I am very happy that our team has assisted in the national competition for four consecutive years. Our numerical and analog-related answers have helped hundreds of thousands of teams. Many of our students have won the first prize in the national competition and the US competition. We It also received support from 10,000+ fans on Zhihu.
The following will give you some of the team’s national first-level contestants’ previous competition experiences and how to prepare for the mathematical modeling competition:
This article is very suitable for modelers at all stages to read, and it is full of useful information! (Super detailed guide, complete version is answered below):

2.2 Suggestions for participating (personal opinion)
The optimal order of participation should be:
1. Practice competition (select one or more):
May Day Modeling (the questions are simple, but a registration fee is required)
Strongly recommend the Electrician Cup (the questions are moderate, the gold content is acceptable, and no registration fee is required)
Certification Cup (there are two stages, the gold content is not directly proportional to the difficulty of the questions, a registration fee is required, and students who have never participated in modeling are not recommended to participate)
2.Advanced competition
Mathorcup (higher difficulty, the difficulty was the same as the national competition last year, registration fee is required, if you don’t have time, you don’t need to participate)
The US competition (although it is an advanced competition, it takes place after the national competition, so you can participate after the national competition. It is more difficult, requires English writing, and takes one day longer than the national competition. It is currently recognized by most domestic colleges and universities. If the school does not reimburse the registration fee and there is no postgraduate guarantee or other similar reasons, you do not need to participate. Cross-school teams are not recommended because the certificate only has one school name)
3. National Undergraduate Mathematical Modeling Competition
Listed separately because most universities in China now recognize this competition, with a large number of participants and high value.
3 How to prepare (full of useful information, purely hand-made, I hope you can support me more)
3.1 Selecting teammates and assigning tasks (Importance: 5 stars)
The most important thing is to choose a suitable teammate. If you have two good teammates, you will definitely fall in love with the modeling event and can greatly exercise your teamwork skills. The joy I feel when I come up with a good idea, when the program runs successfully, especially when I finally complete my thesis, is beyond words. I think this experience is more important than the result of the competition.
The following are my suggestions for selecting teammates: (Item 8 has the highest priority)
1. Don’t find someone who has a lot of things to do (regardless of men and women, in my experience, the proportion of girls is greater than that of boys). Many girls are unwilling to stay up late. Some boys will not choose to let girls stay up late because they cherish their beauty, or they will have their period, or they will find a boyfriend. (It’s especially dangerous. I saw on Zhihu before that someone was actually beaten because he asked the girlfriend of the boy who beat him to stay up late.) This will undoubtedly affect the game to a great extent.
2 Don’t look for a couple! (Ahem, I won’t go into details about the reason)
3 Best matching plan: three men or one woman and two men (optimal). One man, two women or three women are not recommended (especially girls, if they give up an opportunity because of a good relationship, I think they will regret it sooner or later)
4 Combination: modeling skills + essay skills + programming skills (the most important of which is thesis skills, because if the paper is well written, it is possible to get good results even if the algorithm is not good)
5 Professional recommendations for modelers: Mathematics/statistics/related majors are preferred
6 Professional suggestions for thesis writers: This is applicable to any major, but liberal arts students should choose carefully, because even if the thesis is well written, some people may not be able to understand the ideas of modelers or programmers.
7 Professional suggestions for programmers: Computer-related majors (those who study big data, machine learning, data science, etc. are preferred, and those who know matlab or python are preferred). Sometimes you need to be careful: people who are not necessarily good at acm will definitely be suitable. As a programmer, modeling is more about doing algorithm problems than doing it.
8 It’s always right to know a big guy and find a big guy to form a team with.
3.2 Digital and analog algorithm reserves and commonly used algorithm recommendations (importance: 3 stars)
There are a lot of searches on the Internet, so I won’t go into details one by one. Here I will just explain which algorithms need to be mastered in advance.
The following are algorithms that I think are very important and need to be mastered (referring to knowing the principles, being able to implement them with code or having code templates that can be implemented): (ranked in no particular order)
1 Fitting interpolation method
2 Time series algorithm
3 Simple graph theory algorithm
4 Linear programming, integer programming, multivariate programming, quadratic programming (can be realized with lingo and matlab)
5 Queuing theory
6 AHP
7 Gray comprehensive evaluation, gray prediction
8 A clustering algorithm (see 3.4)
9 A classification algorithm (see 3.4)
10 A prediction algorithm (see 3.4)
11 Multiple Linear Regression
12 Cellular Automata
Avoid pitfalls: so-called intelligent algorithms such as simulated annealing, ant colony algorithm, and genetic algorithm (it looks fancy, but use it with caution, the teacher doesn’t like teams that use these algorithms)
3.3 Methods for studying excellent papers (Importance: 4 stars)
