Last Number in NLopt Result is Iterations or Function Evaluations?

[bdas123]

I used the NLopt sublibrary of Nonconvex.jl and flawlessly produced this result (thanks!).

Does the 7 at the end refer to the number of iterations or the number of function evaluations?

Hey! Sorry I just saw this issue. Yes the 7 is the number of times the functions were evaluated.

[mohamed82008]

Not the number of iterations
