• Documentation is poor. Have to look at code to understand and use properly.
• Margin analysis limited to binary search
• Releases are not consistent between windows/linux and source code lags releases
• Optimizer works in fixed step sizes and runs a sequence of single parameter optimizations.
  • Works well in certain cases, but returns far from optimal values in other cases.
