   paper we describe a variant of Sulzmann and Lu's algorithm: Our
   algorithm is a recursive functional program, whereas Sulzmann
   and Lu's version involves a fixpoint construction. We \textit{(i)}
-  prove in Isabelle/HOL that our program is correct and generates
+  prove in Isabelle/HOL that our algorithm is correct and generates
   unique POSIX values; we also \textit{(ii)} establish a finite
   bound for the size of the derivatives.
