I just participated in this year's national mathematical modeling competition for college students. I can elaborate on the above points below.
First of all, the competition time is limited. This year's time is from 6: 00 pm on September/KOOC-0/0 to 9: 00 pm on September/KOOC-0/3/0: 00 pm, but in fact, we basically have to submit the paper before 8: 00 pm on September/KOOC-0/3, because the paper can be submitted repeatedly before 8: 00 pm. So the timing of modeling is very important.
Let's talk about online resources. There are many resources on the Internet. I prefer to go to HowNet to find papers, but if your school network doesn't support free access to HowNet, you have to pay for it yourself. Of course, there are some other websites, such as CSDN, World Wide Web and Baidu Academic. In addition to online resources, you can also prepare a modeling book for yourself, but you don't need a book in general competitions, and it will be faster to look it up online.
Finally, talk about communication in modeling. In principle, only your group members are allowed to discuss topics. During the competition, all the modeling groups in the school will turn on the forbidden mode. Of course, even if the forbidden mode is not turned on, you can't ask questions in the group. If you ask directly, you will be convicted of violating the rules. Some students may think that it is enough to poke a big boss in private instead of asking in groups. In fact, such behavior is very dangerous. It can't be said that everyone who asks the big boss is found to be in violation of the rules, but it is also very likely that someone will poke the modeling problem and be found to be in violation of the rules. There are many such examples around me, so we should abide by the rules well in the competition.
