Chapter 59

March 5th, the day before the IMO race.

In the hotel room, Gu Luzheng was racing against time with seven members of the national team, including Bi Qi, to provide final coaching for the competition.

"...Finally, let me tell you about De Moivre's theorem. Although the probability of passing the test is low, once you pass it, the difficulty level of the test questions will definitely not be small. If it is not placed on the third question, it will be placed on the sixth question."

"The specific content of De Mevere's theorem is composed of two complex numbers, which can be expressed in trigonometric form as Z1=r1(cosθ1isinθ1), Z2=r2(cosθ2isinθ2), then: Z1Z2=r1r2[cos(θ1θ2)isin(θ1θ2)

]. Moreover, De Mevere's theorem and Euler's formula are also closely related. If..."

Seven students from the national team listened carefully while recording meticulously in their notebooks.

Gu Lu's mathematical proficiency was witnessed by several people during the winter camp.

It can be said that we are not in the same dimensional concept as them at all.

Even their provincial team coach could only be pushed to the ground and rubbed against Gu Lu.

Therefore, several people were completely convinced by Gu Lu.

In the past few days, they did whatever Gu Lu said. When Gu Lu asked them to make up for their weaknesses, they tried their best to practice on the questions.

The time is until ten o'clock in the evening.

Gu Lu stopped teaching and glanced at the seven people in front of him, "Tomorrow is the IMO race. You just need to compete seriously. You don't need to worry about the rest."

"This time, we are here to win the team competition, so we need you to take every question seriously. Don't panic, let alone waste. Now you represent not only yourself, but also the country behind you!"

…………

The next day, the IMO main race started in the afternoon.

Just like CMO, there are two days, three questions every day, and the exam time is from 1 pm to 5:30 pm.

But in the morning, Gu Lu came to an office building within Imperial College alone.

In a large conference room, more than 70 team leaders from more than 50 participating countries have gathered.

The purpose of the leaders from various countries gathering here this morning is not to chat and exchange feelings, but to determine the three test questions for the first day of IMO in the afternoon.

There is a strict selection process for each IMO's six-question examination.

First, each participating country submits 20 to 30 questions to the organizing committee.

This work was completed in December last year.

Then in January this year, these more than 200 questions will be screened and only 40 questions will be retained.

Among them, there are 10 questions each in plane geometry, elementary number theory, algebra, and combinatorics.

Finally, it was the official start day of IMO.

The team leaders from each participating country will form a temporary topic selection committee to discuss and vote to decide on the day's test questions and the scoring rules for the test questions.

According to convention, the three daily questions of IMO should follow the principle from difficult to easy.

That is, questions 1 and 4 are the lowest in difficulty, questions 2 and 5 are in medium difficulty, and questions 3 and 6 are difficult!

Especially for the sixth question, in every IMO, only a handful of players can solve this question.

Gu Lu, wearing a team uniform with the Chinese flag printed on the chest, opened the door and walked into the conference room.

Countless eyes turned to look over, and Gu Lu nodded and smiled at everyone.

Everyone also nodded and showed kind smiles.

After all, the Chinese team is also a superpower in the IMO arena.

In more than ten years of participating in the competition, I have never fallen out of the top three positions in the group.

They are a small group of cannon fodder countries, with more than a dozen national team leaders added together. At the IMO topic selection meeting, they may not even have the right to speak at the National People's Congress.

Gu Lu found the seat with the Chinese national team label and sat down.

As soon as I put the notebook on the table, I heard an inexplicable voice coming from the side, "Oh, Gu Lu, it really is you."

Gu Lu turned his head and saw an obviously Asian face, but the facial features were more compact.

"Who are you?" Gu Luqing frowned.

From the tone of his voice, he must not be his friend.

The man's face turned dark, obviously angry that Gu Lu didn't remember him.

He pointed to the Korean flag on his chest and reminded, "2011, IMO competition!"

"Oh oh oh, it's you." Gu Lu found this figure in his vague memory.

It should have been when he participated in the IMO in his freshman year of high school. At that time, there was a member of the Korean team who seemed to be the person in front of him when he was young.

I vaguely remember that at that time, this person seemed to have won the only gold medal of the Korean team that year, with a score of 36 points.

Gu Lu scored 42 points that year, a perfect score.

"Excuse me, your name is...?" Gu Lu said with a smile, "I'm sorry, I have too many defeated generals, so I don't have the habit of remembering their names one by one."

The Korean team leader's face became even more gloomy. After being silent for a long time, he gritted his teeth and slowly said his name, "????."

Gu Lu's face looked a little strange.

????, if this name is translated into Chinese, it is - Pu Changqu!

Logically speaking, such a distinctive name should have left a particularly deep impression on me back then.

Gu Lu looked at Park Changqu's neck. The sign hanging on his neck was the leader of the Korean team.

"So, Leader Park, you want to rekindle old friendship with me?" Gu Lu said with a smile.

Reminiscing about old friendships?

Pu Changqu sneered in his heart.

He and Gu Lu had no old friendship to talk about.

Because all Gu Lu gave him was humiliation and unwillingness!

The 2011 IMO competition is known as the most difficult test question in history.

Park Changqu tried his best that year, but only scored 36 points.

But something happened that year.

Gu Lu stood out and became the only one with a perfect score in the IMO that year.

During the exam, Park Changqu sat behind Gu Lu.

Therefore, Gu Lun's behavior of answering the questions easily and casually, handing in the papers and leaving an hour in advance, greatly shocked the young Park Changqu at the time.

Especially when I learned that Gu Lu was the only one with perfect scores in the audience, I had no admiration for Gu Lu or Park Changqu, only humiliation and unwillingness.

The feeling of being completely crushed made Park Changqu, who had always been proud of his talents, almost collapse.

Park Changqu is not so confident that he thinks he is the strongest mathematical genius in the IMO competition, but at least Park Changqu feels that the gap between him and the top few is not very big, only one or two points at most.

But the facts gave Park Changqu a critical blow.

6 points is close to the score for a question, and the difficulty of the question back then was comparable to hell.

Even the organizing committee did not expect that there would really be perfect scores.

When he found out that Dao Gu Lu was just a freshman in high school in China, Pu Changqu was completely autistic.

Humiliation and unwillingness suddenly filled his heart.

The pride of being a strong man was shattered by Gu Lu.

At that time, he secretly made up his mind to defeat Gu Lu.

Even if...it's only once.

Unfortunately, he no longer has this opportunity.

This is his third time participating in IMO. After this time, he will graduate and enter his college career.
