NET wrapper for Prof. A header-only wrapper library for calling NLopt optimization in a single line using Eigen::VectorXd Topics For example, NLopt contains a C version of COBYLA, NEWUOA, and BOBYQA, but the C code in NLopt is translated from the Fortran 77 code straightforwardly, if not automatically by f2c, and hence inherits the style, structure, and probably bugs of the original Fortran 77 implementation.
