+- An additional use case reference for the Ackley function (as a metamodeling

 - The ten-dimensional inert function from Linkletter et al. (2006) with
   no active input variable whatsoever; the function was used in the context of
   sensitivity analysis.

 # Ackley Function
 
-The Ackley function  is an $M$-dimensional scalar-valued function.
-The function was first introduced by Ackley {cite}`Ackley1987`
-as a test function for optimization algorithms.
-Originally presented as a two-dimensional function,
-it was later generalized by Bäck and Schwefel {cite}`Baeck1993`.
+The Ackley function is an $M$-dimensional scalar-valued function.
+Introduced by Ackley {cite}`Ackley1987` as a benchmark function for
+global optimization algorithms, the function was originally presented in
+two dimensions.
+Bäck and Schwefel {cite}`Baeck1993` later generalized the function to higher
+dimensions.
+More recently, it was employed as a test function for a metamodeling method
+in {cite}`Kaintura2017`.
