Decline of physical efficiency with random edge removal.
(A) Ensemble average of the ratio of the physical efficiency of damaged networks to the physical efficiency of the original network, as a function of the edge fraction removed. The efficiency of the vasculature networks declined more rapidly than that of the fungal networks. (B) The drop-off in physical efficiency was approximated for each network as the slope of a linear fit to Ep(f)/Ep(0) vs. f, computed between f = 0 and f = 0.1. There was a positive correlation between the slope and the relative wiring of the networks. (C) An example of a network from P.V. 2, where the red lines correspond to a random selection of f = 0.15 of the total number of edges, and the gray lines correspond to the remaining edges in the network. (D) An example of a network of a mouse vasculature system, where the red lines correspond to a random selection of f = 0.15 of the total number of edges, and the gray lines correspond to the remaining edges in the network.
