  2. Re-Pair - Wikipedia

    en.wikipedia.org/wiki/Re-Pair

    Once the grammar has been built for a given input string, in order to achieve effective compression, this grammar has to be encoded efficiently. One of the simplest methods for encoding the grammar is the implicit encoding, which consists on invoking function encodeCFG(X), described below, sequentially on all the axiom's symbols. Intuitively ...

  3. LCP array - Wikipedia

    en.wikipedia.org/wiki/LCP_array

    In order to find the number of occurrences of a given string (length ) in a text (length ), [3] We use binary search against the suffix array of T {\displaystyle T} to find the starting and end position of all occurrences of P {\displaystyle P} .

  4. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

  5. Generalized suffix array - Wikipedia

    en.wikipedia.org/wiki/Generalized_suffix_array

    Generalized suffix arrays can be used to solve the pattern matching problem: [5]. Given a pattern and a text , find all occurrences of in .; Using the generalized suffix array of , then first, the suffixes that have as a prefix need to be found.

  6. Knuth–Morris–Pratt algorithm - Wikipedia

    en.wikipedia.org/wiki/Knuth–Morris–Pratt...

    In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.

  8. Substring - Wikipedia

    en.wikipedia.org/wiki/Substring

    The occurrences of a given pattern in a given string can be found with a string searching algorithm. Finding the longest string which is equal to a substring of two or more strings is known as the longest common substring problem. In the mathematical literature, substrings are also called subwords (in America) or factors (in Europe).

  9. String-searching algorithm - Wikipedia

    en.wikipedia.org/wiki/String-searching_algorithm

    A string-searching algorithm, sometimes called string-matching algorithm, is an algorithm that searches a body of text for portions that match by pattern. A basic example of string searching is when the pattern and the searched text are arrays of elements of an alphabet ( finite set ) Σ.
