Taking vol/cap ratio-dependent impedance into account leads volume fluctuations between the individual iteration steps. In order to obtain a valid result, the results of previous iterations are used in the new iteration. Smoothing the procedure affects the connection volumes calculated. It is carried out using exponential smoothing or the method of successive averages (MSA).
Method of Successive Averages (MSA)
According to this formula, the smoothed connection volume V in iteration i is derived from the volumes of previous iterations:
with smoothed connection volume v*, connection B in Iteration i and newly calculated volume v.
This means connection volumes obtained from the search are not included in the first iteration.
Exponential smoothing
According to this formula, the smoothed vol/cap ratios of connection V in iteration i is derived from both the calculated volume and the smoothed volume of the previous iteration:
Parameter a has to be defined by the user, the value range is 0..1.
