Hi everyone, Thank you for the help, I apologize for not "providing commented, minimal, self-contained, reproducible code." I was looking for some pointers about how to do this in general, but it would have been helpful for me to post a specific example. Anyway, after the feedback this is the solu

Please allow me to clarify my original question. What I really need to be able to do it is to take arbitrary functions and evaluate them for arbitrary parameter values. I'm doing the optimization myself, so I need to be able to take a user's function and evaluate them at the current parameter value
