Time Complexity of Knuth-Morris-Pratt String Matching Algorithm

This project centers on the evaluation for the time complexity of Knuth-Morris-Pratt(KMP) string matching algorithm. String matching problem is to locate a pattern string within a larger string. The best performance in terms of asymptotic time complexity is currently linear, given by the KMP algorithm. In this algorithm, firstly a prefix for the pattern string is computed and then based on this...

Geometric Point Pattern Matching in the Knuth-Morris-Pratt Way

Given finite sets P and T of points in the Euclidean space R, the point pattern matching problem studied in this paper is to find all translations f ∈ R such that P + f ⊆ T . A fast search algorithm with some variants is presented for point patterns P that have regular grid–like geometric shape. The algorithm is analogous to the Knuth–Morris–Pratt algorithm of string matching. The time requirem...

Reconstructing the Knuth-Morris-Pratt algorithm

In my view, the Knuth-Morris-Pratt string searching algorithm is one of those “magic” algorithms that do something wonderful but are difficult to explain or understand in detail without a significant time investment. The pedagogical question that I would like to address is not just: “how does it work?”, or “why does it work?”, or “does it work?”. More importantly, it is: “how did they come up w...

On Compile Time Knuth-Morris-Pratt Precomputation

Many keyword pattern matching algorithms use precomputation subroutines to produce lookup tables, which in turn are used to improve performance during the search phase. If the keywords to be matched are known at compile time, the precomputation subroutines can be implemented to be evaluated at compile time versus at run time. This will provide a performance boost to run time operations. We have...
