Knuth-Morris-Pratt

[Jean-Christophe Filliatre]

As a byproduct of the  last ICFP programming contest, I'm releasing an
implementation of Knuth-Morris-Pratt string searching algorithm that I
wrote years ago. You can find it here, in my ocaml bazar:

  http://www.lri.fr/~filliatr/software.en.html

Just in case it may be useful, as it finally happened to be for myself.

Hmm. My KMP implementation turned out to be a real bottleneck in my
ICFP code; I suspected I should have chosen Boyer-Moore (not knowing
anything about the constant factors of each, just stabbing in the
dark)... Maybe it was the average-case O(log n) "get" in my "rope"
implementation...

Boyer-Moore is more useful with a large alphabet. With only 4
characters, I don't think it would have helped you a lot for the contest
(I might be wrong).

Nice + Thanks.

BTW: Many sources at your site aren't carrying any license/copyright
notice (kmp at least doesn't). If I understand european copyright law
right that means it defaults to look only, don't use, don't
distribute. Was that really your intention?
