Does the Machine remember already reported numbers?
If the machine from Person of Interest remembers absolutely nothing over midnight, shouldn't it repeatedly report the same (both relevant and irrelevant) social security numbers every day (to Finch and Control) until that person is killed or rescued? If it doesn't remember the numbers, it should discover (and report) the same number each day as long as that person fits the search criteria.
Maybe it remembers reported numbers so it doesn't report them again. Why are no reported numbers ever repeated on following days in the show?
Here's how I see it: Each day, the machine calculates probabilities based on various inputs. We aren't privy to what those inputs are. But presumably, one input is "Finch and the team are working on this person," or something to that extent. It doesn't need to remember that because Finch is constantly searching for stuff on his computer and has pictures taped up to his cork board, etc. So I figure an input of "Finch knows about this," probably lowers its urgency, and the machine picks the next highest person on the list.
