package BKK_Bound_Computations is

-- DESCRIPTION :
--   This package exports some routines for computing the BKK bound
--   and solving a random coefficient system by polyhedral continuation.
--   These function are black box routines: the user does not have to
--   worry about intermediate data structures.

  function BKK_by_Implicit_Lifting ( file : file_type; p : Poly_Sys )
                                   return natural;
  function BKK_by_Static_Lifting ( p : Poly_Sys ) return natural;
  function BKK_by_Static_Lifting ( file : file_type; p : Poly_Sys )
                                 return natural;
  -- DESCRIPTION :
  --   If a file is specified, then the mixed subdivision will be written
  --   on that file.  Either implicit or random static lifting can be used.

  -- DESCRIPTION :
  --   If a file is specified, then intermediate results will be written
  --   on that file.  Either implicit or random static lifting can be used.
