Web1 jan. 2013 · Weiner, McCreight and Ukkonen all augment the suffix tree T with shortcuts called suffix links that are used to efficiently traverse the suffix tree. For a suffix tree node v = v 1 ⋯ v k, the M-link M (v) = u, McCreight suffix link (also used by Ukkonen), is defined to be a pointer to the suffix tree node u = v 2 ⋯ v k that is obtained by chopping off the … Web1 nov. 1997 · The terminology of the most recent algorithm, Ukkonen's on-line construction, is used to explain its historic predecessors, revealing relationships much closer than one would expect, since the three algorithms are based on rather different intuitive ideas. Abstract. We review the linear-time suffix tree constructions by Weiner, McCreight, and …

Faster suffix tree construction with missing suffix links

In computer science, a suffix tree (also called PAT tree or, in an earlier form, position tree) is a compressed trie containing all the suffixes of the given text as their keys and positions in the text as their values. Suffix trees allow particularly fast implementations of many important string operations. The … Meer weergeven The concept was first introduced by Weiner (1973). Rather than the suffix $${\displaystyle S[i..n]}$$, Weiner stored in his trie the prefix identifier for each position, that is, the shortest string starting at Meer weergeven The suffix tree for the string $${\displaystyle S}$$ of length $${\displaystyle n}$$ is defined as a tree such that: • The tree has exactly n leaves numbered from $${\displaystyle 1}$$ to $${\displaystyle n}$$ Meer weergeven If each node and edge can be represented in $${\displaystyle \Theta (1)}$$ space, the entire tree can be represented in An … Meer weergeven Various parallel algorithms to speed up suffix tree construction have been proposed. Recently, a practical parallel algorithm for … Meer weergeven A suffix tree for a string $${\displaystyle S}$$ of length $${\displaystyle n}$$ can be built in $${\displaystyle \Theta (n)}$$ time, if the letters … Meer weergeven Suffix trees can be used to solve a large number of string problems that occur in text-editing, free-text search, computational biology and other application areas. Primary applications include: • String search, in O(m) complexity, where m is the … Meer weergeven Though linear, the memory usage of a suffix tree is significantly higher than the actual size of the sequence collection. For a large text, construction may require external memory approaches. There are theoretical results for constructing … Meer weergeven WebAlbert R. Meyer. Edward Meyers McCreight is an American computer scientist. He received his Ph.D in computer science from Carnegie Mellon University in 1969, advised by Albert R. Meyer. [1] He co-invented the B-tree with Rudolf Bayer while at Boeing, [2] and improved Weiner's algorithm to compute the suffix tree of a string. [3] how to change to dvorak keyboard
