# networkx.algorithms.cuts.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
• 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 conductance between the two sets S and T.
