Re^2: Iterating through Two Arrays. Is there a better use of memory?
in thread Iterating through Two Arrays. Is there a better use of memory?
Back in the day, I made a traveling salesman problem solver which used Perl hashes to reduce the search space. The script started using gigabytes of memory once you got above a few million hash keys. If you're dealing with thousands of items, I wouldn't worry unless you're in a low-memory environment.
