Chapter 61

After the first round of screening, only nine of the twenty questions remained.

But what surprised Gu Luli was that the plane geometry problem, which was obviously one level of difficulty than IMO, was not eliminated in the first round of screening.

At that time, it was proposed to eliminate the fifth question of plane geometry, which is the highest difficulty geometry question, which was Park Changqu, who was sitting next to Gu Lu.

South Korea's ranking in the IMO arena has been making steady progress in recent years.

In Gu Lu's era, the ranking of the Korean team was still hovering around 10.

But a few years later, the South Korean team is no longer the same.

Especially last year, the South Korean team beat veteran powerhouses such as China and the United States to reach the top.

Park Changqu has only one goal this year, that is, to allow the South Korean team to successfully defend the IMO team championship.

The six Korean team members were all selected through numerous selections.

Among them are three players, and they are the IMO gold medal winners last year.

Such a lineup made Park Changqu feel confident that he was almost sure to win this team championship.

But now, an accident has happened.

A question that is obviously not an IMO level actually appeared in the alternative question bank.

Park Changqu tried to do that question when reviewing the question just now.

It's very difficult!

This is the evaluation given by Park Changqu, who graduated from the Department of Mathematics.

If the Korean players were asked to do this question, perhaps only Kim Antai would have the chance to get full marks, and the other five people would be very difficult to get half of the score.

This is a time bomb.

Once stepped on, not only the South Korean team, but also the other competitive powers will suffer.

So Park Changqu was the first to propose to eliminate this problem.

The team leader of the US team, Russia team leader and Yingguo team leader successively agreed.

But then, the Bulgarian team leader, intellectual team leader, Iceland team leader, and other team leaders of more than 20 small countries raised objections, believing that this question should be included in the alternative list of questions.

The purpose of these small countries is obvious.

Anyway, the players in their national team are very weak, and they are completely different from those of the competitive power players.

The middle and high-level questions can be solved by players from strong competition countries, while the players from weak countries rely entirely on luck.

It would be better to just break the jar and throw it away.

Choose a question that no one can do.

In this way, we can't get points, and you don't think about scoring.

The meeting was caught in a quarrel, and the two sides held their own opinions and did not give in to each other.

Unlike the panic of most competitive power leaders, Gu Lu leaned on the back of the chair and admired the good scene in front of him.

In the training of national team members in the past few days, in addition to the content of the examination syllabus, Gu Lu has also expanded some contents outside the scope of the syllabus.

Gu Lu focuses on geometry and number theory, so he expands particularly much on these two aspects.

Just in time, Gu Lu has popularized several members of the national team to solve the fifth problem of plane geometry in front of him, the Menelauss theorem and knowledge of affine transformation groups required.

Even in his heart, Gu Lu prefers this question and is selected into the final list of questions!

Seeing that the debate had no result, Chairman Andre could only use the simplest and most crude way - vote!

Voting results: 75:38.

Those small countries won by their advantage of being crowded with power.

…………

Next is nine to choose three.

Nine questions, two plane geometry questions, three algebra questions, two primary number theories, and two combined math questions.

According to convention, the three questions of IMO every day should belong to three different directions.

Therefore, the voting rule is that each person can only choose three questions in three different directions per vote.

Voting time is five minutes.

Park Changqu first whispered to the leaders of several national teams next to him, and then turned his head to Gu Lu's side.

"Team Leader Gu, I have already agreed with the team leaders of several other countries that we will continue to solve the fifth geometry problem!"

Park Changqu is really scared.

Once the fifth question of Geometry is chosen as the main topic, it will inevitably add many variables to the Korean team's championship.

"I think the fifth question of geometry is very good, why do you need to brush it down?" Gu Lu turned the pen in his hand and said with a smile, "The more difficult the question is, the more it can test the true level of a team, isn't it right?"

As he said that, Gu Lu called a check mark at the fifth question of geometry in the voting form.

Park Changqu: “…”

This Gu Lu...he is crazy!

Indeed, the harder the problem is, it is a good thing for a competitive power like them.

But this difficulty also has certain limitations!

If it is too difficult, it will have a counterproductive effect.

For example, let a high school student do a math problem after taking the postgraduate entrance examination.

Even if this high school student is such a genius, he will never get full marks.

Park Changqu has no idea about the purpose of Gu Lu's operation.

Is it self-confidence?

Or conceited?

Or they want to die together.

You should know that the Chinese team has performed poorly in the IMO field for several consecutive years.

The style of the former IMO overlord is no longer the same.

This time, Gu Lu did this, perhaps because he wanted to pull them and several of the competition powers to fall from the altar together.

…………

The voting form was collected and counted, and the results were soon released.

The three questions on the first day of IMO in the afternoon are the fourth question of elementary number theory, the first question of algebra, and the fifth question of plane geometry!

The scene that Park Changqu least wanted to see happened.

He turned his head to look at Gu Lu, and saw a calm expression.

Chairman Andrei sat in the main seat and looked at everyone, "The question has been selected, let's determine the answer and the scoring details below."

When countries submit questions, they all come with a standard answer.

Is there any omissions in this standard answer, or is there any other solution to the problem?

The standard answers to the three questions are submitted to the large screen in the conference room.

The most difficult plane geometry question is the best rated.

Because there are only two solutions, one is to use Menelauss' theorem and affine transformation group knowledge, and the other is to use complex derivation purely using high school knowledge.

Just looking at the dense formula symbols presented on the screen, many coaches felt their scalp numb.

The leaders of some major competition countries, including Park Changqu, frowns became increasingly tight.

After about ten minutes, everyone discussed the rating details.

Since I never thought that several people would come up with this question, the phenomenon of being petty and chewing on words that appeared in several sessions did not appear.

The elementary number thesis in question the first question is the easiest of the three questions.

For those team members from all over the country, it can be said that it is a complete free-to-point question.

In addition to the standard answers, everyone also discussed two other solutions. After determining the scoring details, the question was successfully passed.

In the end, only the second question remains.

An algebra problem that was enough to be regarded as the third question in the past.

But this year, because of the abnormal difficulty of geometry, I can only be ranked second.

…………

PS: In the new week, please vote for recommendations!!

The ranking has dropped to more than 400.
Chapter completed!
