In a recent publication, the authors developed an algorithm for the computation of upper bounds on the restoration entropy for nonlinear systems. In a computational example for the Lorenz system, there was an error in the code that resulted in too low upper bounds. Indeed, we computed an upper bound lower than the theoretical value, published contemporaneous with our paper. We corrected the error and performed the computations again. Furthermore, we additionally used our method to compute an optimal Lyapunov-like function for the matrix from the theoretical derivation and present the results.
