with Standard_Complex_Laur_Systems; use Standard_Complex_Laur_Systems; with Symmetry_Group; use Symmetry_Group; function Symmetric_Randomize ( p : Laur_Sys; v,w : List_of_Permutations ) return Laur_Sys; -- DESCRIPTION : -- This function returns a polynomial system with the same Newton -- polytopes, but with randomly generated coefficients, w.r.t. to -- the symmetry relations given by v and w. -- ON ENTRY : -- p a polynomial system with n equations in n unknowns; -- v,w representations of the symmetry group. -- ON RETURN : -- a symmetric randomized polynomial system.
