Complexity of Sequential Pattern Matching Algorithms

  title={Complexity of Sequential Pattern Matching Algorithms},
  author={Mireille R{\'e}gnier and Wojciech Szpankowski},
We formally define a class of sequential pattern matching algorithms that includes all variations of Morris-Pratt algorithm. For last twenty years it was known that complexity of such algorithms are bounded by a linear function of the text string length. Recenlly, substantial progress has been made in identifying lower bounds. However, it was not known whether really there exists asymptotically a linearity constant. We prove this fact rigorously for the worst case and the average case using… CONTINUE READING
