2.3.1 Fragmentation of the network
We computed the fragmentation F of the static network, which
measures the proportion of pairs of nodes for which no connecting path
exists (no direct or indirect connections between premises). The value
can be calculated through an assessment of the number and size of
components in the network, where a connected component \(C\) is defined
as a subset of nodes \(V\), where \(C\subseteq V\) for which a path
exists between any pair of nodes in C. Thus, fragmentation
was calculated as:
