The calculations were performed using StatSoft Statistica (version 13.3.721.0) and Microsoft Excel (version 2301, build 16026.20146). The results were analyzed using standard options in Statistica's DoE module. The RSM (Response Surface Methodology) method was used for calculations. Optimal conditions were determined using the Solver add-in in Excel. The nonlinear generalized reduced gradient method (GRG) was used, analyzing the central derivatives with the multi-start option for at least 10,000 populations.
