Question 3 (Scale-free Networks)

Using the continuum formalism, a scale-free network has \[ p(k)=Ck^{-\gamma}, \qquad k \geq 1, \] with \(\gamma = 2.5\). Which expression gives the second moment \(\langle k^2 \rangle\) for a finite network with cutoff \(k_{\max}\)? \(\langle k^2 \rangle = \int_1^{k_{\max}} k^{-0.5}\,dk\) \(\langle k^2 \rangle = C\int_1^{k_{\max}} k^{-0.5}\,dk\) \(\langle k^2 \rangle = C\int_1^{k_{\max}} k^{-2.5}\,dk\) \(\langle k^2 \rangle = \int_1^{k_{\max}} k^{2.5}\,dk\) None of the above Original idea by: Antonio De Cesare Del Nero

Question 2 (Random Networks)

In a random network with \(N \gg 1\) and average degree \(\langle k \rangle = 3\), what is the expected fraction of nodes with degree 0 or 1 ? \(2e^{-3}\) \(3e^{-3}\) \(4e^{-3}\) \(1 - e^{-3}\) None of the above Original idea by: Antonio De Cesare Del Nero

Question 1 (Graph Theory)

In an undirected network, suppose there are exactly 4 triangles and exactly 6 additional connected triplets . According to the definition of the global clustering coefficient, what is the value of \(C_\Delta\)? \(\frac{1}{2}\) \(\frac{2}{3}\) \(\frac{3}{4}\) \(\frac{6}{7}\) None of the above Original idea by: Antonio De Cesare Del Nero
