Dear all,
I know it is a long shot, anyway, here is my problem.
I use NLopt from the C++ interface on Linux. The optimizer is:
nlopt::LD_LBFGS.
Everything worked perfectly until I changed the function to be optimized
to use OpenMP and BLAS.
Now seems I have conflicts between OpenMP and my BLAS library (not
related to NLopt, I hope).
My problem is that NLopt raises the generic exception "nlopt failure"
when the gradient vector contains -Inf values.
Is there a more precise error reporting mechanism in NLopt or should I
rely on printf statements in my function?
Thanks for your help!
mario
P.S.: and many thanks for NLopt. It is really useful.
