Sorry, but your question is simply too vague to answer. There are many global 
algorithms supported by nlopt. Which one(s) did you try? What do you mean by 
“invalid”?

Perhaps you need to read the wiki, which was what I used to get started. Can 
you implement a program which solves the problem on the tutorial page and get 
the same result? Try different algorithms with it as well.

The Algorithms page is also very useful.

Hi,

I wanted to ask if someone has a small sample or tutorial example which uses 
Global optimization algorithm. It would be very helpful as I am trying to use 
it but it keeps saying invalid. I just want an easy sample program as in the 
documentation of the NLOPT site there is only example which uses derivatives. 
It would be very helpful if anyone could share the sample program.

Thanks
