Chapter 60

This incident is remembered by Park Changqu until now.

In the two years since that competition, he has been following Gu Lu.

Naturally, he also knew the fact that Gu Lu had won a perfect IMO score for three consecutive years.

It wasn't until Gu Lu entered the university that Park Changqu had no channel to learn about Gu Lu's dynamics, so he buried this emotion for Gu Lu in his heart.

However, in the room of Pu Changqu's bedroom, a photo of Gu Lu has been pasted.

It was Gu Lu's first time participating in the IMO, holding the trophy and standing on the podium with his teammates smiling.

At the time, the photo appeared in the newspapers.

Park Changqu specially cut out Gu Lu's image and pasted it in the most conspicuous place in the bedroom, always alerting himself.

This incident also made Park Changqu's parents worry about whether their son had awakened some strange attributes.

Gu Lu's appearance was already deeply in Pu Changqu's mind.

thought that in this life, he would never have any intersection with Gu Lu again.

But when Gu Lu pushed the door and walked into the conference room, at first glance, Park Changqu recognized that it was Gu Lu who he had been thinking about for six years.

And, like himself, he is also the leader of the national team.

Park Changqu realized that the opportunity he had been waiting for for a long time to defeat Gu Lu had finally arrived.

This time, he must have made Gu Lu feel his despair and unwillingness back then!

............

"Unexpectedly, Gu Lu, you are now the leader of the Huaguo team. Park Changqu smiled, "And I happen to be the leader of the Korean team." ”

Gu Lu glanced at Pu Changqu lightly, "So, what do you want to express?"

"Nothing. Park Changqu leaned back in his chair, "It's just a little emotional." Time has changed, and six years have passed, and both of us have changed from former national team players to national team leaders. But what hasn't changed is that we're still competitors. ”

"Team Leader Gu, are you interested, bet with me? Just bet on the ranking of our two countries' team competition this time. Park Changqu pretended to speak casually.

But his eyes were full of anticipation and nervousness, and he couldn't hide his thoughts.

In his heart, Park Changqu was extremely looking forward to Gu Lu agreeing to this bet.

However, Gu Lu just shook his head with a smile and replied simply and simply, "I'm not interested." ”

Park Changqu: "......"

"Idle is idle. Leader Gu is here to have fun, if you really don't have any money, I'll do it for you!"

Pu Changqu is very much like those old bustards in the ancient Qinglou at this moment.

While saying to Gu Lu, "Uncle is coming to play", he also helped Gu Lu to prostitute money.

Park Changqu is indeed in a hurry.

If Gu Lu didn't bet with him, even if he won in the end, the sense of accomplishment would definitely not be so high.

Park Changqu was about to reason with Gu Luxiao and move him with affection, but at this moment, the door of the conference room was pushed open.

A bearded, suit-wearing, man in his mid-fifties walked in and sat down at the head of the conference table.

Andrea Pisco, from the International Mathematical Union.

He is the chairman of the IMO topic selection committee, and in addition, he also serves as the general coordinator of IMO scores, which is similar to the position of the leader of the Huaguo marking team.

It can be said that he is the biggest boss in the current IMO.

As soon as Andre entered, the entire noisy conference room instantly fell silent.

Andre looked around the conference room and coughed lightly, "Now that we've got all the people here, let's start right away." ”

The schedule is tight.

The exam is scheduled at one o'clock in the afternoon.

After the topic selection committee has decided on the topic, it should also seize the time to determine all the methods of solving the questions and the scoring criteria, and then translate the questions into English, German, Japanese, Chinese, Russian, French and other languages.

Chairman Andrei waved to the assistant behind him.

The assistant opened the briefcase and took out a stack of A4 papers, which were printed with questions one after another.

Since there is still one day of exams tomorrow, only half of the total question bank was taken out for today's topic selection meeting.

That is, there are 5 questions each in plane geometry, algebra, elementary number theory, and combinatorics, with a total of 20 questions.

The assistant handed out a stack of A4 sheets of paper with 20 questions printed on each person.

In order to keep the questions confidential and avoid leaking, these topics have never been touched by coaches from various countries before.

Chairman Andre raised his wrist and looked at the time, "It's 8:41, and you have thirty minutes to review the topic. ”

Thirty minutes is for the team leaders from all over the world to have a preliminary understanding of these 20 sets of test questions.

Be clear about the difficulty factor of each question, as well as the direction and focus of the question.

Gu Lu spent about ten minutes reading the twenty questions and calculating them in his mind, and had a simple idea of the IMO test questions this time.

Most of the 20 questions belong to the ordinary IMO level, which is no different from previous years.

There are two exceptions.

A geometry problem, a number problem.

I don't know which country submitted the geometry problem, and it didn't look like people were going to score points.

If you don't know the concepts of Menelauss's theorem and affine transform groups, you must be completely confused when you see this problem.

And if you use high school knowledge to answer, Gu Lu estimates that you can't solve this question without more than 100 formulas.

As for the number question, it is a proof question.

It's just that this number thesis does not prove a certain theorem or a variant of a certain theorem, but a conjecture that has not yet been proven.

Although it is just a small conjecture without a name, and it does not require much advanced and complex college knowledge to solve it, it is still too impractical for a group of high school students to let them do it.

Half an hour later, Chairman Andre knocked on the table, "Everyone, stop. ”

He looked at the crowd, "Let's do the first round of screening first. ”

The purpose of the first round of screening is to eliminate a batch of questions that are obviously unrealistic.

Then the second round of screening is to determine the final test questions through voting.

Chairman Andre cupped his eyes and swept his gaze over everyone, "Let's talk about the five questions of algebra first, and express your own opinions." ”

The leader of the rice country is a tall white man, and he was the first to speak, "The first problem of algebra is actually a generalized variant of the Maher problem, and it is recommended to eliminate it!"

Greek Team Leader: "Seconded." ”

Danish team leader: "Seconded." ”

More than half of them seconded the proposal, and Andre directly decided to remove the first question of algebra from the list of pre-selected test questions.

Next, another Australian team leader said that the ternary inequality problem of the third algebra problem is very similar to the competition problem that the United States has just used to screen the national team, and it is recommended to eliminate it.

The team leader of the United States was also quick to admit this, so this question was also directly put forward to the shortlist.

After that, there was a long confrontation.

Before coming here, each coach had known in advance about the competition topics for selecting national teams in various countries, so once there were questions similar to those done by a certain country, they were directly eliminated.

There are also those test questions that can be similar on the Internet, which have also been put forward by team leaders from various countries and have been eliminated one after another.

In the end, there are twenty questions, and only the last nine are screened.

PS: The early bird has something to eat.

Today's first shift, there are two more in the back!
