There was nothing much to say about the opening ceremony the next afternoon.

The leader’s speech plus the team leader’s representative’s speech.

Anyway, he is not Chinese, so he speaks English.

There were simultaneous interpretation headphones on site, but not many people wore them.

At this point, the Chinese team and the American team would compete with each other from time to time.

It's probably a competition among several children to see who can show the slightest bit of contempt with their eyes.

From this point we can see that competition in different civilizational contexts is all-round.

Even if you are better at using your eyes to express yourself, it is something to be proud of.

It's just that the result of this competition is probably that both sides feel that they have won.

It achieves the purpose of making the other party feel guilty just by looking at it.

Of course, the results will have to wait until the next day to be tested in the examination room.

…

The competition started on time at 8:30 a.m. the next day.

Because the questions provided by the organizer are all in English, we will work with the team's translators in advance to translate the questions into the native languages ​​of other countries.

Of course, if the candidate's English level is high enough, they can also write their own original questions.

The team leaders from these countries have already explained this to the candidates.

I'm afraid the only thing the team leader didn't explain is that before entering the examination room, all the candidates saw fifteen curtains with white paper posted neatly at the entrance of the examination room.

"What is this for?"

Not to mention the candidates who had questions, even the team leaders from various countries found it baffling.

This is not the first time for most of the team leaders to lead a team to participate in the International Mathematical Olympiad.

This is the first time I have seen so many screens placed in front of the prepared examination room.

Are there any new tricks to be played in this year’s Mathematical Olympiad?

I paused for a long time, but not a single word was written on the white paper, which made me feel melancholy.

However, some people only felt excited when they saw this scene.

Yes, of course they are Chinese children.

Wang Yufei's plan was not hidden from them. Even though they were beaten to death, they didn't expect that these things were actually prepared.

So next, Wang Yufei is really going to solve a mathematical problem that is plaguing the world while taking the Mathematical Olympiad exam?

Well, Wang Yufei has done everything he can, and what they have to do now is probably not to hold their own people back.

Although they are all arrogant children, sometimes some people are dissatisfied.

…

The examination room was an empty auditorium renovated.

Therefore, the curtain board is actually placed behind all the candidates, that is, separated by barriers. You can see it when you turn around.

But the candidates are professionals after all.

It's just a dozen blank baffles, so naturally no one will pay too much attention to it.

Everyone is here to compete for ranking.

The time for the International Olympiad is even tighter. It takes 4 and a half hours to solve three problems, leaving them only one and a half hours to think and solve each problem.

It sounds like a lot, but think about it. Every Olympiad question is researched by a bunch of mathematicians who racked their brains.

The purpose is to comprehensively assess the abilities of mathematical geniuses from various countries. The six questions cover all aspects of algebra, geometry, combination, and number theory.

Each question is worth seven points, and the total is only forty-two points.

There are few points, so you must solve the problem thoroughly in order to score. If you accidentally miss a step in the problem, you may be deducted. Of course, you must take it seriously.

Especially the difficulty of each question is different.

Generally speaking, the last question is the most difficult, and an hour and a half may not be enough.

At this stage of the International Mathematical Olympiad, the test is no longer just about calculation, but more about mathematical imagination.

Then, shortly after most of the contestants had just finished solving the first question, someone stood up and submitted their answer sheet.

That's right, you didn't go to the toilet, you submitted your answer sheet?

"?"

Many people recognized this figure.

Isn't this just a member of the Chinese team who wants to compete with the American team?

So is this guy serious?

He is actually serious?

Come to the International Olympiad to compete in speed?

Many people subconsciously looked at the watch hanging on the big screen in front.

Very awesome!

Just one hour and twenty-five minutes passed.

In other words, each of the three questions takes less than half an hour to solve.

The legendary quick shooter?

The kids on Team USA were collectively stunned.

Is it really possible to play like this?

Is this giving up one person's results and hoping to beat them in total points?

Originally, everyone agreed to try to finish it ten minutes in advance. Six people can finish it one hour in advance.

But the other party was more than three hours ahead of schedule!

Chinese people are crazy!

This is the thought that comes to everyone's mind at this time.

However, this figure just walked out of the examination room silently, then stopped in front of the neatly arranged curtain, then took out the pen in his hand and started writing on the cardboard.

The strange scene attracted the attention of many candidates, but at most they only looked back once or twice before forcing their attention to the test questions in front of them.

Damn it!

When others go crazy, they can't follow them!

I have just finished solving this problem.

…

Of course, candidates should not be distracted, but after all, someone knows what Wang Yufei is doing.

Soon several mathematicians from various countries gathered around.

Most of them are experts in mathematics invited by the organizing committee of this International Mathematical Olympiad.

Even Phillips himself.

After all, agreeing to this incredible proposal was based on curiosity.

He really wanted to see if any member of the Chinese team could accomplish such an incredible thing.

The test paper submitted by Wang Yufei was immediately taken to the expert team members for correction at his request.

Now he and other mathematicians have to see what problem this Chinese student wants to solve.

…

Wang Yufei never cared about the presence of onlookers.

He is fighting a respectable opponent, and will naturally attract some attention in the process.

Wang Yufei still understands that there are gains and losses.

And when you are really immersed in the idea of ​​​​solving a problem, your brain can automatically block everything outside temporarily, unless someone talks to you specifically, or there is danger.

But obviously no one will disturb him at this time.

…

The twin prime conjecture is whether there are infinitely many prime numbers that differ by 2.

I am interested in this question because studying prime numbers can be used in data structures and algorithms.

In addition, there are Mersenne primes and Goldbach's conjecture.

But Wang Yufei has not yet fully thought through these two issues.

He just felt that he could vaguely find the 51st Mersenne prime number.

But he didn't want to announce it on this occasion, so he had no choice but to use twin prime numbers for surgery.

And number theory has always been the most challenging area of ​​mathematics.

Soon, Wang Yufei wrote the first row of calculations on the whiteboard.

s(a)=Σane(na); m,n∈ζ……

Then write faster and faster.

…

"The answer is revealed. He wants to prove the twin prime conjecture."

After Wang Yufei completed a cardboard, a mathematician said.

"This child..."

"Chairman, the child's results are out..."
Chapter completed!
