Mathematical modeling competition for college students is a competition that needs to comprehensively apply mathematics, computer science and engineering knowledge to solve practical problems. Participants need to have the following skills and knowledge reserves:

1. Mathematical foundation: Participants need to have a solid mathematical foundation, including advanced mathematics, linear algebra, probability theory and mathematical statistics. These basic knowledge are the basis for solving practical problems.

2. Programming ability: Participants need to master at least one programming language, such as MATLAB, Python or C++. Programming ability can help contestants realize model algorithm quickly and improve the efficiency of problem solving.

3. Data processing and analysis: Participants need to have certain data processing and analysis capabilities, and skillfully use Excel, SPSS and other tools for data sorting, analysis and visualization.

4. Professional knowledge: According to the characteristics of the competition, participants need to have certain professional knowledge, such as physics, chemistry, biology and economics. These professional knowledge can help participants better understand the background of the problem and improve the quality of problem solving.

5. Teamwork: Mathematical modeling competitions usually require three people to form a team. Participants need to have good teamwork skills, be able to communicate effectively with teammates and solve problems together.

6. Innovative thinking: Participants need to have certain innovative thinking ability and be able to put forward novel ideas and methods in the process of solving problems.

7. Time management: Mathematical modeling competitions usually have time limits. Participants need to have good time management skills, arrange time reasonably, and ensure that the competition tasks are completed within the specified time.

8. Thesis writing: Participants need to have certain paper writing ability, and can clearly and concisely express the problem-solving process and results.

In a word, the mathematical modeling competition for college students requires the contestants to have solid mathematical foundation, programming ability, data processing and analysis ability, professional knowledge, teamwork, innovative thinking, time management and paper writing skills and knowledge reserves. By participating in the mathematical modeling competition, participants can exercise their comprehensive quality and improve their ability to solve practical problems.
