I have a problem with my optimization code. I enter this code in matlab:

function Prob = objective_function()

rng default

% Indices

k = 15;

j = 2;

f = 10;

l = 5;

r0 = 6;

r = 6;

% Parameters

cr0 = randi([0 1],1,r0);

dr0f = randi([0 1],r0,f);

csl = randi([0 1],1,l);

cpjk = randi([0 1],j,k);

corj = randi([0 1],r,j);

pr0f = randi([0 1],r0,f);

cvjrk = randi([0 1],j,r,k);

% Objective Function

cb = zeros(r0,f);

cd = zeros(r,j);

cor = zeros(r0,f);

cr = zeros(j,k);

ctr = zeros(1,l);

cp2 = zeros(j,r,k);

for ii = 1:r0

    for jj = 1:f
        cb(ii,jj) = cr0(ii).*dr0f(ii,jj);
    end

end

for ii = 1:r

    for jj = 1:j
        cd(ii,jj) = corj(ii,jj);
    end

end

for ii = 1:r0

    for jj = 1:f
        cor(ii,jj) = pr0f(ii,jj);
    end

end

for ii = 1:j

    for jj = 1:k
        cr(ii,jj) = cpjk(ii,jj);
    end

end

for ii = 1:l

ctr(ii) = csl(ii);

end

for ii = 1:j

    for jj = 1:r
        for kk = 1:k
            cp2(ii,jj,kk) = cvjrk(ii,jj,kk);
        end
    end

end

obj = sum([cb(:);cd(:);cor(:);cr(:);ctr(:);cp2(:)]);

Prob.obj = obj;

disp(obj);

Prob.k = k;

Prob.j = j;

Prob.f = f;

Prob.l = l;

Prob.r0 = r0;

Prob.r = r;

Prob.cr0 = cr0;

Prob.dr0f = dr0f;

Prob.csl = csl;

Prob.cpjk = cpjk;

Prob.corj = corj;

Prob.pr0f = pr0f;

Prob.cvjrk = cvjrk;

Prob.cb = cb;

Prob.cd = cd;

Prob.cor = cor;

Prob.cr = cr;

Prob.ctr = ctr;

Prob.cp2 = cp2;

Prob = obj;

end

I want to solve this problem with genetic algorithm but when I use optimization toolbox and select 'ga' for solving the model, then I encounter with ' Too many input arguments' error. Whereas when I solve this problem with 'Linprog', I haven't receive any error. How I can solve this problem with ga?

The ‘objective_function’ function does not take any input arguments, and it needs at least to take the vector of parameters you are optimizing as an input.

Not problem.You are one of the best members of this site and I am very thank you for your attention.

I thought that asking question in this site has restriction in terms of numbers because in last time that I asked a question nobody answered me and I had to remove my question.

I very much appreciate your compliment!

There are no restrictions on the numbers. The more clearly you describe your problem and the question you would like to be answered, the better your chances will be to getting an answer. Also, it is quite possible that no one who saw your Question felt that they had the relevant knowledge to reply with an answer.

I am not in any way suggesting that the way you asked your Question was the problem,. however TUTORIAL: how to ask a question (on Answers) and get a fast answer may offer some suggestions on how best to construct it.
