Table 2. The employed distance measures.

Name	Type	Description
pGED	Normalized graph edit distance	Minimization of a sequence of morphological graph edit operations that are needed to make two networks isomorph [46].
	Kullback-Leibler divergence	Comparison of the degree distributions of two networks.
	Kullback-Leibler divergence	Comparison of the distance distributions of two networks.
	Kullback-Leibler divergence	Comparison of the sphere-based vertex probabilities of two networks.
	Kullback-Leibler divergence	Comparison of the distribution of the number of topologically equivalent vertices of two networks.

Here, we list the 5 distance measures that were used for the selection of a graph prototype.
