Distributions of node degrees (a), path lengths (b), local clustering coefficients (c) and component sizes (d) for the real and the 25 optimal simulated networks in ‘Pharmaceuticals’(SIC code 283). The blue circles in our plots correspond to the mean values and the error bars correspond to the standard deviations of all the quantities we analyze on the 25 realizations of each optimal simulated collaboration network. In many cases, the error bars are not visible, because the values are very narrowly distributed across these 25 realizations.
