40 Bat Algorithm (BA)
ego networks from [?] are combined into one big network. The resulting network is
an undirected network that contain 3959 nodes and 84243 edges. Despite that there is
no clear community structure for the network, a ground truth structure was suggested
in [?]. For the tested dataset, we applied the bat algorithm 10 restarts and calculated
the NMI and modularity value of the best solution selected. This process was repeated
10 times and average NMI and average modularity are reported. The bat algorithm was
applied with the following parameter values: number of BA in the population np = 100
and the maximum number of iterations M
