 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](...).

Examples

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