grinpy.invariants.disparity.inverse_disparity(G)

Return the inverse disparity of the graph.

The inverse disparity of a graph is defined as:

\[\sum_{v \in V(G)}\frac{1}{disp(v)}\]

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

Parameters:G (NetworkX graph) – An undirected graph. Returns:The inverse disparity of the graph. Return type:float
