Chapter 329: Choice Difficulties

Chapter 329
No words for a night.
The next day, September 12, the mathematical modeling contest was held as scheduled.
This year is already the twentieth year of the National University Student Mathematical Modeling Contest, and the number of participants has also increased year by year.
In this year’s modeling competition, there are 1,418 colleges/campus from 34 provinces/cities/regions across the country (including Hong Kong, Macau and Taiwan), Singapore and Australia, 36375 teams (33062 teams for undergraduates, 3313 teams for junior colleges). ), nearly 110,000 college students signed up to participate in this competition.
With such a scale and number of participants, this event is called "the largest basic subject competition in colleges and universities in the country", and it is not without reason.
This year, they have 210 people from Tsinghua University and 70 teams participated in the modeling competition, covering almost all colleges and grades.
Cheng Nuo, Liu Qing, and Gu Feifei are one of them.
The venue of the competition is a few computer rooms specially vacated by the school, but it is allowed to bring your own equipment.
Anyway, there is no answer for such things as mathematical modeling on the Internet. You can only rely on yourself, or...hold your thigh!
At around 7:30 in the morning, Cheng Nuo, who had finished breakfast, met the two girls downstairs in the modeling contest venue.
"Hey, morning!" Cheng Nuo held the straw of milk tea, smiled and waved to the two women.
"Great God, it's not early, the other teams have already arrived at the competition venue and ready to go!" Seeing Cheng Nuo's leisurely appearance, the two women are the emperor and the eunuch, so they took Cheng Nuo's hand and hurried away. Go upstairs, "Great God, let's go up too, do some preparations!"
"Then let's go up!" Cheng Nuo finished his last sip of the milk tea, while being dragged up by the two women, he threw the paper cup in the trash can downstairs.
On the way upstairs, Cheng Nuo smiled and said, "In fact, we don't need to worry about it. The download of the title does not start at 8 o'clock. Besides, even if the title download channel has been opened, we can relax."
"Seventy-two hours is enough!"
…………
Cheng Nuo and their group's competition classroom is at 203.
Pushing the door in, the classroom was almost full, and most of them looked up at the door when they heard the sound of pushing the door.
When they saw Cheng Nuo standing at the door, many of them showed different colors.
Two girls!
In theory, almost 80% of the students who come to participate in the modeling contest are boys. And I really have to admit that in mathematics, boys have an advantage over girls.
Generally, it is very rare for a team of three modeling to have a girl contestant.
But seeing the team at the door is one man and two women, which is really rare.
But everyone was astonished for a while, then bowed their heads, taking care of their own affairs.
Perhaps it just happened that two girls with good modeling skills got together in the same team.
Thinking of this in their hearts, they stopped paying attention to the three of Cheng Nuo.
And Cheng Nuo and 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 sisters Liu Qing and Gu Feifei?
It’s nice to have a bag on your back, but it’s not a laptop for modeling, but...a pack of snacks!
That's right, it's snacks!
Cheng Nuo explained to the two of them last night that they don't need to bring laptops or something to the competition venue. After all, they don't need to bring them. It was wasted so much effort to memorize them. It is better to bring some practical things.
As a result, the two girls stuffed their schoolbags with snacks that were slowly deceived, with peanuts, melon seeds, and mineral water in them.
If they hadn't known there were seats in the classroom, they would have almost brought the small bench!
Ready to be one, oh no, two real people who eat melons!
"Great God, do you want some melon seeds?" Gu Qing cautiously asked Cheng Nuo, who was sitting in front of the computer, waiting for the announcement of the competition question.
"Come on." Anyway, is there a written rule in the game machine room that you can't eat snacks? It just happens to be boring to wait like this.
Kab, kab
The three of them chatted with gusto.
In the last ten minutes before the announcement of the contest question, those contestants who held their breaths, covered their hearts, and waited for the start of the contest, naturally and clearly heard the sound of eating melon seeds.
Following the voice, everyone looked at the three people who were eating melon seeds with a speechless expression.
Time passed by every minute.
At 8 o'clock in Kyoto time, the 2021 Mathematical Modeling Contest questions will be published on the official website of the National College Student Mathematical Modeling Competition, Huaguo University Student Online, Higher Education Press, Huaguo College Mathematical Modeling Course Center, Huaguo Mathematical Modeling and other websites.
Cheng Nuo logged in slowly and downloaded the test questions.
There are four questions A, B, C, and D. The undergraduate group can only choose one of the two questions A and B.
Cheng Nuo opened the file and looked at the test questions one by one.
[Question A: The impact of occupied lanes on the capacity of urban roads]
Lane occupied refers to the phenomenon that the traffic capacity of the lane or the cross section of the road decreases within a unit time due to factors such as traffic accidents, roadside parking, and road occupation. Because of the city road...
[Question B: Splicing and restoration of shredded paper]
The splicing of broken documents has important applications in the restoration of judicial material evidence, restoration of historical documents, and acquisition of military intelligence. Traditionally, the splicing restoration work needs to be done manually...
After more than ten minutes, Cheng Nuo read the two questions A and B and their attachments.
The two women, Liu Qing and Gu Feifei, also watched with Cheng Nuo in the back. Although, they just don't understand.
"Great God, which of these two questions is easier?" Liu Qing asked inquiringly.
Cheng Nuo shrugged, "There is no difference between the difficulty and the easy of modeling, just see which one is more suitable for you."
"The great god, which one do we choose?" Gu Feifei was speaking this time.
This was a bit asked by Cheng Nuo.
Because in his opinion, both topics are OK for him, and it doesn't matter which one is chosen.
Even though he has not dabbled in traffic management and judicial appraisal and the two fields, in the final analysis, mathematical modeling still turns a problem in another field into a mathematical problem.
Different routes to the same end!
And ~EbookFREE.me~ For the two questions, Cheng Nuo has already presented a modeling outline in his mind at this time.
"Great God, Great God, what's wrong with you, is it uncomfortable?" Liu Qing asked worriedly after seeing Cheng Nuo dumbfounded for a long time.
"No, it's just that I'm struggling with which topic to choose. Hey, if we do both topics, will we be awarded two national first prizes when we award them?"
It’s exciting to think about the two national first prizes!
"Uh... Great God, this seems to be impossible." Originally, Liu Qing thought Cheng Nuo was struggling because the two topics were both difficult for him.
Unexpectedly, the thigh in front of me was so bold, I wanted to win two national first prizes at once!
"Huh? No. Okay, let's choose question B. I hope more people can choose this question." Cheng Nuo said with lack of interest.
