The full name of the Mathematical Modeling Competition is the National Mathematical Modeling Competition for College Students, which is sponsored by the Higher Education Department of the Ministry of Education and is open to college students all over the country. Founded in 1992, the competition is held once a year, and now it has become the largest basic subject competition in colleges and universities in China and the largest mathematical modeling competition in the world. The purpose of the competition is to improve college students' mathematical modeling ability, stimulate their interest in learning mathematics, cultivate teamwork spirit, and improve their independent research ability through practice. Mathematical modeling generally solves the problems of evaluation, operation optimization and prediction. It is suggested that multiple softwares be used alternately, and you can try SPSSAU.
