Network Robustness

Which statement about robust networks is incorrect? The  Molloy-Reed criterion , stating that a randomly wired network has a giant component if  κ < 2. κ = ⟨ k 2 ⟩ k > 2 During an attack we aim to inflict maximum damage on a network. We can do this by removing first the highest degree node, followed by the next highest degree, and so on. Scale-free networks are robust to random failures, but not robust to attacks. The power-law distribution followed by blackouts, information cascades and earthquakes indicates that most cascading failures are relatively small. None of the above Original idea by:  Caroline Nakazato
