* * * in the United States, there are six awards, namely grand prize, grand prize candidate award, first prize, second prize, successful participation award and unsuccessful entry award, which are abbreviated as O prize, F prize, M prize, H prize, S prize and U prize. 0.5% for the o- Grand Prize, 1% for the F- Grand Prize candidate nomination, 13% for the M- Class Prize, 30% for the H- Second Prize and 55% for the S- Successful Entry Award.

The beauty contest refers to the mathematical modeling contest for American college students, which is sponsored by the American Federation of Mathematics and Its Applications. It is the only international mathematical modeling contest and the most influential one in the world. The content of the competition involves many fields such as economy, management, environment, resources, ecology, medicine and safety.

The mathematical modeling competition for American college students is divided into MCM and ICM, which are conducted according to unified standards. After the competition topics came out, the parameter team selected topics through official website and the United States, which were divided into six categories.

MCM: There are high requirements for the contestants' mathematical model literacy and modeling ability. Generally, A is a continuous problem and B is a discrete problem. Question C is related to big data and data mining. ICM: Generally speaking, the problems involved are macroscopic and complicated.

Participants are required to grasp the main line of the problem and weigh the macro and micro, the whole and the details. ICM has three problems, D is generally related to network science or optimization, E is related to environmental science, and F is related to policy and social science, mainly discussing modeling in social science.

Precautions:

Generally speaking, the problem of the American championship is difficult. It is not easy for users to come up with a very excellent scheme in four days. Therefore, in the competition, we must first come up with a feasible plan as a security model to solve.

If there is enough time, further deepen the model, consider more factors to enter the model, and deepen the problem step by step.

In the real scientific research process, the result analysis is a very important and indispensable part, as well as in American competitions. Detailed result analysis can easily improve the grade of the paper, which is the key difference between the international first prize and the international second prize, and even can impact the special prize by virtue of this.
