Extraction from https://github.com/libprima/prima https://github.com/libprima/prima “There do exist "translations" of Powell's Fortran 77 code into other languages. 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.” See also https://github.com/stevengj/nlopt/issues/501 https://github.com/stevengj/nlopt/issues/501 , where the author of NLopt talks.
