* * America can communicate with lecturers * *. The full name of Meisai is Mathematical Modeling Competition (MCM/ICM), which is an influential competition in the field of mathematics. During the competition, participants usually need to complete modeling, data processing, model optimization and other work independently, but they can communicate with the instructor if necessary.

For example, if you encounter difficulties or bottlenecks in key links such as topic selection, modeling ideas and algorithm design, you can discuss with your tutor and seek advice and help. In addition, before submitting the paper, you can also ask the instructor to help you review it in order to better improve your work.

It should be noted that during the competition, try to complete the competition tasks independently and minimize the dependence on the instructor. If you encounter difficulties, you can make rational use of your tutor's resources and experience, but don't rely entirely on your tutor. You should learn the ability to think and solve problems independently.
