# grinpy.invariants.disparity.inverse_disparity¶

grinpy.invariants.disparity.inverse_disparity(G)

Return the inverse disparity of the graph.

The inverse disparity of a graph is defined as:

$\sum_{v \in V(G)}$

rac{1}{disp(v)}

where V(G) is the set of nodes of G and disp(v) is the disparity of the vertex v.

G : graph
A Networkx graph.
inverseDisparity : float
The inverse disparity of the graph.
