Some of them are papers from earlier years, which I saw in the process of learning mathematical modeling. There are the following points to pay attention to: 1, pay attention to the format, learn the format and typesetting of excellent papers, and find key award-winning points in combination with topics. The reason why a paper can win an award must be something that makes the judges and teachers shine, that is, something that ordinary people can't think of. Know these excellent places. 3. Read the full text in detail, read and understand every step of his deduction, feel the breakthrough point of the author's problem solving in that year, and learn the model. The other part is the papers in recent years. I advise you not to read these documents yet. Do it first and finish your paper from beginning to end. I may not be familiar with it at first, but I can take a longer time, but other things can't be changed (the number of people can't exceed three, and I don't look at the excellent papers on this topic when I look up the materials). Finish your thesis thoroughly. Then pay attention to the following points: 1, look at the model! What are the advantages and disadvantages of your model compared with excellent papers? If yours is better than his, it's over. But ask yourself why he used that model and you didn't. Is it because you know too little about the models? Or look at the problem from the wrong angle, I didn't expect it? Look for gaps and make up for deficiencies. 2, find yourself not! What points did he not think of, could not be solved at that time, and how did he solve them? Learn some ideas from others to solve problems. 3, look at the typesetting! On the whole, who is more comfortable than typesetting? Mathematical modeling competition, after all, is a mathematical competition. A good paper must have prominent formulas and a strong "mathematical flavor". The same question, why are there fewer formulas? Summarize it yourself. If time is limited and you can't finish the first part of the beginner, you can go directly to the second part.
