Indeed it was not easy to get the thing converted. I will apply all the tests I already wrote for CMA-ES (they could be refactored out in a separate class later). The last two bugs I detected resulted only in a slight performance decrease and were only detected by debugging both programs in paralle

During experiments with space flight trajectory optimizations I recently observed, that the direct optimization algorithm BOBYQA http://plato.asu.edu/ftp/other_software/bobyqa.zip from Mike Powell is significantly better than the simple Powell algorithm already in commons.math ­ it uses significant
