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

Random network

Which of the following statements regarding random networks is true? I. Real networks follow the same properties as random networks. II. The exact degree of distribution of a random network is calculated by the binomial distribution. The binomial distribution depends only on one parameter, <k>. III. An approximate way to calculate the degree of distribution of a random network is through the Poisson distribution. To make this approximation, the value of N must be large and the value of the probability p must be small. IV. The Poisson distribution depends only on one parameter <k>, while the Binomial distribution depends on p and N. A. All of the above B. II and III C. III and IV D. III E. None of the above Original idea by: Caroline Nakazato
