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. http://ab-initio.mit.edu/wiki/index.php/NLopt_Tutorial The Algorithms page is also very useful.

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.
