Chapter 109 Urgent Request for Foreign Aid (Yesterday's third update, please subscribe) Lu Shan looked up and felt that a fat boy with glasses who was silent next to him looked familiar. He seemed to be from the Applied Mathematics Class 2008, 1, and was his classmate. But Lu Shan couldn't remember the name. Who has time to remember a boy's name? "Brother Feng, I kind of regret signing up. Can you see if you can find other people? It seems like we can replace information before the competition starts." The door had just closed, and the somewhat irritable boy said, "When I sent the recruitment information, you were the one who contacted me first, and you also said that you were a math major and won the provincial third prize in the Mathematical Olympiad. The competition will start at 8:30 tomorrow morning. Now you tell me that you won't participate. Who can I go to with such a tight schedule?" On the contrary, the girl with short and delicate hair was more calm: "Since we have signed up for the competition, we should face it bravely. There is no way we can escape at the last minute." "You are a freshman, I am a sophomore, and Brother Feng is also a sophomore. Our purpose in participating in the Mathematical Modeling Competition this time is not necessarily to win a prize, but to accumulate experience and exercise our modeling thinking, which will be beneficial to our future studies and work." Wenfeng sat down on the chair and said, "Okay, let's stop talking about these discouraging things. Let's quickly choose the question type so that we won't panic when we draw the questions tomorrow." "For our undergraduate students, the questions we draw are divided into three categories: A, B, and C." "Type A questions are likely to involve physics, engineering and other issues, Type B questions may be physics, chemistry or operations research, and Type C questions are mainly about statistics, analysis and planning, etc."
"Let's analyze the majors of the three of us. Fan Bing, you majored in mathematics, Yu Chenxi, you majored in finance, and I majored in civil engineering. We are a good match, except that none of us majored in computer programming, so we may be a little worse." "But it doesn't matter. Mathematical modeling and programming are just a means. The most important thing is modeling." "So I suggest that we choose type A." "Type B questions will be very difficult for us to pass. Type C questions are relatively simple, but the competition is also fierce, so it will be difficult for us to stand out." "What's your opinion?" After hearing these words, Lu Shan burst out laughing. After all this time, the Mathematical Modeling Competition will be held tomorrow, and the morale of the three groups is still unstable. Some people even want to withdraw, not to mention how to divide the work. In fact, the Mathematical Modeling Competition for College Students is quite interesting. It can train students' thinking and increase team collaboration. Of course, everyone also values the prize money, which will make your future resume look better, and will be more popular with employers and teachers, etc. What is mathematical modeling? Take a simple mathematical modeling question of type C, which is closer to life, as an example: For example, a city has garbage, which can be landfilled or incinerated. If landfilled, the pollution will be less, but it will take a long time to decompose, and it will not generate economic value, and it will also occupy land. If incineration can be used to generate electricity, but it will pollute the environment. Then the question will give you a series of conditions such as the population of several cities and the amount of garbage generated, so that you can calculate the optimal layout of the garbage dump, etc. This requires you to use mathematical methods to establish a certain calculation model for such questions, and use programming methods to "implement" the calculation model, and at the same time write a paper on the above events. Although he was interested, Lu Shan didn't have the time to participate. Of course, the most important reason was that mathematical modeling was not challenging at all. This happened some time ago. Teacher Chen Liang invited Lu Shan to participate in the competition, but Lu Shan refused. Including just before dinner, Chen Liang called Lu Shan and persuaded Lu Shan to participate in the Mathematical Modeling Competition again. What this means is that Jiangzhou University, as a 211 and 985 university, is relatively famous in the country. However, in the annual high-quality college student competition such as the Mathematical Modeling Competition, its results are trampled under the feet of some key universities in coastal areas, which makes Jiangzhou University feel very embarrassed. Now that we have a mathematics genius like Lu Shan at Jiangzhou University, it would be a waste of talent if he doesn't win the national first prize and produce a high-quality modeling work. Yu Chenxi also felt that continuing to argue like this was definitely not a solution. She took out a few stacks of information from her bag and said, "These are real questions from the Mathematical Modeling Contest from a few years ago." "We have questions from all three types of test papers, A, B, and C." "Let's try each type of question to get a feel for it first, and then decide what to choose tomorrow." Yu Chenxi's step was very necessary. If he waited until all the test questions were out tomorrow before making his choice, on the one hand, he would not have enough time, and on the other hand, he would be caught off guard.
The three of them looked at volumes ABC respectively. Among them, paper C is the closest to life, but the competition is very fierce. To say it is simple, it is actually not as simple as everyone imagines. Volume B has the highest flexibility and the greatest uncertainty. Paper A is a little more difficult, but you are likely to be drawn into a major related to civil engineering, which will give you an advantage. After struggling with this and that, everyone realized that the biggest sin was that their abilities were too poor. After looking at the test paper, all three of them felt a little discouraged. When Lu Shan listened to the three people arguing about these topics, he knew that their level was too poor. Both the ABC volumes were very simple for Lu Shan. This may be some of the insights that come from mastering mathematics. He had finished reading the book in his hand and had no time to deal with these people. He closed the book and prepared to leave. It was only at this time that the three of them realized that Lu Shan was actually reading a book in the corner. Moreover, Lu Shan’s book also contains examples related to mathematical modeling. Lu Shan picked up the book casually. After all, Chen Liang had been urging him to participate in the Mathematical Modeling Competition, but he had always declined. Although I declined, I still wanted to take a look at what the Mathematical Modeling Competition was about, so I picked up a few books at random. It turned out that they were not difficult at all, and I lost interest in participating. Fan Bing recognized Lu Shan immediately. After all, Lu Shan is quite special in the class. First of all, he did not come to the military training, and the counselor did not blame him. Secondly, Lu Shan always sat in the back row during class, but every teacher recognized Lu Shan and liked to ask him questions. When his classmates were still thinking about how to solve a problem, Lu Shan had already given a complete answer. During the first week of school, some students majoring in applied mathematics had more or less heard about Lu Shan's legendary story. They knew that he was the top scorer in the college entrance examination in Jiangyang Province and was particularly good at mathematics. Fan Bing greeted Lu Shan enthusiastically, and said to Wen Feng excitedly, "Brother Feng, I will withdraw from the Mathematical Modeling Competition if you and Senior Sister Yu team up. Anyway, we can adjust the team members before the competition starts. Lu Shan is a classmate of ours, and he is very good at math. If you invite Lu Shan to participate, he will definitely win a prize!" Wenfeng looked at Lu Shan with some doubt. A freshman holding examples of mathematical modeling in his hands, does that prove that he is very good? Lu Shan humbly said that he didn't know the answer and was about to leave, but Fan Bing pulled him back and asked him to explain the question to him. (End of this chapter)
