I have only tested it with . On Unix, you would normally Oct 13, 2018 · Look careful at the example code: the objective function and the constraint functions are C functions, and the body of our example invokes C functions from NLopt. This user defined algorithm (UDA) wraps the NLopt library making it easily accessible via the pygmo common pygmo. hpp C++ header file to allow you to call it in a more C++ style). While the NLopt library supports Fortran by using implicit interface calling conventions, those are not type-safe.
