Evaluation metrics of node centrality.

Names	Abbreviations	Equations
Degree centrality	DC	$C_d\left(v\right)=\frac{deg\left(v\right)}{n-1}$
Betweenness centrality	BC	$C_b\left(v\right)=\frac{{\sum }_{s\ne v\ne t\in V}\frac{{\delta }_{st}\left(v\right)}{{\delta }_{st}}}{(n-1)(n-2)∕2}$
Closeness centrality	CC	$C_c\left(v\right)=\frac{{\sum }_{t,v\in V}{d}_G(v,t)}{n-1}$
Eigenvector centrality	EC	$C_e\left(v\right)={\lambda }^{-1}{\sum }_{t=1}^N{a}_{vt}{e}_t$
Current flow closeness centrality	CCC	$C_{cc}\left(v\right)=\frac{n-1}{{\sum }_{v\in V\wedge v\ne t}\left(p_{st}\left(v\right)-p_{st}\left(t\right)\right)}$
Load centrality	LC	$LC\left(v\right)={\sum }_{s,d\in V}{\theta }_{s,d}\left(v\right)$
