First of all, I want to tell you that there is no competition for the electric cup this year (the electric cup is held every two years, and the time is 165438+ 10); The Higher Education Club Cup is held every September. Although it is called "national competition", its level, difficulty and influence are far greater than that of "electrician cup". (The Higher Education Club Cup is sponsored by the Ministry of Education and the Mathematics Industry Association, and all famous schools participate); (The Electrician Cup is sponsored by Northeast Li Dian University and Electrician Association, but generally famous schools do not participate (Tsinghua, Peking University, Zhejiang University, Beiyou ...));

As for how to prepare, 1. Read more excellent papers over the years to understand the framework and analysis ideas of the papers;

2. Read more reference books (such as MATLAB, eviews, spss ...)

3.MATLAB (mainly programming basics, grammar, drawing, it is best to make up some algorithms: genetic algorithm, graph theory ...)

4. Statistics, probability theory and linear algebra are actually unnecessary; Statistics and probability, mainly to understand the analysis tools such as spss.

5. Learn to search for information online (keep a few digital and analog websites: the website of Math China must be).
