Summary and Difficulty Analysis of Mathematical Modeling Competition Topics in the First Half of 2023

Summary and Difficulty Analysis of Mathematical Modeling Competition Topics in the First Half of 2023

​Because in recent years, the ABC questions of the national competition have been fluctuating, and there is not much qualitativeness. The current overall proposition direction is to change from the previous single model problem to data analysis + evaluation + optimization or prediction questions are B and C questions main proposition direction. In order to better grasp the main direction of this year's proposition, here is a compilation of the competition questions, problem-solving ideas, some competition papers, and the difficulty of all digital modeling competitions after the 2023 US competition. In order to better help everyone to help this year's national competition.

The difficulty of the competition is scored by four digital model teachers who have participated in the review of the competition area in the Shandong competition area, as well as four modelers from the US M team and the national team. The entropy weight method is used to calculate the weight of the scoring results. Combined score. Since many teachers are biased towards optimization, some rare optimization problems may not be scored high, I hope you understand​.

The results obtained by the entropy weight method are displayed at the end of the article.

The following is the final result
