FlowPolynomial

FlowPolynomial[g,k]

gives the flow polynomial of the graph g.

FlowPolynomial[{vw,…},…]

uses rules vw to specify the graph g.

Details

  • FlowPolynomial[g,k] gives the number of nowhere-zero k-flows of g.
  • FlowPolynomial[g] gives a pure function representation of the flow polynomial of g.
