A few days later, it was time for the National Mathematical Contest in Modeling.

The tournament lasted for 72 hours.

Tang Yan and other contestants took the school bus a day in advance and came to the dormitory specially arranged by the school.

For a four-night stay, toiletries and clothes are indispensable.

Tang Yan participated in the mathematical modeling competition in the last small world and is very experienced in this.

She not only prepared just enough clothes and toiletries for a change of clothes, but also prepared two sets of disposable sheets and quilt covers, and gave Liu Yizi a set.

Liu Yizi looked at the bedding on the dormitory, and the bedding prepared by the school was dirty, so she was very grateful to take the things that Tang Yan had prepared for her.

"You're the thigh on our team! These logistical matters should be prepared by He Yang and me, and you shouldn't have to worry about them! ”

Tang Yan saw Liu Yizi's dimples looming as she spoke, and she wanted to poke her fingers very much.

She restrained her fingers and smiled.

"I've done so much, how can you repay me?"

Liu Yizi grinned: "The little woman has nothing to repay, she can only promise herself." ”

Tang Yan smiled evilly: "Then uncle, I'm welcome." ”

After speaking, he stretched out his finger and poked Liu Yizi's dimple with satisfaction.

Well... It turned out to be such a feel.

Liu Yizi snorted, and began to fight back without claws, and the two girls laughed together.

When everyone was almost cleaned up, the school teacher gathered everyone together to give a pre-game lecture.

There is nothing new in the content of the lecture, it is just to talk about the rules and tell everyone not to cheat.

In fact, it is too easy to cheat in the mathematical modeling competition.

Even in some bad schools, tutors will take the initiative to help students with questions.

However, the topics of the National College Student Mathematical Contest in Modeling have always covered a wide range of topics and are very difficult. In a normal school, there are not necessarily more teachers than the student union.

It's easy to cheat, but it's hard to get useful ideas or answers after cheating.

After the teacher finished speaking, he let everyone disperse, go back to rest, and arrive at the computer room on time tomorrow.

Tang Yan's five senses were keen, and on the way back to the dormitory with Liu Yizi hand in arm, he felt that someone behind him was looking at here from time to time.

She looked behind her with her peripheral vision.

I saw a boy holding the hand of a beautiful girl, and looked at her from time to time.

This beautiful girl has exquisite makeup and fashionable clothes, and Tang Yan doesn't know her.

But the boy next to this girl, Tang Yan knows.

It was Wang Xiang, a junior in the Department of Mathematics.

The stupid beep who said that it was difficult for girls to make achievements in mathematics, let Tang Yan be his girlfriend, and he took Tang Yan to win the second national award.

Tang Yan retracted his afterglow.

Don't waste your precious time looking at silly beeps.

Soon, it was the day of the second day of the official competition.

Liu Yizi got up early in the morning and bought breakfast for Tang Yan.

To Tang Yan's surprise.

Liu Yizi only brought breakfast for herself, but she didn't have He Yang's share.

However, He Yang also consciously finished eating breakfast before arriving at the computer room.

At about 7:30, the computer room was full of people, and almost everyone arrived.

According to the official data, there are nearly 26,000 teams and more than 80,000 college students participating in this competition.

When the bell rings at 8:00, more than 80,000 people across the country will open the website at the same time to download the exam questions.

The three members of Tang Yan's team were no exception, and they quickly downloaded the questions as soon as the bell rang.

There are two questions in the undergraduate exam: AB.

A team only needs to choose one of the two questions to do.

Someone read the question.

"Question A, furnace temperature curve. In the production of electronic products such as integrated circuit boards...... Question B, Crossing the Desert ......"

Suddenly, everyone was dumbfounded.

"! What the hell is this? ”

"What the hell is this year's topic?"

"Why cross the desert? Isn't it okay to stay at home? ”

"Damn,! I also read the question of furnace temperature curve the day before yesterday, but it is not at all similar to this question! ”

"Big guy, you are the number one, think of a way!"

There was a chaotic sound in the computer room.

Most people are helpless and don't know what to do.

But there are definitely cattle too.

For example, Wang Xiang.

Although this man is a bit of garbage, his math ability is really good.

In addition, in Wang Xiang's team, the person in charge of programming is also a great god, and the two have begun to allocate work in a negotiated manner.

And the last person in Wang Xiang's team was the beautiful girl she was holding yesterday, and she should be in charge of the paper.

Another example is next door to Tang Yan's team, who is in charge of mathematical modeling, a senior academic god with a younger brother, who has already selected a topic and started to do it.

The choice of two questions in AB should be controlled within half an hour as much as possible.

Tang Yan didn't make a choice here.

He Yang was a little worried: "What's the matter, is it too difficult?" ”

Tang Yan looked at He Yang and asked very seriously: "Which of these two questions do you think is more difficult?" ”

He Yang suddenly collapsed: "Big guy! You don't have to be programmer and forget all the math! Can't you tell which question is difficult? ”

Tang Yan spread his hands innocently: "I think the two questions are super simple, and I really can't tell the difference." ”

She graduated with a Ph.D. in the last small world.

Doing these questions is equivalent to asking a college student to distinguish which of the two questions of a junior high school student is difficult.

The answer is definitely not difficult.

He Yang: "......"

I believe you're a ghost!

I didn't look at the few teams nearby, they scratched their ears and cheeks, and several hairs fell out.

Tang Yan sighed.

She is telling the truth, why not believe it?

Generally, if you do the relatively difficult question, the score will be higher, and she wants to choose the difficult one.

He Yang, an idiot, couldn't tell whether Tang Yan was pretending to be a beep or really not, and he didn't mention any opinions, so he couldn't count on it at all.

At the critical moment, we still have to look at Liu Yizi, a little clever ghost.

I saw Liu Yizi walking around the computer room, and came back and told Tang Yan: "I think there are more people who choose question A, maybe question B is more difficult." ”

The difficulty of the two questions is indeed not much different, so Tang Yan can't tell the difference.

However, everyone has usually come into contact with the problem of furnace temperature curve, and the problem of crossing the desert is a bit off. So for others, question A can be a little easier.

Once you've chosen your topic, the rest is easy.

It took Tang Yan three hours to build the mathematical modeling.

He Yang was stunned on the sidelines.

Generally, the players in charge of mathematical modeling have to stay up until at least midnight today, or even tomorrow, why is Tang Yan so fast?

Tang Yan glanced at He Yang who was in a daze: "What are you in a daze?" Let's go, let's eat! Come back and give you two ideas, write your essay now. ”

The general thesis is the 3rd day.

But Tang Yan wanted to buy more time for the two teammates, so that they could finish the first draft of the paper earlier, so that she had time to refine it finally.

He Yang woke up like a dream.

At this moment, he seemed to see the National One Award beckoning to him.

"Great God! How can you go to eat in person? The little ones are running errands for you to bring back. ”

He Yang was rarely clever, and finally found his position.

In fact, their team is a configuration of one god with two pits, and he has to catch up the logistics work in this pit!
