You can find how to use nlopt to sovle the problem by using nonlinear programming. This is equivalent to minimizing the function f(x)=−g(x). He's also tried std::numeric_limits::max(), but NLOPT then takes that ridiculous number literally and it screws up the derivative estimates. The latest release can be downloaded from the NLopt releases page on Github, and the NLopt manual is hosted on readthedocs.
