Diff for "GeometricMean"

Differences between revisions 3 and 4

The geometric mean of P1,..,Pn is

where latex2($$Normalized(P_i) = \frac{P_i}{Pn}$$) where n is the referenced execution time. Obviously the geometic mean of the referenced machine is 1.

One of the nice features of Geometric means is that the following property holds:
