Robustness of Scale-free Networks - Science Collaboration
Suppose that the COVID-19 virus suffers a strange mutation, and now it is extremely mortal only to scientific researchers. Taking into consideration the Science Collaboration network, it will break apart into many isolated sub-graphs of researchers, after the death of how many scientists? Additional data about the network: Nodes ($N$): 23,133 $<k>$ (Average degree distribution of the network): 8.08 $<k^{2}>$ (Variance of the degree distribution): 178.2 Hint: Round the number of dead scientists up. A. 19,136 B. 22,035 C. 7,937 D. 15,498 E. None of the above. Original idea by: Felipe Crispim da Rocha Salvagnini
