(Top) Average number of iterations and (middle) corresponding computing times of the PSO algorithm estimating different combinations of known a priori plasma parameters from the plasma line at different signal fluctuation percentages (\(\delta (\%)\)). Results were obtained from simulations with the parameter configuration (dash-dotted lines) “Param. 1” used by Wu et al. (2015) and (dashed lines) “Param. 2”. (Bottom) Boxplot of average computing times of simulations with different combinations of a priori plasma parameters using the configurations “Param. 1” and “Param. 2”
