" AoCMM 2015 is my first math modeling contest-----it was really fun and intriguing!
The problems were really challenging, especially the second one, since the functioning GPS was something that my friend and I were totally unfamiliar with. And the hard part lies in the limited time, during which we needed to pore over background information, form our ideas, write the solution and computer programming....
Since we had only two people in the team, there indeed ain't enough time for us to track all these issues, so we decided to focus more on building the model and analyze the approach we use than programming and seeking numerical result (Another reason was because neither of us was proficient in programming).
Our models were built on our own interpretation of the problems, and we tried to make them as specific as possible. For example, we illustrated a test design depending on student profile (problem 1), and used matrices to represent the input (student profile) as well as the output (expected score). We also defined the ideal score distribution to be the normal distribution. In our solution to the second problem, we simplifies the problem by analyzing two time-independent GPS constellations. We also designed ways to test instant visibility and compute the expected visibility period of a location on earth in order to ensure the functioning of the system.
During the competition, Zhengzhi and I cracked the first problem together, and as I started to formulate down our ideas and write the solution paper, Zhengzhi set out for background information on GPS. This is just a way to save time and make efficiency. (Well, after the three-day competition, I think I would recommend coming with a team of three or four. This will make everyone more focused and less stressed.)
After all, it's truly a great experience with AoCMM. Look forward to attending next year!"
