SOPPI proved to be an efficient optimisation approach with fast convergence within only a few iterations but had a strong tendency to get trapped in a local minimum for multimodal functions. Thereby, the optimisation performance was susceptible to the selected step length. In optimising reactive force fields with the SOPPI approach, a deeper understanding of the respective parameters and their optimisation range is required. However, it enables the user to gradually follow and retrace the optimisation process and thus facilitates the re-optimisation of the parameter set.
