Subject: [Caml-list] Substring search on an array of strings
Date: Thu, 24 Jun 2004 09:52:37 +0200 (DST) [thread overview]
Message-ID: <Pine.A41.4.44.0406240832570.503890-100000@ibm1> (raw)
Bonjour,
Caml Str library does not seem to provide a function allowing to match
efficently a string in a array of strings.
I was wondering if there were already known algorithms for this before
I try the workarounds I had in mind :
i) building a 'superstring' with the array of strings (the shortest
superstring problem is NP but there are simple primal-dual
approximation algorithms) and use a classical search algorithm.
ii) try to lift the suffix Knuth-Morris-Prat automaton to work on the
union of the words instead of a single word (is this possible ?)
