Hi!
I am using the NLOPT_GN_DIRECT optimizer.
I am pretty happy with the optima it provides me, but I am surprised
to see that the return code is NLOPT_FAILURE.
Looking at the source files of direct does not help me very much at
first sight.
NLOPT_FAILURE is returned at two different location in cdriect.c,
divide_rect() function. Is there any simple intuition of the reason
leading to this return code?
Thanks for any help,
Philippe
