If I use a criterium like ftol_rel, nlopt does not seem to take the stopping criterium into account. On the other hand, if we tried to use the NLopt C++ interface which brings with it someinterface code we would require linking to that code (which R cannot easily Assume that you have cloned the NLopt GitHub repository in the following folder: C:\NLopt_src\nlopt. library for nonlinear optimization, wrapping many algorithms for global and local, constrained or unconstrained, optimization - nlopt/test/t_tutorial. x using derivative free algorithms, such as COBYLA, and inp is the input data. But it is intended behavior for others: stevengj/nlopt#279 (comment) So perhaps we just close this issue and deal with the consequences. Johnson" notifications@github.
