Those are the ones I'm enjoying the most - usually I get a larger value as the parameter in the first or second run, and I can make some sort of connection between the parameter and the result to refine my function accordingly. (It's rather hard to get the right function out of 2->6, which was the first run for my first test, but once I got 789->310866 I was able to get the right answer after only two more tests).
