+If post processing is activated, it is performed after every +optimization run and it may be triggered using the solutions of the last optimization run by +the "Post process" button. +Post processing performs an initial clustering of the solutions with the given sigma interval (density-based clustering), +and on the set of best representative solutions from all clusters it performs a hill-climbing run for refinement. +After the HC step the set is clustered again to filter out solutions which converged during the HC. +
++The results of the post processing are displayed in the text window (and/or stats output file) and show a coarse +distribution of the final solutions as well as the explicit vectors of the n best solutions obtained, where n +is set as printNBest parameter. +If post-processing is started several times in a row, the initial solution set is the same, namely the one found +by optimization. Thereby one can guess, e.g., how close the solutions are to each other and how closely they +have converged during optimization itself. +
