Answer 1

[Walter Roberson]

You constructed your own main_AFO file.m file, probably based upon the main1.m in the File Exchange contribution.

The main1.m source code has

[lb,ub,dim,fobj] = Get_Functions_details(option.F);
%stuff
option.fobj0=fobj;
option.fobj=@fitFCN_BX;

I suspect that you instead did

options.fobj = @fobj;

but that you instead should have done

option.fobj0 = @fobj;
option.fobj=@fitFCN_BX;

Unfortunately once again someone has asked us to debug code without providing us with a copy of the code, so we can only guess about the details.

[tahseen alshmary]

Sorry

The code is

addpath('benchmark functions')
% Problem preparation 
option.dim = 14;
option.ub = 1.1*  ones(1,option.dim);
option.lb = 0.05* ones(1,option.dim);
option.fobj = @ofun;
option.maxIteration=1000;   %number of iteration
option.numAgent=10;            %number of dingoes that will attack
% µÛÆó¶ìËã·¨

You need to replace

option.fobj = @ofun;

with

option.fobj0 = @ofun;
option.fobj = @fitFCN_BX;

I cannot reproduce your issue. When I try the following, I do not get an error:

x = randn(20,1);
r = ofun(x)

r = 3.5276e+05

function f = ofun(x)   % objective function (minimization) 
of =2.6773*x(1)+3.1007*x(2)+3.2178*x(3)+ 3.8021*x(4)+3.6727*x(5)+3.0442*x(6)+1.6362*x(7)+3.0479*x(8)+3.3917*x(9)+3.7468*x(10)+3.8989*x(11)+3.1073*x(12)+3.3207*x(13)+ 1.6382*x(14);

where can I put this

x = randn(20,1);

r = ofun(x)

[Walter Roberson]

The problem has to do with the (Emperor Penguin) optimization interface being used to call the function; it expects to call a function with three parameters, not a function with one parameter.

[tahseen alshmary]

So , How can I solve it .
