networkx.mixing_expansion¶

networkx.mixing_expansion(G, S, T=None, weight=None)[source]¶

Returns the mixing expansion between two node sets.

The mixing expansion is the quotient of the cut size and twice the number of edges in the graph. [1]

Parameters:	G : NetworkX graph S : sequence A sequence of nodes in G. T : sequence A sequence of nodes in G. weight : object Edge attribute key to use as weight. If not specified, edges have weight one.
Returns:	number The mixing expansion between the two sets S and T.
