人类在长期解决问题的实践中发现了许多复杂问题,常可应用分类方法转化为若干个问题予以各个击破,这一方法后来被称为逻辑划分方法.这是因为分类应符合逻辑,不允许重复也不可以遗漏.这是取得成功的不可忽视的规则.为了便于理解,还是从有趣的实例说起. In the long-term practice of solving problems, mankind has found many complex problems. It can often be broken down by applying classification methods to several problems. This method was later called the logical division method. This is because the classification should be logical and not allowed to repeat Nothing can be omitted. This is a non-negligible rule for success. For ease of understanding, or from an interesting example.
