Abstract
This
paper discusses analytic algorithms and software for the
enumeration of all integer flows inside a network. Concrete
applications abound in graph theory, representation theory, and
statistics. Our methods are based on the study of rational functions
with poles on arrangements of hyperplanes; they surpass traditional
exhaustive enumeration and can even yield formulas when the input data
contains some parameters. We also discuss the calculation of chambers
in detail because it is a necessary subroutine.
