I currently working to find the optimal value from refrigeration system with multiobjective optimization using gamultiobj , i used two objective function and four decision variable:
- Exergy efficiency (i want this value to be maximum) - f(1)
- and Economic Cost (i want this value to be minimum) - f(2)
but when i run the optimization, the output value of the objective function are all the same.
i guess its because of the objective function, but i dont know how to fixed it. can you all please help me?
