Yu Miao, captain of the first prize team in w88 casino’s 2010 National Mathematical Modeling Competition

Speaking of the origin of interest in mathematical modeling, Yu Miao said that it was originally because teachers would mention mathematical modeling from time to time in higher mathematics classes. Those professional terms ignited his curiosity, and he found it very interesting to apply mathematical knowledge to solve practical problems. So since he was a freshman, he began to pay attention to mathematical modeling.

The first time they saw the question "Displacement identification of oil storage tanks and tank capacity table calibration", they concluded that this question required a lot of mathematics knowledge and was difficult for them. In contrast, "2010Quantitative Assessment of the Impact of the Shanghai World Expo" is a relatively less restrictive topic. To weigh the two aspects, they chose "20109834_9978

Just started doing it"2010When looking at the topic "Quantitative Assessment of the Impact of the Shanghai World Expo", the three people first thought of the click-through rate of the World Expo website, the number of tourists, the search volume of vocabulary, and the development of Shanghai during the World Expo. However, these data were very scattered and difficult to sort and classify. So they chose a somewhat risky plan——The impact of the Shanghai World Expo on the stock market.

Although the competition lasted for three days, they actually had to complete the task within two days and use the remaining day to write the paper, so time was very tight. "During the competition, we worked outside for three consecutive days all night: setting topics, reviewing information, organizing data, building models, drawing planning tables, and calculating results……”On the last day, they returned to w88 casino for a series of paper corrections, abstract writing, and binding of the final results. short72The hour has become a critical moment to test the explosive power of each of them. All the knowledge reserves and all the sparks of inspiration are exploded at this moment.

Recalling every detail of the game, Yu Miao felt a lot.“Our teacher sacrificed his rest time to train us.” Yu Miao said movedly. "During the final game, the teacher even stayed up late with us." He said that two seniors also gave usHe is a great help, both in knowledge and inspiration. Without them, I would have gone through this tense and busy life alone72Every hour will be even more difficult.

One of the reasons why mathematical modeling attracts Miao is that it does not have a unified standard answer. As long as the contestants continue to follow their own ideas, they can justify themselves and find the optimal solution to the problem based on the assumptions they set. During the competition, Yu MiaoheWu Yuqiao and Zhou Jiying have always kept their own whims and whims. Through the three people working together and seeking the optimal solution through multiple channels, they finally won the game.

“Mathematical modeling is not as difficult as most people think, it is related toMathematics competitions are two completely different concepts. Yu Miao said with a smile. In his view, the modeling competition is more like a business case competition. This type of competition requires contestants to use their own thinking to answer questions and reach reasonable conclusions, rather than to solve a mathematical problem as we think. The characteristic of modeling is that contestants have to use mathematical language to explain the problem. The knowledge used in modeling can basically be learned in the second semester of junior year. Yu Miao reminded the contestants: "The final results of modeling are graded by professors from the mathematics department. What they want is quantitative analysis, not your rich professional knowledge. If the paper is made up of professional formulas and professional terms, then the paper has been sent to the wrong place."

At the end of the interview, Yu Miao concluded that both strength and inspiration are very important for participating in the competition. Mathematical modeling tests not only the tenacity and seriousness of the contestants, but also the flash of wisdom. Combining endurance and explosive power at the same time, whoever can become a strong player on the stage.
