+This improvement has been evaluated on a set of experiments.
+For 10 thresholds $t$, such that $1E-5 \le t \le 1E-3$, we have
+executed 10 times the approach detailed before either with the new
+gradient calculus or with the original argmin one.
+The Table~\ref{Table:argmin:time} summarizes the averages of these
+execution times, given in seconds. We remark time spent with the gradient
+approach is about 37 times smaller than the one of the argmin one.
+Among implementations of argmin approaches, we have retained
+the COBYLA one since it does not require any gradient to be executed.
