mixing_expansion(G, S, T=None, weight=None)¶
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. 
G (NetworkX graph)
S (sequence) – A sequence of nodes in
T (sequence) – A sequence of nodes in
weight (object) – Edge attribute key to use as weight. If not specified, edges have weight one.
