In fact, people have been trying to find ways to curb cheating in mathematical modeling competitions. Although all kinds of cheating can never be completely eliminated, the fairness of mathematical modeling competition can be maintained as much as possible. Bottom line: resist cheating and always be on the road.
Broadly speaking, there are four kinds of cheating in mathematical modeling: one is hugging thighs; Second, seek guidance from people outside the team; Third, plagiarism; Fourth, the paper is written, not made.
First of all, say the first one, hold your thighs. In fact, strictly speaking, this situation is not cheating, but holding thighs can make some low-level people get short-term benefits, which is easy to produce unfairness. Although it is not illegal, the existence of soy sauce players is also a kind of destruction to the team itself. Precautions: Team up with people at your level.
Then the second kind, communication with people outside the team during the competition, is the most common phenomenon in mathematical modeling competition. According to the regulations, the instructor can't guide the team during the competition. However, most schools do not abide by this rule, and instructors often participate in it. Although the degree of participation is different, it affects fairness more or less and must be resisted.
In fact, in most high-level colleges and universities, the guidance of tutors to students is almost zero, and ultimately it depends on their own level. In some relatively low-level schools, basically a teacher guides a team, and sometimes the teacher even does more than the students.
Followed by the third kind, plagiarism has a long history and is also one of the most primitive cheating phenomena. However, in recent years, the National Games has successfully used the duplicate checking technology to shut out such papers.
Finally, fourth, ghostwriting is a very serious academic misconduct. Because I have been involved in the mathematical model circle for a long time, I really dare not compliment those who do it for me. Many of them did it on their behalf without winning any prizes. Some people are completely cheating money and won't write your paper seriously at all. Therefore, it is king to test your own level and win prizes.
No matter whether it is the national competition or the American competition, you should submit a signed guarantee when submitting your paper to ensure that you will abide by the rules of the competition. Although this guarantee is weak, it is also morally binding. In recent years, the national competition has done a very good job in preventing cheating, and the duplicate checking of papers has prevented excessive extraction and mutual plagiarism of documents; Thesis defense can restrain the writing of the thesis to a certain extent; Submitting the source code of the paper can prevent the results of the paper from being tampered with.
Although there are still some loopholes to be drilled, it is still relatively standardized in general. Comparatively speaking, the United States is relatively free and open. Although it explicitly opposes cheating, it is estimated that it is due to cost considerations and there are no substantive measures.
Finally, I want to talk about two competitions, one is the mathematical modeling competition for students in Dengfeng Cup (final), and the other is the data analysis competition for students in SAS China (preliminary and final). Both competitions were held in a fixed computer room, with invigilators, and the SAS competition was disconnected, which showed the true level of students.
For the mathematical modeling competition, it must have lost its original essence to completely confine students to the computer room. But I think it can also be made into a two-wheel system. In the preliminary competition, the final team is still selected by means of communication competition. The final is a closed game, and everyone can play again fairly. This can greatly improve the gold content of mathematical modeling awards and reduce contingency.
