One of the goals of the heuristic here (whether it was correctly
implemented or not) was to include hysteresis, that is, to avoid
moving for tiny improvements. As I read it, your new heuristic here
doesn't do that, so it will move for an improvement from 1.001 to
0.99999. Could you add some hysteresis?
