gamultiobj--Too many input arguments.

Hi guys,

I am using gamultiobj to optimize three aims at the same time.

The parameters including the aim function, the linear inequalities and equalities and nonlinear constraint function are defined strictly according to the gamultiobj syntax.

But when I run the file, matlab always indicates:

Error using gamultiobj Too many input arguments.

I am using the MATLAB 2013a version.

Anyone's helps are appreciated very much!

Thanks very much!

Cheers

Dear Walter,

The followings are the codes related to the constrained MOGA:

options_moga = gaoptimset(@gamultiobj) ;

options_moga = gaoptimset( options_moga , 'Tolfun' , 1e-2 , 'TolCon' , 1e-2 , 'StallGenLimit' , 200 ) ;

AIM = @(XX)force_aim1( XX ) ; 

nonliear_constraint = @(XX)physical_constraints( XX )  ;    

[  force_and_torque , aim_value , exitflag,  output , population, score   ] = gamultiobj( AIM  , 9   , ...
                                                                                              A_inequation , power_constraint , ...
                                                                                              AEQ_modify   , BEQ_modify  , ...
                                                                                              lower_bound  , upper_bound , ...
                                                                                              nonliear_constraint , options_moga )

THANKS so much!

In R2013a, gamultiobj() did not accept nonlinear constraints.

http://www.mathworks.com/help/releases/R2013a/gads/gamultiobj.html

Those became available in R2014b

[Tony Cheng]

Thank u Walter! I will try to use 2014b.

But it seems not easy to get it...

But still thx u for your help!

If you have a license for at least R2014b already, then visit https://www.mathworks.com/mwaccount and click on your license and click to download and then on the right hand side of that, you can choose the version you want to download.
