Critical Threshold in Correlated Networks

Generate three networks with $104$ nodes, that are assortative, disassortative and neutral and have a power$-$law degree distribution with degree exponent $=2\mathrm{.}2.$ Use the Xalvi$-$Brunet & Sokolov algorithm described in SECTION $7\mathrm{.}5$ to generate the networks. With the help of a computer, study the robustness of the three networks against random failures, and compare their P$($f$)/$P$(0)$ ratio. Which network is the most robust? Can you explain why?
