Subject: Sets and maps over integers implemented as Patricia trees
Date: Fri, 12 May 2000 10:46:06 -0700 (PDT) [thread overview]

Hello ocamlers,
I recently implemented sets and maps over integers as Patricia trees,
following a paper by Chris Okasaki.
(http://www.cs.columbia.edu/~cdo/papers.html#ml98maps)
These are much more efficient than the standard library AVLs regarding
accesses and merges. (Only a sequential insertion of elements is
slower, actually.)
The code is available here, under LGPL:

Je mets à disposition une implantation efficace d'ensembles et de
dictionnaires sur le type int, réalisée à partir d'arbres de Patricia,
selon un papier de Chris Okasaki.
