Chapter 200

The competition lasts for four days and three nights, a total of 84 hours.

Therefore, Bi Qi and two other students from the same team stayed in the computer room for a full eighty-four hours.

Eighty-four hours later.

Bi Qi and the three of them walked out of the computer room with dark circles under their eyes that were darker than those of pandas.

Although his expression was full of exhaustion, there was still a look of excitement that could not be hidden in his eyes.

This practical training is not useless after all.

At least, the three Bi Qi's understanding of team cooperation and mathematical modeling has improved much compared to four days ago.

"I'm going back to sleep, where are you?" Bi Qi asked the two people next to her with a big yawn.

The two people next to them said at the same time, "Sleep!"

Back at the dormitory, Cai Kunxu had gone home early, and Bi Qi was the only one left in the dormitory.

Bi Qi, who had only slept less than ten hours in four days and three nights, climbed into bed in a daze and fell into a deep sleep without even taking off his clothes.

When Bi Qi woke up again, it was already twelve hours later.

Bi Qi got up, washed up, and was just about to go to the cafeteria to eat when she saw someone calling.

The caller was Chen Liang, a teammate of Biqi Modeling Team.

"A Liang, what's the matter?" Bi Qi asked through the phone.

"Biqi, just now, the schedule for the US competition was announced!" Chen Liang replied, without any excitement in his tone.

Bi Qi realized that something was wrong and hurriedly asked, "When will the US competition start? What is the specific time?"

Chen Liang, who was opposite him, was silent for a few seconds, then slowly uttered a few words, "The start time of the US competition is set for February 27th, which is... New Year's Eve!"

Bi Qi: "..."

New Year's Eve?!

Bi Qi put down the phone and sat on the chair in pain.

Sure enough, the most tragic situation happened.

Bi Qi has long been worried that this year's US competition will coincide with the Spring Festival.

But I didn’t expect that we would bump into each other by chance!

And it was still very hard to hit.

The American Games kicks off on New Year’s Eve and lasts for four days and three nights.

That means not only New Year's Eve, but also the first and second days of the Lunar New Year, you have to stay in the computer room hard.

Others are celebrating the festival in bustling homes with plenty of meat and fish, while they stay up all night programming in cold computer rooms with instant noodles and steamed buns.

It’s so miserable!

But things are doomed, and no one can change anything. They can only pretend to be strong and face it.

"Hey, it just happens to coincide with the Chinese New Year. It's no big deal. After the game is over, I'll treat you and Yunfei to a restaurant. It will definitely be more sumptuous than the New Year's Eve dinner!"

Bi Qi smiled pretending not to care, then hung up the phone and leaned back on the chair slumped.

…………

In the evening, it was Gu Lu’s modeling tutorial class.

After the exam week ended and the winter vacation began, Gu Lu’s modeling tutorial classes changed from two sessions per week to one session per day.

Tonight, when Gu Lu just walked into the classroom, what he saw were the faces of his classmates with hatred and hatred.

It's normal for people to have such expressions.

The US competition coincides with the Chinese New Year, so no one will be happy.

Gu Lu put the book on the desk and glanced at everyone in the lecture hall with a smile, "Before I start the lecture, I want to tell you something."

"The start time of the U.S. competition has been announced, and everyone must know this."

"The time is February 27th, New Year's Eve."

Everyone nodded in unison.

"What I want to talk about today is related to the start time of this US competition." Gu Lu said with a smile.

Gu Lu's words made the students below couldn't help but be stunned.

Then, many students looked expectant.

Could it be that there is still a chance for this matter to turn around?

Gu Lu did not show off, and directly spoke to everyone, "I think everyone is not satisfied with this competition time. Our school has also actively listened to everyone's opinions, and has cooperated with many universities in the country and the organizer of the competition, which is the American Mathematics Association.

and its application federation. The final result of the consultation was that the organizers of the US competition were willing to advance the start time by five days."

"Therefore, the revised US competition time is from 9 am on February 22 to 9 pm on February 25!"

After Gu Lu finished speaking, the classroom burst into cheers.

Although the game started five days earlier than originally scheduled, they lost five days of preparation time.

But you don’t have to rush to compete during the Chinese New Year, which is a great thing for everyone.

For Chinese people, celebrating the New Year has a special complex.

Gu Lu got the news an hour ago.

To be honest, Gu Lu was still a little unbelievable after hearing the news.

The American Mathematical Contest is an international mathematical modeling competition. Gu Lu did not expect that the American Federation of Mathematics and Applications would actually listen to the opinions of Chinese universities and advance the start time of the competition by five days.

But after thinking about it carefully, Gu Lu understood the reason.

A few years ago, the organizers of the US Games might not have listened to China’s opinions.

After all, there are more than a dozen participating countries in the US competition, so we can’t just accommodate your country, China.

But it's different now.

In recent years, China has steadily become the country with the most teams participating in the US competition.

Even the United States, the organizer of the event, cannot compete with China in terms of the number of participants.

Last year, a total of 20,000 teams from 17 countries and regions participated in the US competition.

The Chinese troops accounted for 5,000 of them.

This number of entries is enough for China to have the capital to bargain with the organizers of the US competition.

In this way, it is not impossible for the organizers of the American Games to give in and change the start time.

…………

The U.S. competition is moved up five days, which has both good and bad consequences.

Everyone can go home after the competition to catch up with the New Year, but it also means five days less time to prepare for the competition.

Time has become a bit tight.

In the modeling tutorial class, after Gu Lu announced the news, he went directly to the topic.

"The content of this class is to teach you several modeling methods. There are rules for what kind of methods to use for what kind of problems."

Gu Lu wrote a row of modeling methods on the blackboard and explained them one by one.

"The proportional analysis method is the most basic and commonly used method to establish functional relationships between variables. The algebraic method is the main method for solving discrete problems, such as discrete data, symbols, and graphics. There is also the regression analysis method, which is used to solve discrete problems.

A set of observed values ​​of function f (x) determines the expression of the function. Since it deals with static independent data, it is called a mathematical statistics method."

"Ordinary differential equations solve the change pattern between two variables, and the key is to establish the expression of the "instantaneous rate of change." And partial differential equations solve the change pattern between the dependent variable and two or more independent variables, and

…”

What Gu Lu said is mainly for the students who are responsible for modeling work.

But if the team members responsible for the other two tasks can understand it, that would be great.

Mathematical modeling, after all, is still a team effort.

As for the internal division of labor, there is no too strict division. The best situation is that three people in the team are good at modeling, programming, and thesis, and can divide the work flexibly.

But this situation rarely happens, and Gu Lu doesn't expect them to do this.

In the remaining twenty days, just let them understand each other's work processes clearly.
