It is an international mathematical modeling competition sponsored by the Mathematical Society of Inner Mongolia Autonomous Region and the Global Mathematical Modeling Ability Certification Center, and hosted by the Mathematical China website. It is a warm-up match before the United States, and it is called "Little Beauty Match". All the rules of the competition are similar to those of USA, but the cost is only RMB 65,438+000, which is very suitable for students who want to participate in the internship or school selection of USA.
