conductance

conductance(G, S, T=None, weight=None)

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 and T.
