Modeling is either to innovate your own model or to use existing mature models. Either way, you need a high level of basic knowledge. Even the existing model, if not used before, can only be used by looking up information on the Internet. Without basic knowledge, it is impossible to master it in just three days during the competition.

It is enough for linear algebra to master the basic operations of matrices. A member of C and MATLAB must be proficient, and so must lingo language.

In other aspects, it is too difficult to master probability theory and mathematical statistics, the differential and difference of high numbers, and the interpolation and fitting of calculation methods. I don't know if you have studied it, but you don't have to master it well.

The recent modeling problems seem to require higher professional knowledge. I don't know what you are studying, but you still have to master the basic physics of college.

I've thought so much for the time being
