Figure 4
Theoretical prediction of the variance σ2 in comparison with the simulation results.
The system has size 
and power-law degree distribution 
with scaling exponent 
. The theoretical prediction does not depend on the value of the average degree. In direct simulations, the values of the average degree are 
, 10, 14 and 40. The simulation results denoted by symbols are the same as those plotted in Fig. 1, with the pinning pattern indicator to be 
.
