  2. Longest repeated substring problem - Wikipedia

    en.wikipedia.org/wiki/Longest_repeated_substring...

    The string spelled by the edges from the root to such a node is a longest repeated substring. The problem of finding the longest substring with at least k {\displaystyle k} occurrences can be solved by first preprocessing the tree to count the number of leaf descendants for each internal node, and then finding the deepest node with at least k ...

  3. Longest common substring - Wikipedia

    en.wikipedia.org/wiki/Longest_common_substring

    The longest common substrings of a set of strings can be found by building a generalized suffix tree for the strings, and then finding the deepest internal nodes which have leaf nodes from all the strings in the subtree below it. The figure on the right is the suffix tree for the strings "ABAB", "BABA" and "ABBA", padded with unique string ...

  5. Closest string - Wikipedia

    en.wikipedia.org/wiki/Closest_string

    More formally, given n strings s 1, s 2, ..., s n of length m, the closest string problem seeks a new string s of length m such that d(s,s i) ≤ k for all i, where d is the Hamming distance, and where k is as small as possible. [2]

  6. String interning - Wikipedia

    en.wikipedia.org/wiki/String_interning

    With interned strings, a simple object identity test suffices after the original intern operation; this is typically implemented as a pointer equality test, normally just a single machine instruction with no memory reference at all. String interning also reduces memory usage if there are many instances of the same string value; for instance, it ...

  8. String (computer science) - Wikipedia

    en.wikipedia.org/wiki/String_(computer_science)

    The set of all strings over Σ of length n is denoted Σ n. For example, if Σ = {0, 1}, then Σ 2 = {00, 01, 10, 11}. We have Σ 0 = {ε} for every alphabet Σ. The set of all strings over Σ of any length is the Kleene closure of Σ and is denoted Σ *. In terms of Σ n,

  9. String-to-string correction problem - Wikipedia

    en.wikipedia.org/wiki/String-to-string...

    A single edit operation may be changing a single symbol of the string into another (cost W C), deleting a symbol (cost W D), or inserting a new symbol (cost W I). [2] If all edit operations have the same unit costs (W C = W D = W I = 1) the problem is the same as computing the Levenshtein distance of two strings.
