I am very happy that the team has assisted the national competition for 4 consecutive years. Our digital and analog related answers have helped hundreds of thousands of teams. I also got the support of 1w+ fans in Zhihu.
The following will give you some of the team's previous experience and how to prepare for the mathematical modeling competition:
This article is very suitable for viewing by modelers at all stages, full of dry goods! (Super detailed strategy, the full version is answered below):

2.2 Suggestions for participation (personal opinion)
The optimal order of participation should be:
1. Hands-on competition (choose one or more):
May Day modeling (the topic is simple, but registration fee is required)
Strongly promote the Electrician Cup (the topic is moderate, the gold content is OK, no registration fee is required)
Certification Cup (There are two stages, the gold content is not directly proportional to the difficulty of the topic, registration fee is required, students who have not participated in modeling are not recommended to participate)
2. Advanced game
Mathorcup (higher difficulty, last year's difficulty was the same as the national competition, registration fee is required, if you don't have time, you can not participate)
The American competition (although it is an advanced competition, but the time is 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. At present, most colleges and universities in China are acceptable. If the school does not reimburse the registration fee and has no guarantee for research or other similar reasons, you can not participate. It is not recommended to form teams across schools, because the certificate only has one school name)
3. National Undergraduate Mathematical Contest in Modeling
It is listed separately because most colleges and universities in China now recognize this competition, and the number of participants is very large and the gold content is very high.
3 How to prepare (full of dry goods, pure hand-to-hand, I hope everyone will support it)
3.1 Select teammates and task assignments (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 competition and can exercise your teamwork ability to a great extent. The joy when I came up with a good idea, the program ran successfully, and especially when I finally finished my thesis, is beyond words. I think this kind of experience is more important than the result of the competition.
The following are my suggestions for selecting teammates: (Article 8 has the highest priority)
1 Do not find the kind of people who have a lot of things (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, and some boys will not choose to let girls stay up late or girls have menstruation or girls find boyfriends because of pity. Come (especially dangerous, I saw someone was actually beaten in Zhihu before, because he made the girlfriend of the boy who beat him stay up late) this will undoubtedly greatly affect the game
2 Never find a couple! (cough cough, not much to say)
3 The best matching plan: three men or one woman and two men (optimal), one man, two women or three women are not recommended (especially for girls, I think I will regret it sooner or later if I give up an opportunity because of a good relationship)
4 Matching: modeling hand + thesis hand + programming hand (the most important of which is the thesis hand, because if the paper is well written, the algorithm may get good results if the algorithm is not good)
5 Professional suggestions for modeling hands: Mathematics/statistics/related majors are preferred
6 Major suggestion for thesis writers: This is possible regardless of the major, but liberal arts students choose carefully, because even if the thesis is well written, some people may not be able to understand the ideas of modeling or programming hands
7 Professional advice for programmers: Computer-related majors (learning big data, machine learning, data science, etc. are preferred, and those who know matlab or python are preferred). As a programmer, modeling is more about doing algorithm problems.
8 It is always right to know the boss and find the boss to form a team
3.2 Digital and analog algorithm reserves and common 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 just explain which algorithms need to be mastered in advance.
The following are the algorithms that I think are very important and need to be mastered (referring to knowing the principle, being able to use code to implement or having a code template that can be implemented): (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 forecasting algorithm (see 3.4)
11 Multiple Linear Regression
12 cellular automata
Avoid pits: so-called intelligent algorithms such as simulated annealing, ant colony algorithm, genetic algorithm (it looks tall, but use it with caution, the teacher doesn't like teams using these algorithms)
3.3 Methods of studying excellent papers (importance: 4 stars)
