Tries and patricia tries are two popular data structures for storing strings. Let Hn denote the height of the trie (the patricia trie, respectively) on a set of n strings. Under the uniform distribution model on the strings, it is well known that Hn/...

The Patricia trie is a simple modification of a regular trie. By eliminating unary branching nodes, the Patricia achieves better performance than regular tries. However, the question is: how much on the average is the Patricia better? This paper offers ...

We need to access objective information efficiently and arbitrary strings in the text at high speed. In several key retrieval strategies, we often use the binary trie for supporting fast access method in order. Especially, the Patricia trie (Pat tree) ...
