conductance#
- conductance(G, S, T=None, weight=None)[source]#
Returns the conductance of two sets of nodes.
The conductance is the quotient of the cut size and the smaller of the volumes of the two sets. [1]
- Parameters:
- GNetworkX graph
- Scollection
A collection of nodes in
G
.- Tcollection
A collection of nodes in
G
.- weightobject
Edge attribute key to use as weight. If not specified, edges have weight one.
- Returns:
- number
The conductance between the two sets
S
andT
.
