Some mathematical modeling forums download some modeling competition papers. In writing the thesis of mathematical modeling contest, it is suggested to take a look at the case analysis of mathematical modeling contest I think the case analysis compiled by Zhu Daoyuan is of reference significance, which is the essence of modeling. In addition, the case analysis compiled by Jiang Qiyuan and Xie Jinxing is also good. Recently, there is a book "Application of Matlab in Mathematical Modeling" published by Beihang Press. The second article in the book is a real national competition award-winning paper, with a detailed Matlab solution source program, which is also very good. I think these books are very helpful to participate in the mathematical modeling competition. The landlord may wish to have a look. Dangdang, Zhuo Yue, Taobao and major bookstores should all have them, and libraries may also have these very classic books.

Electronic files don't seem too serious to be cherished. I suggest you have some good reference books at hand, which are familiar at ordinary times and can be used conveniently during the competition, and you can refer to them at any time. It is also convenient to write references in the paper.
