他们都属于 Radix 搜索 (见Algorithms in Java (3rd Edition) Parts 1-4 : Fundamentals, Data Structures, Sorting, Searching第15章),

在论文Extendible hashing—a fast access method for dynamic files中提到的Radix search trees就是指Radix搜索,好像在教材中没有专门的Radix search trees这样一节,但只要搞清楚了Trie,Digital search tree之类的,再看Radix search trees的思想就没有问题了,因为他们到来自Fredkin在1960年发表的标题为“Trie memory”的文章。

Radix Sorts: Sorting methods that take advantage of the digital properties of the numbers are called Radix Sorting (ref Algorithms in C By Robert Sedgewick )
