Okay, let's get down to business. The process of this model contest was terrible, but I gained some valuable experience from it.
Let me first talk about what kind of state I took part in the competition: I made some preparations during the holiday, but I haven't made any serious preparations since the beginning of school. I study the internet, and the study of specialized courses consumes my energy, and some of them are too busy. Then there was the day of the game, which was a bit hasty. Our group A and B, I, A came back from other places because of the epidemic and needed isolation, so we had to contact through the network, and B and I worked together to solve the problem.
After the topic was handed out, we began to choose the topic. After reading through the topics, we began to make a decision and chose one of them in the form of 2: 1 It's a little hasty to think about it now. Three people can spend an hour reading each question carefully and writing down the general idea of the topic, so that they can have a deeper grasp of the topic and choose a more suitable topic, and the three ideas will not fall into the dilemma of being unable to move after a broken idea. For example, this time: I put forward my general idea, and then I followed it, but there was a problem in the later analysis: I put forward my idea, and then three people followed my idea. My major limited my in-depth understanding of mathematics and statistics, and problems appeared when I needed specific analysis later.
Secondly, it is the time to do the problem. Examining questions is a very important process. When choosing a topic, we have a general grasp of the topic, but it is far from enough. At the end of our first day, I went back to the dormitory and read the topic twice, and found several details. Therefore, speaking like a book is extremely necessary for the examination of questions.
Next, you can answer. But when answering, there will also be some places to pay attention to. The first is when to start writing papers. Some teams may choose to write a paper after the problem analysis is complete, but in my opinion, the restatement and analysis of the problem in the paper is conducive to finding some details in the topic and clearing the way of thinking. As I mentioned at the beginning, writing helps to sort out ideas, so it is best for three people to write a paper, at least to restate and analyze the problem.
Modeling is a team matter and requires the cooperation of many people. Our group has a clear division of labor: A is responsible for writing papers because of online interaction, B and I are responsible for programming and data processing, and A and B are responsible for further analysis. This has the advantage of high processing efficiency, and it can also give full play to everyone's strengths, but it also has some shortcomings: it requires higher personal abilities, including communication skills.
Our group has carried out the division of labor, but due to inconvenient communication and insufficient personal ability, it has brought negative effects: after the data processing, A and B can't give me a clear algorithm to continue writing programs, but I have been processing the data, and the algorithm analysis of the problem is not so in-depth, and I am in trouble for a while.
The paper will be submitted when it is finished, so be sure to pay attention to the requirements when uploading it. By the way, the anti-cheating mechanism of mathematical modeling platform: MD5 code is an encryption algorithm. The first submission will encrypt the file information (such as the last modification time), generate the MD5 code and upload it. When submitting for the second time, the MD5 code of the file information will be calculated and compared with the MD5 code uploaded for the first time. If the file information changes, the MD5 code will be different. It is believed that the file has been modified, resulting in upload failure. So don't make any changes to the file after submitting the MD5 code, including copying and moving (although it has been tested that copying or moving the file will not modify the last modification time of the file). Of course, you can modify the document after the last submission.
The process of modeling is very difficult, but it can be experienced when it is more precious. This modeling is over, and I shouldn't have another one, but this experience will be my precious experience, so that I can meet the test in the future.
