Benchmarks with variable node robustness.

<p>a A snapshot of the benchmark with hierarchical community structure and variable node robustness at . The behavior of the nodes as a function of and is described in the table, with the average in‐out ratio at the microcommunity resolution, and is the in‐out ratio at the macrocommunity resolution. In the table, down arrows, up arrows, and dashes denote increasing, decreasing, and constant values respectively of the quantities on average. b and e show the in‐degrees at each resolution, for microcommunities and for macrocommunities. Likewise, c and f show the ratio of in‐ and out‐degrees at each resolution, and . d shows the degrees of robustness at the micro‐scale and g shows the robustness on the macro‐scale. The behavior of the degrees of robustness at both resolutions agrees with the expectations in most cases if the in‐degrees or in‐ to out‐degrees decrease, the nodes become less robust.
