It's not a matter of having many collections, but of repeatedly making copies in nested loops. For instance, in uniqueTriCombiDo: using allButFirst: followed by withIndexDo: can be replaced by to:do: However, I guess the biggest gain would be in avoiding to enumerate potential triangles over the whole point set, since that's combinatorial; for instance http://en.wikipedia.org/wiki/Fortune%27s_algorithm -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet
