call it by its real name, "shuffling". Pure random shuffling designed to keep everyone guessing, bleeding and ad spending
I agree with the word "shuffling", but not with the design that you are assuming. I think the design is statistical sampling: rapid testing of user response to various ranking schemes. And yes, it changes so fast you can only guess at the logic behind it, but I think there IS logic rather than randomness.
