[Numpy-discussion] Implementing a "find first" style function
Thu Mar 28 06:04:15 CDT 2013
I've specifically not tuned it, primarily because the get the best tuning
you need to know the likelihood of finding a match. One option would be to
allow users to specify a "probability" parameter which would chunk the
array into size*probability chunks - an additional parameter could then be
exposed to limit the maximum chunk size to give the user control of the
maximum memory overhead that the routine could use.
I'll submit a PR and we can discuss inline.
Thanks for the response Nathaniel.
