Chapter 202

On February 22, at 9 o'clock in the morning of Yanjing time, the 18th American Global Collegiate Mathematical Contest in Modeling officially started!

This year was the largest number of participants in the event's history.

More than 27,000 teams from 18 countries and regions around the world participated in the competition.

Except for the fact that the competition lasts for half a day longer and the language of the modeling paper must be English, the other rules are no different from the national competition.

At eight o'clock in the morning, Bi Qi and his party came to the computer room early.

Then, while eating breakfast, I waited with the other teams in the computer room for the opening of the question download channel.

This was Bizzie's first time participating in an official modeling competition, and he was a little nervous.

He clenched his hands and stared at the computer screen in front of him without blinking, waiting for the competition to begin.

…………

At nine o'clock in Yanjing time, the modeling questions will be downloaded from the major official websites.

There are a total of six modeling questions in Meisai, and one of them is selected to answer. Each question has a fixed focus.

Question A, continuous.

Question B, discrete type.

Question C, Big Data.

Question D, Operations Research/Network Science.

Question E, Environmental Science.

Question F, Policy.

If you choose one of the questions A, B, or C, you will participate in the MCM (Mathematitest In Modeling) competition by default.

If you choose D, E, and F, you will participate in the Iterdisary Modeling and Interdisciplinary Modeling Competition.

If you insist on the difference between MCM and ICM, the general MCM competition topics are more specific, concise and clear.

ICM competitions, on the other hand, are more open-ended, "bigger", more macroscopic, and longer, and tend to be of common concern on a global scale, so they generally do not rely on specific cultural backgrounds or lifestyle habits.

A considerable part of the MCM questions are based on the background of life in the United States, which is not familiar to participants from other countries, especially China.

Therefore, in most cases, Chinese participants will choose one of the questions D, E, and F to answer, that is, to participate in the ICM competition!

Of course, the most important thing is to look at the area that the team is good at, and this view cannot be taken as a definitive opinion.

"It's time to start downloading questions!"

Beside him, a voice from teammate Zhao Liang came.

"Hurry up, hurry up!"

Another teammate, Fang Yunlong, stood behind Zhao Liang and urged.

They only had eighty-four hours in total, and time was money to them.

There are less than 10 trillion questions in total, and even if there are many people downloading them at the same time, they are downloaded quickly.

Bi Qi moved his chair and leaned over, and the three of them looked at the computer screen together, carefully browsing each question.

Question A, about the propagation of radio electromagnetic waves.

Question B, the question of language type.

Question C, energy production issues.

Question D, the question of gasoline vehicles and electric vehicles.

Question E, climate change issues.

Question F, the cost of privacy.

The three of them spent more than ten minutes to read all the six questions.

At the same time, Bi Qi already had a general idea in his heart.

First of all, questions C and F are definitely not available.

The content of question C is to let people develop a feasible energy contract for a specific region through the analysis and modeling of a certain amount of data, so as to increase the use of clean energy and renewable energy.

And this specific region that was selected is located in the four states of the United States.

They are California, Arizona, New Mexico, and Texas.

That makes the question have a strong "American style".

The students of the United States may not know much about these four regions.

But for a Chinese contestant like Biqi, it's very unfriendly.

Since I don't know about it, I am afraid that it will be a lot of time just to investigate the situation in these four states and check the relevant information

THEREFORE, BIQI WAS THE FIRST TO PASS THIS QUESTION.

As for not choosing question F, the reason is even simpler.

There are five questions in the first ABCDE, and each question has only three or four questions.

And the F question, there are a whole eight questions!

Eight questions!

Twice as many as other topics.

Moreover, the difficulty of each question is not easy.

Unless they actively want to increase the difficulty of the challenge, Bizzie estimates that few people will choose the F question.

Next, it's a matter of choosing one of the four.

"Which one shall we choose?" Bi Qi asked softly after glancing at his two teammates.

The two teammates glanced at each other and said in unison, "Bi Qi, you choose!"

Bizzie is responsible for modeling.

At the same time, it is the most important part of the whole set of tasks.

It is especially important to choose a suitable topic.

Chen Liang, who is in charge of programming, and Fang Yunlong, who writes papers, do not have so many requirements for topics.

Bi Qi nodded, then touched his chin and muttered for a few seconds, and said in a firm tone, "Let's choose question A!"

Question A is a question about the propagation of electromagnetic waves.

It's more of a physics problem than a modeling problem.

Most modeling problems require a lot of data support.

And these data need to be obtained by constantly consulting the literature, which is quite troublesome and a waste of time.

However, question A is different, and very little data is needed to solve this problem.

More importantly, it is the derivation of the formula.

There are three questions in question A, all of which can be derived from formulas.

As a mathematics student, isn't deriving formulas what he does best?

Moreover, physics is also Bizzie's strong point.

As early as last summer, Bi Qi had already completed the course of college physics.

"Question A?" Hearing Bi Qi's choice, the two teammates were stunned for a moment.

The difficulty of the question A is clear to both of them.

Once the formula can be derived, then all is well.

But if it can't be deduced, then the follow-up work can't be carried out at all.

It can be said that once this question is chosen, all the burden is on Bi Qi, who is responsible for modeling.

"Bi Qi, have you decided?" Chen Liang hesitated for a moment and opened his mouth to confirm.

"I've decided!" Bi Qi nodded heavily, "Trust me!"

Changing the topic halfway is a big taboo among the taboos.

Therefore, under normal circumstances, which topic is chosen at the beginning, no matter what the follow-up is, it will go all the way to the black.

The selection of topics is quite important, and it needs to be cautious and cautious.

Many teams do not hesitate to waste two or three hours of time on topic selection, which is also the reason.

Zhao Liang patted Bi Qi's shoulder, "I believe you!"

Fang Yunlong nodded beside him, "Me too!"

The three of them were already tied to a chariot, and if they still didn't trust each other at this time, it would be better to just abandon the race.

Bi Qi nodded, then sat down in front of the computer, took out the prepared scratch paper and pen, and entered the competition mode.

He quickly calmed down, carefully skimmed through the questions again, and analyzed the problem according to the ideas taught by Gu Lu.

It was only after half an hour that Bi Qi began to put pen to paper on scratch paper.
