Well, we didn't make it clear in one or two sentences, and you won't know much about it. I participated in this year's mathematical modeling for college students. Anyway, what I want to do is based on mastering some commonly used mathematical software, such as matlab excel. I like to use spss myself. That software is basically used during the competition, mainly because it is convenient to process data. There are also learning tutorials available online. If English is not too difficult, please take the reading chinese version of the tutorial. Modeling is also divided into several modules. For example, solving problems with differential equations also requires some basic probability statistics of economics, especially statistics, which are still very useful. I only trained for a few days in summer. This is neither difficult nor simple. You can borrow model books from the library. It is very detailed. I really don't know what to say. Come on, then join the competition.
