If you are an undergraduate science student, you can choose one of the two questions A and B, and junior college students can choose one of the questions C and D; Liberal arts students can choose one of A, B, C and D. You only need to finish one of them and write your paper well.

In fact, the important thing in the mathematical modeling competition is whether the model in your paper conforms to the reality and whether the result conforms to the actual problem; Then there is the language expression ability of your thesis! The same model and results, different teams have different expressions and different award-winning levels. So I hope you can grasp the following and hope to help you!
