Dear All, I am using using Nelder Mead as the optimization algorithm but when I run the optimization it is seen that the Objective is the same in the objective table. i.e it is not minimizing the objective function. Any help in this regard is appreciated. Regards Mahima

You might have badly scaled controls. Alternatively, try replacing the optimization study step with a sweep over the parameters to verify that the controls actually affect the objective.
