def captureChange[T](x: T, initially: Boolean = true): Boolean

returns
true only when a discontinuity (i.e., a change) is observed on x (you may choose how to handle the first observation)

def flexGradient(epsilon: Double = 0.5, delta: Double = 1.0, communicationRadius: Double = 1.0)(source: Boolean, metric: (StdLib_Gradients.this)#Metric = nbrRange): Double

Idea: a device should change its estimate only for significant errors.
Idea: a device should change its estimate only for significant errors. Useful when devices far from the source need only coarse estimates. Flex gradient provides tunable trade-off between precision and communication cost.
epsilon
Parameter expressing tolerance wrt changes
delta
Distortion into the distance measure, such that neighbor distance is never considered to be less than delta * communicationRadius.
source
Source fields of devices from which the gradient is calculated
