Damn ... must read more carefully ... I must have skipped way down or something...?? Thats what you get when you have an attention span of a kitten catching flies. BTW: I've found the article on finite state machines as tries - low memory overhead, in particular, the fsm can be updated incrementally and it is fast to do so: Incremental Construction of Minimal Acyclic Finite-State Automata http://acl.ldc.upenn.edu/J/J00/J00-1002.pdf How to squeeze a lexicon http://sun.iinf.polsl.gliwice.pl/~mciura/lexicon.pdf http://www.google.com/search?sourceid=navclient&hl=da&ie=UTF-8&oe=UTF-8&q=Da ciuk+minimal+tries (Robert Feldt posted a link here at c.l.r. a year back) http://lampwww.epfl.ch/papers/idealhashtrees.pdf
