    <p>The PPL implements the following function:<br>
    </p>
    <p>bool<br>
      check_containment(const NNC_Polyhedron& ph,<br>
                        const
      Pointset_Powerset<NNC_Polyhedron>& ps);<br>
    </p>
    <p>It returns true iff ph is contained in the union of the polyhedra
      in ps.<br>
    </p>
    <p>There also is a variant where the argument polyhedra are
      topologically closed, but the underlying implementation will
      anyway resort to using NNC_Polyhedron.<br>

      <div dir="ltr">Hi, I've been trying to merge or perform union on
        polytopes using poly_hull_assign and upper_bound_assign, but
        they return poly hull of the resulting polytopes. For my use it
        would not give accurate results. difference_assign also returns
        a poly hull. Is there a way that I can find out containment of a
        polytope in multiple polytopes? Your help would be highly
        appreciated.<br>
