    Source documentation

    A parent at any of the k replacement stages, with all of its actual children bounded by the specified multiple of its own slope. The recursion restricts to old vertices and therefore includes every stage, not just the last one.

    def StableParent (c : ℝ) : (k : ℕ) → (Vertex k → X) → Prop
      | 0,_ => False
      | n+1,f => (∃ e : Edge n,∀ (i : ℕ) (b : Bool),
