In computer science, Ukkonen's algorithm is a linear-time, online algorithm for constructing suffix trees, proposed by Esko Ukkonen in 1995. The algorithm begins with an implicit suffix tree containing the first character of the string. Then it steps through the string, adding successive characters until the tree is … See more While generating suffix tree using Ukkonen's algorithm, we will see implicit suffix tree in intermediate steps depending on characters in string S. In implicit suffix trees, there will be no edge with $ (or any other termination … See more Ukkonen's algorithm constructs an implicit suffix tree Ti for each prefix S[1...i] of S (S being the string of length n). It first builds T1 using 1 character, then T2 using 2 character, then T3 using 3 character, ..., Tn using the n character. You can find the following … See more • Detailed explanation in plain English • Fast String Searching With Suffix Trees Mark Nelson's tutorial. Has an implementation example written with C++.
