After trying many implementations of Suffix Tree and Suffix Array in Python, the fastest I managed to get was based on adamant Ukkonen version: https://codeforces.com/blog/entry/16780 Here is my Python version enhanced with memoization (I tested it with UVA 10679 — I Love Strings!!), ...
We report on an implementation of the compressed suffix tree very recently proposed by Sadakane (Theory of Computing Systems, in press). The compressed suffix tree occupies space proportional to the text size, i.e.O(nlog|Σ|) bits, and supports all typical suffix tree operations with at most...

A suffix tree for a string S of length n can be built in Θ(n) time, if the alphabet is constant or integer. Otherwise, the construction time depends on the implementation. The costs below are given under the assumption that the alphabet is constant. If it is not, the cost depends on...
摘要: Suffix tree is one of the most important data structures in string algorithms and biological sequence analysis. Unfortunately, when it comes to implementing those algorithms and applying them to real关键词: Algorithm engineering Burrows-Wheeler transform balanced parentheses biological sequence ...
Suffix Tree 在DFS后就是 Suffix Array。 可见,只是字符串后缀的两种等价的表达形式,即:数据结构不同。 但实际上,只需要记录以下绿色的部分index即可。 Simply an arraycontaining all the pointersto the text suffixes listed in lexicographical order.

And, finally the implementation. Code: #sT8Vd1 I tried to make the code as simple and clear as possible :) I do not know if I managed to do so and hope for your feedback and questions.suffix tree, suffix trie, ukkonen, strings +...
An important choice when making a suffix tree implementation is the parent-child relationships between nodes. The most common is usinglinked listscalledsibling lists. Each node has pointer to its first child, and to the next node in the child list it is a part of.Hash maps, sorted/unsorted...
