Chapter 200

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

Therefore, Bi Qi and two other classmates 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 a pair of dark circles under their eyes that were darker than pandas.

Although his expression was full of exhaustion, there was still an unconcealed look of excitement in his eyes.

This actual combat training is not useless after all.

At the very least, in terms of understanding team cooperation and mathematical modeling, the three of them have improved much better than they did four days ago.

"I'm going back to sleep, what about you?" said Billy, yawning heavily, and asked the two next to him.

The two people next to him spoke in unison, "Sleep!"

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

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

By the time Bizzy 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 he saw someone calling.

The caller was a teammate of Biqi's modeling team, Chen Liang.

"Ah Liang, what's the matter?" asked Bi Qi.

"Bi Qi, just now, the schedule of Meisai has come out!" Chen Liang replied, without the slightest excitement in his tone.

Bi Qi realized that something was wrong, and hurriedly asked, "When does Meisai start, and when is it?"

Chen Liang on the opposite side was silent for a few seconds, and then slowly spit out a few words, "The start time of the Meisai is set for February 27th, that is, ...... Chinese New Year's Eve!"

Bizzie: "......"

Chinese New Year's Eve?!

Bi Qi put down his phone and sat on the chair with a lot of pain.

Sure enough, the most tragic situation happened.

Bi Qi has long been worried that the time of this year's American competition will collide with the Spring Festival.

But I didn't expect it to be so coincidentally bumped into!

And it's still a dead hit.

The Chinese New Year's Eve Championship began, and the competition lasted for four days and three nights.

That means not only Chinese New Year's Eve, but even the first and second days of the new year, and they have to stay in the computer room.

Others celebrate the festival with big fish and meat in the bustling home, and they stay up all night programming instant noodles and steamed buns in the cold computer room.

It's so miserable!

But the matter is already doomed, and everyone can't change anything, so they can only pretend to be strong.

"Hey, didn't it just happen to hit the New Year, nothing serious. When the competition is over, I invite you and Yun Fei to go down to the restaurant, it will definitely be more abundant than the Chinese New Year's Eve dinner!"

Bi Qi pretended not to care, then hung up the phone, and leaned back in his chair as if he were 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 class changed from two sessions a week to one session a day.

Tonight, Gu Lu just walked into the classroom, and what he saw was the bitter and hateful faces of the students.

It's normal for people to have such expressions.

The time of the American race coincides with the time of the Chinese New Year, and no one will be happy.

Gu Lu put the book on the lectern and glanced at the people in the lecture hall with a smile, "Between the lectures, I will tell you one thing." ”

"The start time of the competition has come out, and everyone must know this. ”

"The time is February 27th, the day of the Chinese New Year's Eve. ”

Everyone nodded in unison.

"What I'm going to say today is that it has to do with the start time of the American Championship. Gu Lu smiled and spoke.

Gu Lu's words made the students below stunned.

Then, many students looked expectant.

Could it be that there is still a turning point in this matter?

Gu Lu didn't sell it, and said directly to everyone, "Presumably everyone is not satisfied with this competition time, our school has also actively listened to everyone's opinions, and has negotiated with many universities in the United States and the organizer of the American competition, that is, the United States Mathematics and its Application Federation." As a result of the final negotiations, the organizers of the competition were willing to move forward the start time by five days. ”

"Therefore, the revised time of the American game is from 9 a.m. on February 22 to 9 p.m. on February 25!"

Gu Lu's words fell, and there were successive cheers in the classroom.

Although the start of the game was five days earlier than the original one, they lost five days of preparation time.

But you don't have to rush to participate in the Chinese New Year, which is a great thing for everyone.

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

Gu Lu got the news an hour ago.

To be honest, Gu Lu was still a little incredulous after learning the news just now.

Meisai is an international mathematical modeling competition, Gu Lu did not expect that the United States Federation of Mathematics and Application really listened to the opinions of Chinese universities and advanced the start of the competition by five days.

But if you think about it carefully, Gu Lu will know the reason.

A few years ago, the organizers of the U.S. competition might not have listened to Huaguo's opinion.

After all, there are more than a dozen participating countries in the US competition, so you can't just accommodate you as one country.

But now it's different.

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

Even the organizer of the event, the United States, is also unable to 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 competition.

And the team of Huaguo occupies 5,000 of them.

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

In this way, it is not impossible to get the organizers of the American competition to back down and change the start time.

…………

The U.S. race was five days ahead of schedule, and in short, there were good and bad things.

Everyone can go home to catch up with the Chinese New Year after the competition, but it also means that there are five fewer days to prepare.

Time is getting a little tight.

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

"The content of this lesson is to tell you about several modeling methods, and what kind of problems are used in which methods, there are rules at all. ”

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

"Proportional analysis is the most basic and commonly used method to establish the functional relationship between variables. Algebraic methods are the main methods for solving discrete problems, such as discrete data, symbols, and graphs. There is also regression analysis, which is used to determine the expression of a function based on a set of observations of the function f (x), which is called a mathematical statistical method because it deals with static, independent data. ”

"Ordinary differential equations are used to solve the law of change between two variables, and the key is to establish the expression "instantaneous rate of change". Partial differential equations, on the other hand, are the laws of change between the dependent variable and two or more independent variables, and there are ......"

Gu Lu's talk is mainly for those students who are responsible for modeling work.

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

Mathematical modeling, in the final analysis, is a team effort.

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

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

For the remaining 20 days, just let them understand each other's workflows clearly.

Thinking like this in his heart, Gu Lu wiped the blackboard and talked about some of the skills needed to be used in writing papers.
