- W4300872278 abstract "It is widely assumed that $O(m+lg sigma)$ is the best one can do for finding a pattern of length $m$ in a compacted trie storing strings over an alphabet of size $sigma$, if one insists on linear-size data structures and deterministic worst-case running times [Cole et al., ICALP'06]. In this article, we first show that a rather straightforward combination of well-known ideas yields $O(m+lglg sigma)$ deterministic worst-case searching time for static tries. Then we move on to dynamic tries, where we achieve a worst-case bound of $O(m+frac{lg^{2}lgsigma}{lglglgsigma})$ per query or update, which should again be compared to the previously known $O(m+lgsigma)$ deterministic worst-case bounds [Cole et al., ICALP'06], and to the alphabet emph{in}dependent $O(m+sqrt{lg n/lglg n})$ deterministic worst-case bounds [Andersson and Thorup, SODA'01], where $n$ is the number of nodes in the trie. The basis of our update procedure is a weighted variant of exponential search trees which, while simple, might be of independent interest. As one particular application, the above bounds (static and dynamic) apply to suffix trees. There, an update corresponds to pre- or appending a letter to the text, and an additional goal is to do the updates quicker than rematching entire suffixes. We show how to do this in $O(lglg n + frac{lg^{2}lgsigma}{lglglgsigma})$ time, which improves the previously known $O(lg n)$ bound [Amir et al., SPIRE'05]." @default.
