提出了一种一般系统发育树的度量方法。这扩展了为二叉树构造的工作。提出的度量使得可能出现在文献中的许多非二元系统发育树的比较。这提供了一个程序，比较不同的方法构建系统发育树。该度量基于将一棵树转换为另一棵树的基本操作。给出了应用这些操作所获得的结果。它们可以有效地计算任何一对树之间的距离。这将以前的工作推广到内部顶点可以被标记的情况，并且标签可以包含多于1个元素或者可以是空的。
A metric on general phylogenetic trees is presented. This extends the work constructed for binary trees. The metric presented makes possible the comparison of the many nonbinary phylogenetic trees appearing in the literature. This provides a procedure for comparing the different methods for constructing phylogenetic trees. The metric is based on elementary operations which transform 1 tree into another. Results obtained in applying these operations are given. They enable the distance between any pair of trees to be calculated efficiently. This generalizes previous work to the case where interior vertices can be labeled, and labels may contain more than 1 element or may be empty.
