networks[acycpoly] - acyclicity polynomial of an undirected graph

Calling Sequence

acycpoly(G, p)

Parameters

G

-

undirected graph or network

p

-

variable in acyclicity poly (usually edge probability)

Description

• 

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

• 

The acyclicity polynomial in variable p gives the probability that G is acyclic when each edge operates with probability p.

• 

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