本文深入探讨了每类算法中的代表算法，其中根据数据挖掘中枚举树相关技术提出了一种可能的公共子树查找算法的思想。

Among these three categories a possible common subtree algorithm is presented based on the enumeration tree technique of data mining domain.

zippers的枚举函数允许您按照深度优先的顺序遍历整个树，如图11所示。

A zipper's enumeration functions allow you to traverse the entire tree in depth-first order, as shown in Figure 11.
