It is not Huawei Cup Mathematical Modeling Competition, but an academic competition for graduate students to learn the application of mathematical modeling. The winners are all based on their real strength, and there is nothing inside. Huawei Cup Mathematical Modeling Competition takes the form of a team with no more than 3 people. The topics of the competition involve all disciplines such as literature, science, engineering and medicine. Choose one of the six big topics from A to F, and each big topic contains three or four small topics. Each problem has its own key direction, which can be roughly divided into prediction, evaluation, principle modeling and optimization.
