Hi guys
tristan is a new student here and he would like to work on collection
optimization and implementation.
I would like the get some ideas from you.
- are there some collections that would be cool to improve?
Here's the list I plan to improve is Squeak:
- OrderedCollection: fix the growing behavior, adding n elements takes
O(n^2) time in some cases
- SortedCollection: just deprecate it (or replace it's crappy
quicksort implementation if you really want to improve it. But I think
it's useless)
- TextStream: adding n characters with different attributes has O(n^2)
runtime
- StandardFileStream >> #upTo: (the recursive call + concatenation
requires O(n^2) runtime and O(n^2) memory for large chunks of data)
Levente
- are there some collections that would be cool to have and that we do
not have yet?
If you have any idea related to optimizations let me know.
