    Hybrid pattern-matching algorithms on indeterminate strings

  • Original language description

    In a string x on an alphabet, a position i is said to be indeterminate iff x[i] may be any one of a specified subset of alphabet. A string x containing indeterminate positions is therefore also said to be indeterminate (or generalized). Indeterminate strings can arise in DNA and amino acid sequences as well as in cryptological applications and the analysis of musical texts. In this paper we describe a family of fast algorithms for finding all occurrences of a pattern p = p[1..m] in a given text x, whereeither or both of p and x can be indeterminate. Our algorithms are based on a very fast exact pattern-matching algorithm recently proposed by Franek-Jennings-Smyth that combines both Boyer-Moore-Sunday and Knuth-Morris-Pratt approaches. On many of the indeterminate pattern-matching cases tested, the new algorithms execute significantly faster than well-known bit-mapping algorithms based on the Unix utility agrep, while at the same time going beyond standard agrep's functionality.

    Hybridní vyhledávací algoritmy pro neurčité řetězce

  • Czech description

    Pozice i v řetězci je neurčitá právě tehdy může-li x[i] obsahovat libovolnou podmnožinu vstupní abecedy. Řetězec obsahující tyto pozice se nazývá neurčitý. Neurčité řetězce se objevují DNA sekvencích stejně jako v kryptografických aplikacích a analýze hudebních textů. Naše algoritmy vycházejí z velmi rychlého algoritmu pro přesné vyhledávání nedávno představeného autory Franek-Jennings-Smyth, který kombinuje BMS a KMP přístupy.
