It is possible; in that case, you would have to re-write the step 3 (Utopia line vector) and step 5 (utopia linea points) accordingly to your desired number of objectives. When dealing with more than 3 objectives, I use usually an evolutionary algorithm instead of the NNC; a local optimization routine could be always used at the end of the evolutionary optimization process, to improve convergence.

using this matlab code could it be possible to handle more than 3 objectives. if so, how this could be done.

i am getting an answer shown below while running MODEparam.m file. can anyone solve this

??? Error using ==> CostFunction> myfile at 74
The specified M-File 'myfile' in myfile/S-Function' is not a valid Level
1 S-Function. The number of input and/or output arguments is not valid. A likely cause for
this error is that the name of a level-2 M-file S-function has been specified in this block
(which supports only level-1 M-file S-functions). Use the 'Level-2 M-file S-Function' block
from the Simulink library.
