As far as I know, there are three participants in the mathematical modeling contest, at least one of whom can program, one has a good knowledge of language and writing, and the other is good at mathematics. Programming can use C language, as if the mainstream is also C language, of course, C++ will be better; Good Chinese is used to write papers. At least the model needs to be expressed to people. How to express it? We need such talents. If people who are good at math are active in thinking, they will basically have ideas when they get the questions, so the whole group may be relaxed. These three are indispensable, but it is best for three people to have these three conditions at the same time. Of course, we should work together, because the purpose of the mathematical modeling contest is to let students develop in an all-round way and have team spirit. In addition, MATLAB is a good modeling software, which is actually a language. I don't know if there is anything wrong, I hope better experts can point it out ~
