was directed at Zhao Yi, "I'm from Nanjiang TV Station. Journalist. At present, many people at home and abroad are concerned about the core algorithm of your Rubik's Cube. It is said that you want to publish related papers, right?"

Zhao Yi nodded.

"Then do you think about what periodical or magazine you want to publish in?" The female reporter pointed the microphone at Zhao Yi.

The interview place was at the entrance of the examination room, and the students who had just walked out also surrounded it, making the entrance seem a bit congested.

Zhao Yi glanced left and right, and simply stepped to the side of the road, "Here it!"

"it is good."

The cameraman helped keep the onlookers farther away.

The person next to him also twittered, "I know him, Zhao Yi, the creator of the imitating calculator."

"He is amazing and broke the Rubik's Cube world record. Now everyone calls him the'Cube Expert'."

"I didn't expect me to take the Olympiad with him."

"I'm together! I remembered that he was sitting next to me during the exam, and the invigilator paid special attention to him. He kept passing by. I was really depressed."

"..."

Zhao Yi looked at the person next to him a little helplessly. He didn't like being so eye-catching, so he simply said in short, "I have already submitted the paper, it is in "Journal-of-the-ACM", I hope it will pass."

"By the way, if the interview is really going to be broadcast, I would like to thank Professor Hemin Liu from the Academy of Sciences for giving a lot of guidance during the writing of the paper."

"That's it."

What Zhao Yi said was blunt enough, but he overestimated ordinary people's understanding of academia.

The female reporter asked in a daze, "Where did you say the publication was, can you say it again?"

"Journal-of-the-ACM? Journal, of, the, ACM, well, it's a journal sponsored by the International Computer Association."

This time I understand.

The female reporter obviously did not intend to let Zhao Yi off easily. She continued to ask, "You just said you want to thank Professor Liu Hemin, right? Can you introduce Professor Liu Hemin?"

Zhao Yi nodded and said, "Professor Liu Hemin's academy of sciences research in the field of artificial neural networks has reached the top level in the world."

He said simply, "If you want to know more, you can go online and search..."

The female reporter continued to ask, "Can you talk about the Olympiad? How was your exam this morning?"

"Okay."

Zhao Yi replied somewhat conservatively.

"Can you estimate a score? How much can you test?" the female reporter asked with interest.

Zhao Yi thought about it hesitantly, "If you judge by the result, it should be a full mark? I'm not sure if the process counts."

"Hula~~"

The students around could not help exclaiming.

Even if it's just an Olympiad, you dare to say that the result is right, and you may not find one in an examination room.

Zhao Yi answered a few more questions and found that Sun Liang, who had come from a distance, had quickly left on the grounds of something wrong. He didn't want to be watched by so many people.

In fact, the interviews conducted by female reporters are mainly for papers.

It is an exaggeration to say that "the whole world cares about Zhao Yi's paper", but many people who are engaged in computer field research are really concerned about the core algorithm of the Rubik's Cube.

Cracking the Rubik's Cube has always been a world problem.

This problem has plagued scientists for decades. They have been trying to simplify and simplify the algorithm, but because the number of calculations is too large, it is still far away to solve it.

The Rubik's Cube calculator proved to be correct, and the core algorithm involved must be very interesting.

Now someone has given Zhao Yi the title of'Future Turing Award Winner'. With the core algorithm of Rubik's Cube Calculator, he may be nominated as a Turing Award candidate.

Of course.

Before the paper was published and others did not see the core algorithm, everything was just speculation and prediction. They were still very concerned about Zhao Yi's paper.

Shirley Kamani is also one of the people who follow.

As a Ph.D. in computer, a PhD in biology, and a professor who mainly studies biology, Kamani is more concerned about the application of computers in biology, and the application of some computer algorithms to biology is really interesting.

Kamani is now the reviewer of Zhao Yi's paper.

Even without a special greeting from Professor Liu Hemin, Kamani would pay attention to Zhao Yi's paper.

"Journal-of-the-ACM" accepts a lot of submissions, but most of the submissions are "to be published", or simply "total impossible to publish" because the research content is meaningless or repetitive research , Or simply a piece of paper.

Zhao Yi is different.

The core algorithm of the Rubik's Cube calculator has been directly put into use and has been verified to be the correct algorithm.

This algorithm is highly valued by the computer community. Even the International Computer Association has many people who are paying attention to the upcoming papers. When they learned that Kamani was in charge of reviewing the manuscripts, many people even called to urge them. , "Quickly review the manuscript! It will be published in time for the next issue!"

Kamani felt the pressure.

During the review process, Kamani was attracted by the content.

Most simplification algorithms use mathematical'group theory', or other mathematical methods, to eliminate duplication and simplify data. There are also'carry-screening methods', but they involve'only imaginable calculation orders'. Simple screening becomes extremely difficult.

The'effective and irrelevant carry-screening method' gave Kamani a feeling of getting rid of the clouds, and the step of screening out'harmful' is obviously much easier than screening out'beneficial'.

Some of the algorithms and conclusions in the'screening method', the formulas and theorems used in the proof process are not sophisticated, and most of them are very simple and definite formulas, which makes the conclusions more certain.

Kamani was fascinated by it.

The'effective and irrelevant carry-screening method' always means a shortcut. It is not easy to understand the proof process, and it is even more difficult to understand it completely.

Professor Liu had been discussing algorithms with Zhao Yi, and decided to come to Zheng Yang and Zhao Yi to talk in person.

Others just read the paper and think about their feelings.

Kamani watched carefully all morning, and he didn't go to review the manuscript at all, and directly gave the "review passed".

Review the manuscript without fully understanding it.

Most academic paper reviewers do not need to understand the content at all, because cutting-edge research in the world is difficult to understand. The most important thing for reviewers is to make sure that the manuscript meets the standards and is eligible for publication in a magazine.

After giving the "review passed", Kamani remembered his work.

She is a professor at Oxford University!

She immediately called the admissions department of Oxford University, "Do you know the maker of Rubik's Cube? That Chinese high school student, Zhao Yi, I got his paper."

"If you want to miss a future Turing Award winner, just continue to stay in the office for tea!"
