I am sorry, I do not understand what you are asking. Perhaps you can 
include an example of the type of parameters you would like to include, 
and an example of the syntax you use to call your optimization function.

I have seen the documentation on how to pass parameters in the nonlinear constraints but not variables, is this possible?
