+Therefore, there is a small distance between the energy and
+the performance curves in a homogeneous cluster compare to heterogeneous one, for example see the figure(\ref{fig:r1}) and figure(\ref{fig:r2}) .  Then the
+algorithm starts to search for the optimal vector of the frequency scaling factors from the selected initial 
+frequencies until all node reach their minimum frequencies.
