Chapter 326 Difficulty in choosing

Silent all night.

The next day, September 9, the Mathematical Modeling Contest was held as scheduled.

This year is the 20th year that the National Undergraduate Mathematical Contest in Modeling has been held, and the number of participants is also increasing year by year.

而今年的建模大赛，更是有来自全国34个省/市/区(包括香港、澳门和台湾)及新加坡和澳大利亚的1418所院校/校区、36375个队（本科33062队、专科3313队）、近11万名大学生报名参加本项竞赛。

With such a scale and number of participants, it is not without reason that this event is called "the largest basic subject competition in colleges and universities in the country".

This year, Tsinghua University has a total of 210 people and 70 teams participating in the modeling competition, covering almost all colleges and grades.

Cheng Nuo, Liu Qing, and Gu Feifei were one of them.

The venue of the competition is several computer rooms specially vacated by the school, but it is allowed to bring and use their own equipment.

Anyway, there is no answer to things like mathematical modeling on the Internet, so I can only rely on myself, or... hug my thighs!

At around 07:30 in the morning, after breakfast, Cheng Nuo met the two girls downstairs in the modeling competition venue.

"Hi, good morning!" Cheng Nuo waved to the two girls with a smile while holding a straw of milk tea in his mouth.

"Master, it's getting late, the other teams have already arrived at the competition venue and are ready to go!" Seeing Cheng Nuo's leisurely look, the two women were not in a hurry, they grabbed Cheng Nuo's hand and hurried away Go upstairs, "God, let's hurry up too, let's make some preparations earlier!"

"Then let's go up!" Cheng Nuo took the last sip of the milk tea, and while being dragged up by the two women, he casually threw the paper cup into the trash can downstairs.

On the way upstairs, Cheng Nuo smiled and said, "Actually, we don't need to be so anxious at all. Isn't the downloading of the topic starting at eight o'clock? Besides, even if the channel for downloading the topic has already been opened, we can relax."

"72 hours is enough!"

…………

Cheng Nuo and his team's competition classroom is in 203.

Pushing the door open, the classroom was almost full of people. When they heard the door opening, most of them looked up at the door.

When they saw Cheng Nuo and the three standing at the door, many of them showed strange expressions.

Two girls!

Logically speaking, almost [-]% of the students who came to participate in the modeling competition were boys.And it does have to be admitted that in mathematics, boys have an advantage over girls.

Generally speaking, it is rare for a three-person modeling team to have a girl contestant.

But seeing the team at the door, there are one man and two women, which is really rare.

But everyone was just surprised for a while, then lowered their heads, each minding their own business.

Maybe it just happened that two girls who are good at modeling got together in the same team.

With this in mind, they stopped paying attention to Cheng Nuo and the others.

And Cheng Nuo, Liu Qing, and Gu Feifei found a place in the computer room.

Cheng Nuo took off his backpack and took out his laptop.

Where are the two sisters Liu Qing and Gu Feifei?

It's nice to have a bag on your back, but it's not a laptop you need for modeling, it's... a bag full of snacks!

That's right, snacks!
Cheng Nuo told the two of them last night that they don't need to bring their laptops to the competition venue. After all, they don't need to bring them with them, and it's a waste of time to memorize them. It's better to bring some practical things.

So, the two girls filled their schoolbags with slow-moving snacks, including peanuts, melon seeds, mineral water and so on.

If they didn't know that there were seats in the classroom, they would have almost brought the small bench!

Prepare to be one, oh no, two real people who eat melons!
"Master, would you like me some sunflower seeds?" Gu Qing cautiously asked Cheng Nuo who was sitting in front of the computer, waiting for the announcement of the contest questions.

"Let's have some." Anyway, there is no clear rule in the game computer room that no snacks are allowed, so it's boring to wait all this time.

Knock bang, click bang~~
The three of them ate with gusto.

There are still 10 minutes left before the announcement of the competition questions. Those contestants who held their breath, covered their hearts, and waited for the competition to start, naturally and clearly heard the sound of cracking melon seeds.

Following the sound, everyone looked at the three of them eating sunflower seeds happily.

Time passed by minute by minute.

At 2021 o'clock in Kyoto time, the test questions of the [-] Mathematical Contest in Modeling will be released on the official website of the National Undergraduate Mathematical Contest in Modeling, Huaguo College Students Online, Higher Education Press, Huaguo University Mathematical Modeling Course Center, Huaguo Mathematical Modeling and other websites.

Cheng Nuo logged in slowly and downloaded the test questions.

For questions A, B, C, and D, the undergraduate group can only choose one of A and B.

Cheng Nuo opened the file and read the test questions one by one.

[Question A: The impact of lane occupation on urban road capacity]

Lane occupancy refers to the phenomenon that the traffic capacity of a lane or road cross section decreases within a unit time due to factors such as traffic accidents, roadside parking, and road occupation construction.Since the city roads...

[Question B: Stitching and Restoration of Shredded Paper]

The splicing of broken documents has important applications in the fields of judicial evidence restoration, historical document restoration, and military intelligence acquisition.Traditionally, splicing and restoration work has been done manually...

It took about ten minutes for Cheng Nuo to read both questions A and B and their attachments.

The two girls, Liu Qing and Gu Feifei, also watched it with Cheng Nuo at the back.Although, they can't understand it.

"Master, which of these two questions is easier?" Liu Qing asked inquiringly.

Cheng Nuo shrugged, "There's no such thing as a difficult or easy modeling task, it just depends on which one suits you better."

"My God, which one should we choose?" This time it was Gu Feifei who spoke.

This question stopped Cheng Nuo a bit.

Because in his opinion, both questions are OK for him, and it doesn't matter which one he chooses.

Even though he has never dabbled in traffic management and forensic identification and the two fields, in the final analysis, mathematical modeling still transforms a problem in another field into a mathematical problem.

Same way!
Moreover, for the two questions, Cheng Nuo had already presented a modeling outline in his mind.

"My God, my God, what's wrong with you, are you feeling unwell?" Seeing Cheng Nuo in a daze for a long time, Liu Qing asked worriedly.

"No, I'm just wondering which question to choose. Hey, tell me, if we do both questions, will two national first prizes be awarded to us during the award ceremony?"

One prize for two countries, it's exciting to think about it!

"Uh... Great God, this seems to be impossible." Originally, Liu Qing thought that Cheng Nuo was struggling because the two questions were very difficult for him.

Unexpectedly, the thigh in front of my eyes is really too bold, I want to win the first prize of two countries at once!
"Huh? No way. Well then, let's choose question B. I hope more people will choose this question." Cheng Nuo said without interest.
