flowpoly

  

flow polynomial of an undirected graph

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

flowpoly(G, h)

Parameters

G

-

undirected graph or network

h

-

variable used in flow polynomial (usually a modulus)

Description

• 

Important: The networks package has been deprecated.  Use the superseding command GraphTheory[FlowPolynomial] instead.

• 

The flow polynomial in variable h gives the number of nowhere-zero flows on G with edge labels chosen from integers modulo h.

• 

This routine is normally loaded via the command with(networks) but may also be referenced using the full name networks[flowpoly](...).
