Generalized Suffix Tree in Perl

monkfan has asked for the wisdom of the Perl Monks concerning the following question:

Dear monks,
Does anybody knows if there exist any Perl implementation for generalized Suffix Tree?
What I can only find so far is Shlomo Yona`s module. Which is very limited and not a generalized one.

Update: Just discoverd there is a new module Tree::Suffix that binds to libstree library,
it takes care of generalized suffix tree.

Regards,
Edward

...Shlomo Yona`s module. Which is very limited... What functionality or generalisation are you particularly missing? Update: Except from trying to contact Shlomo and maybe Offer and ask if they are interested or even into that kind of further development, I don't see anything that could help you right now. It seems the module wasn't meant to do what you need. Update 2: Further searching CPAN for "Tree" and "Trie" finds a bunch of modules. Maybe there's a more suitable alternative for you there?

This functionality, which is the essence of generalized suffix tree: Given a set of multiple strings we would like to construct a single tree out of it. Where as Yona`s only create one tree for one string. For a more complete explanation on generalized suffix tree, please kindly refer to the link I gave in my OP. Regards, Edward	[reply]

The following might be helpful: Re: finding longest common substring It constructs a suffix tree in order to find the largest common substring of multiple strings.	[reply]

Or if you want to build your own routines, Rex A. Dwyer gives a gentle introduction on suffix trees in Chapter 12 (esp. pp. 177--193) of Genomic Perl using the word banana and not some DNA or RNA as one might fear.	[reply]
