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
The mixing expansion between the two sets
S
andT
.- Return type
