Xueba's Black Technology Simulator

International Mathematical Olympiad (International Mathematical Olympiad) is referred to as IMO.

This competition is completely different from domestic ones.

There are more than a dozen questions in the domestic 2-hour test, mainly to test the comprehensive ability of the students and select 6 people to participate in the training.

Now it is divided into two days, with only three questions per day, and the time given is 4.5 hours.

It's hard to say which one is more difficult, after all, most of the questions in the national exam are actually based on IMO.

In IMO competitions, there is no team prize.

All are gold, silver, bronze, three awards.

The approximate ratio is 1:2:3, and about half of the people get nothing.

For those who don't get medals, scores are equally important.

Because with the increasing number of IMO competitions, it has risen to the point of comparing the national total scores.

Every time, everyone will evaluate the mathematics strength of primary and middle school students in a country based on the ranking of the total scores of the six contestants.

Xia Guo did a good job in this regard, hovering among the top few every year.

The most powerful are Xia Guo, Russia, the United States, Germany, and Romania, who basically take the championship in turn.

In the past decades, the Southern Baseball Country has never won a championship!

If Lu Xiao had paid attention to the news in his previous life, he would know that this year Nanbun finally broke the history of decades of failure and won the first IMO championship.

Not surprisingly now, there is still a high probability of getting the Nanbang.

Because they are "fully prepared".

After 7 o'clock in the morning, the members of Xia Guo's representative team and more than 60 to 70 other national teams had breakfast at the hotel.

After eating, we will go to different examination rooms of nearby schools for competitions.

The examination rooms for the 6 contestants will be separated.

While eating breakfast, Lu Xiao looked for an opportunity to massage the heads of Gu Rou and the little fat man, and said with a smile: "There are only 3 questions, and there are 4.5 hours left. Be confident, it will be absolutely fine."

The little fat man who was about to drink milk kept nodding, but Lu Xiao caught the milk shell out of the corner of his eye.

You must know that Lu Xiao's biggest golden finger, in addition to being able to simulate and solve problems, the most powerful thing is "photographic memory".

As long as you glance at it, the information has actually been recorded in your mind and can be retrieved at any time.

The simulator is also constantly taking all the data, and the simulation increases the experience of various disciplines.

In other words, even on the street, there are countless billboards.

The content of these advertisements was also recorded by Lu Xiao, and then fed to the simulator continuously to increase the experience in communication, advertising and other disciplines.

"Don't drink, fat!" Lu Xiao said seriously.

Yu Fei put down the milk obediently, and asked in confusion, "What's the matter, Master."

"Look at the shelf life." Lu Xiao said solemnly.

Boxed milk generally has a shelf life of six months, and each bottle of milk is stamped on the top or bottom to mark the time.

If you drink expired milk, then diarrhea is no joke.

"Ah, mine has expired for half a year!" Yu Fei said angrily after reading it.

Gu Rou is also drinking pure milk, mainly because the milk seems to be a sponsor of the event, and there are a lot of them in various places.

And it's Xiaguo milk!

There are Chinese characters on it, and many contestants in Xia Kingdom saw the familiar brand, and some took it directly.

"Hey, mine hasn't expired." Gu Rou asked doubtfully.

It does not appear to be the same batch of milk.

Lu Xiao looked at the time, frowned and said, "Give this expired box of milk to Mr. Liu. We don't have much time and we have to take the exam. Let the teachers investigate the responsibility, but I don't know how many people have been recruited."

Soon Lu Xiao and the others went to the school to take the exam, and Liu Yong handed over the expired milk to Ran Fei, the teacher who led the team.

After checking by them, it seems that only this box has a problem, and everything else is normal.

But no matter what, I still have to find trouble with the organizers.

If the child didn't find out just now, he would have already drunk this stuff.

Maybe if you have diarrhea during the test, how can you get a high score.

In order to get the ranking, Nan Bang has gone crazy.

Leaving aside accountability, Lu Xiao found his own examination room following the guidance of a part-time college student.

Then wait patiently for the question.

The annual IMO test questions are jointly issued by the main committee, and the chairman of the main committee is generally a mathematician from the host country.

The main committee is composed of teachers from various countries, plus well-known scholars.

The test questions must be translated into Chinese by the teacher who came over.

After all, this is an international competition, and more than dozens of languages ​​are used.

There is no need to worry about the confidentiality of the test questions. After so many sessions, a fixed process has been formed.

The exam papers were also translated early and sealed, and issued to each candidate soon.

Mathematics tests sometimes really look at talent.

Some questions, no matter how much time is given, can't be solved.

Although each question has 7 points, many people can't get a single point when the total score is 42 points.

Lu Xiao is obviously not such a person.

After "scanning" the question in a few seconds, he smiled.

Three questions, a total of 4.5 hours.

It is equivalent to 1.5 hours for each question, but Lu Xiao feels that he can write the answer in only half an hour.

He actually had no concept of the difficulty of the questions.

Anyway, no matter how difficult the question is, it is a paper tiger in front of the simulator.

Even lost the fun of doing the problem.

"It seems that there is no set time for handing in the papers. I can hand in the papers in advance. I might as well finish it and go back to the hotel. It's boring in the examination room." Lu Xiao looked at the frowning students from other countries.

There was a black classmate who stared wide-eyed at the topic.

It almost made Lu Xiao laugh.

It seems a bit difficult, if you wait for the little fat man and Gu Rou, it will probably take at least a few hours.

"Let's go, go, go back to the hotel and write code." Lu Xiao thought in his heart.

He didn't even bother to understand the questions. After all, some questions were convoluted, and it took a long time to understand.

In this case, simply do nothing.

Just follow the simulation answer given by the simulator.

But Lu Xiao didn't know that one of the three questions was super difficult!

It even reached the standard of being published in mathematics journals. If it can be proved perfectly, it will not be difficult to publish a paper.

This is a warning from the sponsor to the candidates.

It is also a question posed by the chairman of Nanbang himself. The students of Nanbangguo happen to have undergone special training and are not afraid of this kind of question.

It was difficult for other students to answer.

Regardless of the content of the assessment, it basically revolves around algebra, combinatorics, geometry, and number theory.

But the more basic it is, the more varied it is, and it can often form very complicated problems.

In the office where the main committee is located, the teachers are looking at this year's topic.

Many people only saw the complete test paper, which was kept secret before.

Some teachers with itchy hands immediately took out their pens and started to do it.

In 1988, it was the same. In the end, several number theory experts were slapped in the face, and they didn't even solve the legendary sixth question.

Instead, 7 out of 286 students did it and got full marks.

It’s hard to say there’s nothing tricky about it. At that time, An Nanguo’s Wu Baozhu got full marks, and later he won the Fields Medal, which should be his real strength.

But other things may not be so simple. Anyway, several students who made the problem are not famous at all.

"Xiba, what the hell is this? It's too difficult!" A Nanbang teacher complained himself.

However, some teachers in other countries secretly muttered that this kind of problem is also included. This is a super difficult problem that they want to imitate back then.

It is estimated that among more than 300 candidates, only six or seven can do it in the end.

There is a high probability that only 6 can be made, and they are all Nanban candidates.

When many people were thinking this way, a teacher suddenly ran in and shouted: "A student said to hand in the paper early! He's done!"

The teacher who was still working on the test paper just now lowered his head and saw that he had just finished a test paper that he could not answer, and fell into self-doubt.

Is it true that the test paper is not difficult, but my level has dropped too fast?

The students have started handing in papers!

Many people looked up at the office wall clock, it was only 28 minutes before the exam started!

This has broken history IMO.

No one has ever handed in the paper in 28 minutes of the 4.5 hour exam time.

Even a super genius would not do this after finishing the questions.

Do you want national honor!

I don't know how to check and check more, in case there is a mistake in the calculation.

Everyone stared at the teacher who reported the letter, wondering which country they were from, maybe they were blacks, but they were actually here to join in the fun.

Seeing that the question was too difficult, I just scribbled and didn't answer it.

Ask for support!
