How can I run GA without using Optimization tool box

I asked about Ga before and I got an answer. http://www.mathworks.com/matlabcentral/answers/262573-how-can-i-solve-minlp-optimization-using-ga

My question is that I want to run this code without using Optimization tool box.

function F = fitm(x)
q = reshape(x(1:6),3,2);
k = reshape(x(7:12),3,2);
m = reshape(x(13:end),3,1);
intcon = 13:15;
lb = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1];
ub = [inf, inf, inf, inf, inf, inf, 1, 1, 1, 1, 1, 1, inf, inf, inf];

%Const
A =0;
B = 0;

J = 2;
I = 3;
a = [3 2; 3 1; 1.1 9];
d = [1850 2000; 3000 2100; 1300 900 ];
hr = [2.4 1.3; 3.8 4.5; 3.6 4.2];
so = [3.5 1.5; 2.5 0.3; 0.6 6.3];
t = [1 1; 3 1; 1 3];
E = [2 2; 3 2; 2 3];
Y = [3 3; 3 3; 3 3];

S=100;
hv = [3.5; 4; 5];
C = [1; 5; 2];
Cv = [2.4; 3; 2;];
Cf = [3; 1.2; 2;];
s = [0.3; 0.1; 0.2;];
the = [0.01; 0.03; 0.02];
P = [1000; 8000; 9000];

dv = [sum(d(1,:)); sum(d(2,:)); sum(d(3,:))];
Q = [sum(q(1,:)); sum(q(2,:)); sum(q(3,:))];

 for i=1:I
     A = A + (S*dv(i)/(Q(i)*m(i))+(hv(i)*Q(i)*((m(i)-1)*(1-dv(i)/P(i))+dv(i)/P(i)))/2+...
    dv(i)*(C(i)*m(i)+m(i)*Q(i)*Cv(i)+Cf(i))/(Q(i)*m(i))+(s(i)*m(i)*dv(i)*Q(i)*the(i))/2);
    for j=1:J
    B = B + (a(i,j)*d(i,j)/q(i,j)+(hr(i,j)*((1-k(i,j))^2)*q(i,j))/2+...
    k(i,j)^2*so(i,j)*q(i,j)/2+(m(i)*t(i,j)*d(i,j))/q(i,j)+(m(i)*E(i,j)*d(i,j))/q(i,j)+...
     Y(i,j)*d(i,j));
 end
 end

 F = A + B;
 x = ga(F,15,[],[],[],[],[],lb,ub,intcon);
 disp(x)
 end

It is worked using GA Optimization tool box.

I added ' x = ga(F,15,[],[],[],[],[],lb,ub,intcon);' However, matlab shows me 'Not enough input arguments. Error in fitm (line 2) q = reshape(x(1:6),3,2);' How can I fix it...?

Your question "How can I run GA without using Optimization tool box" does not make sense to me, given that your stated question is about an error in your fitness function. I suggest that you edit your post.

The problem is that you put the ga call inside your fitness function call. You also put the lower and upper bounds inside your fitness function. These lines do not belong there. Take the lines

 lb = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1];
 ub = [inf, inf, inf, inf, inf, inf, 1, 1, 1, 1, 1, 1, inf, inf, inf];
 intcon = 13:15;
 x = ga(F,15,[],[],[],[],[],lb,ub,intcon);

out of your fitness function. Then, to call ga at the command line, enter the following at the command line

 lb = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1];
 ub = [inf, inf, inf, inf, inf, inf, 1, 1, 1, 1, 1, 1, inf, inf, inf];
 intcon = 13:15;
 x = ga(@fitm,15,[],[],[],[],[],lb,ub,intcon);

The difference is between a fitness function and the procedure to minimize the function. You have to separate these things.

Good luck,

Thank you, I got a result.

But,I saw some code that the ga call inside m-file within function. Is it a different case of mine?
