12.4.2 Formalization of Algorithm Granularity
The algorithm granularity requires continuous monitoring of the compu-
tational resources. This is done over fixed time intervals/frames, here denoted
as T F . According to this periodic resource monitoring, the mining algorithm
changes its parameters to cope with the current consumption patterns of re-
sources. These parameters are AIG, APG and AOG settings discussed briefly
in the previous section. It has to be noted that setting the value of T F is
critical for the success of the running technique. The higher the T F is, the
lower the adaptation overhead will b
