I don’t see how this advances the discussion. It is hardly any more specific than the vague question you posted earlier. There has already been quite a bit of effort at building the CRAN Task Views and the Optimization Task View should have popped up with any sort of effort on your part:


Any sort of specific response will require that you provide …… specifics.
