Yah- I got the impression they are running white or pink noise through a bunch of filters and looking to see if there is any spectrum remaining at the perfect balance condition that represents a successful bin-packing. The idea is they thus exploit the assumed linearity (and accuracy) of ideal circuits by claiming an independent calculation is happening at each frequency (and they trigger the calculations form the noise source). Not implementable.
