American Competition refers to American Mathematical Modeling Competition (MCM/ICM), which is an international mathematical modeling competition. The competition is held in the United States every year and is jointly sponsored by the American Mathematical Association (MAA) and the American Institute of Industrial Applied Mathematics (SIAM). The specific venue of the competition will change according to the year and the arrangement of the organizer, and it will be held in an American university or conference center. The purpose of the competition is to encourage students to use mathematical modeling to solve practical problems and attract students from all over the world to participate.
