Chapter 64

At one o'clock in the afternoon, the first day of the IMO competition began.

The time to answer the questions is four and a half hours.

There is no intermission, but early submissions are permitted.

At around 12:40 p.m., students from all over the world had arrived at the venue.

Under the arrangement of the organizing committee, the students found their respective seats in the venue and sat down.

On the second floor, in the lounge, the leaders of various countries gathered here.

On the wall of the lounge, there is a large monitoring screen, which can see the every move of each player in the venue.

Originally, after the candidates entered, the team leaders were free to move.

Go back to your hotel to rest or relax off-campus.

But no one left.

Everyone stayed in the lounge, drinking coffee, their eyes scanning the surveillance screen from time to time.

Most of the coaches were even more nervous than the students below.

As the saying goes, the ignorant are fearless.

Most of the more than 600 IMO candidates are participating in the IMO competition for the first time.

There is still too little understanding of the cruelty of IMO.

Here, however, there are some of the world's top mathematical geniuses.

Which one is not selected after layers of screening, one out of ten thousand, or even one out of million.

Each and every one of us has a limit to what we can achieve in the future.

In the world, perhaps only in the IMO arena will you see so many of the world's top talents competing on the same stage.

In the lounge, Gu Lu leaned comfortably on the sofa and leisurely swiped his mobile phone.

Next to him was Team Leader Park Changqu, who had just squeezed in.

He leaned forward at this time, his nervous palms were already full of sweat, but he still forced his composure to put his hands on his knees, licked his dry lips, and stared at the six members of the Korean team on the monitoring screen.

In the venue, the candidates have been done in order.

This order is based on the rankings of the previous IMO Team Competition.

In the middle of the first row, sat six members of the Korean team, the champion of the previous year.

On the left, there are six members of the Mi Guo team, which won the second place in the group last time, and on the right, there are six members of the Hua Guo team, which ranked third last time.

Bi Qi is Ma Zhengxuan on his right, and on his left is a member of the Korean team.

In the surveillance, it can be seen that after Bi Qi sat down, he looked restlessly left and right.

"Zhengxuan, are you nervous?" asked Bi Qi in a low voice.

"Not nervous. ”

"But...... I'm nervous!"

"Take a deep breath, suck as much as you want!"

More than ten seconds later.

Ma Zhengxuan: "Are you still nervous?"

Biqi: "I'm not nervous, but I'm a little hypoxic and dizzy." ”

Ma Zhengxuan: "......"

Bi Qi finally came to his senses, feeling that someone was looking at him, he turned his head and met the eyes of the Korean team player next to him.

The South Korean team member wore gold-rimmed glasses, tall and thin.

He smiled at Bi Qiwei and said in broken Chinese, "Hello ......"

Bi Qi nodded, smiled in return, and then greeted quietly,

"Savadica!"

South Korea: "???"

There's no way, he can't speak Korean.

In Japanese, he can barely say a few words with years of accumulation of watching movies.

But Korean films are not his favorite genre, so he doesn't know anything about it at all.

I only hope that this international lingua franca can be understood by this Korean.

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

At 12:57, the invigilator distributed the test paper and scratch paper.

Candidates are allowed to bring paper books for the IMO exam.

In Chinese terms, it is an open-book exam.

But the subject of mathematics ......

Anyone who has experienced it knows that open books are of little use for mathematics.

The question of whether it should be, or not.

On the contrary, it will waste too much unnecessary time by consulting books.

So Bi Qi went straight to battle lightly.

I didn't bring anything extra except stationery.

At one o'clock, the exam begins.

An English announcement came from the venue, "Candidates, please pay attention, the exam has officially begun, please start answering the exam, please start answering!"

Whew!

Hundreds of people started writing at the same time, and they began to solve the three problems on the test paper.

At the same time, in the lounge, several coaches stared at the monitoring screen, and they all stood up nervously.

"But you have to hold it steady!"

The team leaders shouted in their hearts.

Pu Changqu glanced at the calm group of Gu Lu beside him, forcibly suppressed the tension in his heart, squeezed out a smile and asked, "Team Leader Gu, don't you want to take a look at the state of your team members?"

"There's no need. Gu Lu replied lightly.

Even if you look at it, you can't do anything but worry.

Park Changqu spoke, "Leader Gu, the bet I mentioned earlier ......"

Although the plane geometry question, which was far beyond the IMO level, was selected into the three questions, Na Pu Changqu was not too worried.

Anyway, everyone wants to make that question.

That's direct, just take this year's IMO as a full score of only 36 points.

For the strength of the six members of the South Korean team, Park Changqu has strong self-confidence.

Therefore, he had the idea of competing with Gu Lu again.

In terms of personal mathematics, Park Changqu has been hit by Gu Lu without any belief in competition.

But since both of them are team leaders, the performance of the players is also closely related to them.

He wanted to defeat Gu Lu in this regard.

But Gu Lu's answer was decisive again, "Don't bet." ”

Park Changqu: "......"

Big brother, can't you just say yes?

I'll give you the money!

I just want to enjoy the thrill of winning you, is it that hard?

I've been waiting six years for that moment!

No matter!

Pu Changqu gritted his teeth and pretended not to hear clearly, "What, it's a gamble!" Coach Gu, this is what you said personally, you must not go back!"

"I'll give you the money, three hundred dollars!"

Pu Changqu took out three hundred dollars from his pocket and slapped it in front of Gu Lu.

Then he quickly put it in his pocket, "The bet is done! ”

Gu Lu who watched Park Changqu's performance throughout the whole process: "......"

This guy, the operation is too sassy!

completely caught Gu Lu off guard.

He's ...... Forced to participate in a gambling contract?

But I didn't do anything, I didn't do anything?

Gu Lu turned his head to look at Pu Changqu, who was smiling, and his face was speechless.

There is nothing to lose if you lose, and you earn $600 for nothing.

Who does Gu Lu find to reason with this matter?

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

In the venue, the exam has been going on for five minutes.

Most people are still in the process of skimming through the test questions.

After all, it is very necessary to distinguish the difficulty of the three questions and allocate the exam time reasonably in the IMO arena.

"It's comfortable!"

After reading the three questions, Bi Qi couldn't help but groan.

The three questions were much simpler than he thought.

Especially the second question.

Among the practice questions given to them by Gu Lu before, there was a somewhat similar question.

At that time, Bi Qi was stunned to watch Gu Lu use the Lagrange multiplier method, and he used a whole day to write more than 50 lines of formulas to solve the problem, and it was easy to solve it with only ten lines of formulas.

So Bizzy is very fond of this Lagrange multiplier.

As a result, at the first glance of the second question, Bizzy thought of the concept of Lagrange multiplier.

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

PS: uh...... The recommendation vote ranking is currently 301, which is one place short.

Brothers, meet me!
