WebAug 1, 2024 · It is often claimed that the entropy of a network’s degree distribution is a proxy for its robustness. Here, we clarify the link between degree distribution entropy and giant component robustness to node removal by showing that the former merely sets a lower bound to the latter for randomly configured networks when no other network …

WebThe network structure of the ECSs is constructed according to the graph theory [36,37] and compared based on the structure entropy method (SEM) from the perspective of timeliness and quality of information transmission. This study is conducive to the comparison of the performance of different ECSs, and can reduce the development period and cost ...
WebIn order to prove most of our claims we will need to appeal to some well-known facts and results from graph theory. Here we provide the necessary background. A graph, Γ, is a mathematical structure consisting of a set of vertices, and a set of edges connecting the vertices. If two vertices g and h are adjacent (connected) then we denote that ...
