I like just responding with "are you sure?" continuously. at some point you'll find it gets stuck in a local minima/maxima, and start oscillating. Then I backtrack and look at where it wound up before that. Then I take that solution and go to a fresh session.
Except they have no concept of what "right" is, whereas I do. Once it seems to gotten itself stuck in left field I go back a few iterations and see where it was.
