构造模型解决数学问题的目的是利用转化与化归的思想,以简驭繁、化难为易、化特殊为一般,使问题的解决更加简洁、合理、快捷、易懂,给人以春风化雨般之爽快感觉.文[1]通过对“田忌赛马”这个大家熟悉的问题进行推广、研究,构造了一个数学模型,并举例说明了这个模型的广泛应用,同时指出了 The purpose of constructing a model to solve mathematics problems is to use the idea of ​​transformation and transformation, to simplify, simplify, and generalize, to make the solution to problems more concise, reasonable, fast, and easy to understand. The refreshing feeling. The article [1] promoted and studied the familiar problem of “Tianji horse racing”, constructed a mathematical model, and illustrated the wide application of this model, and pointed out that
