i have this coding, i want to have make a loop of for 10 iteration.. the curent coding didnt give me 10 iteration..
i want to have 10 possible solution however its only show 1 solution. below is the coding. what can i do to make it generate 10 solution
%read data
clc
clear
%global f d;
%flow
f=[ 0 5 2 4 1
5 0 3 0 2
2 3 0 0 0
4 0 0 0 5
1 2 0 5 0];
%distance
d=[ 0 1 2 3 1
1 0 1 2 2
2 1 0 1 3
3 2 1 0 4
1 2 3 4 0];
[r,c]=size(f);
max_i= r;
max_j =r;
max_k= r;
max_q= r;
A=zeros(r,r);
ID=randperm(r);
MaxIt=10;
x=zeros(r,r);
n=length(ID);
x1=ID;
for i=1:n
for j=1:r
x(j,x1(j))=1;
B(i).mat=x; %store permutationof binary value, 0,1
end
x=zeros(r,r);
end
for i=MaxIt
for no=1:length(B)
z=0;
xa=B(no).mat;
for i=1:max_i
for j=1:max_j
for k=1:max_k
for q=1:max_q
z= z+ f(i,k).*d(j,q).*xa(i,j).*xa(k,q);
end
end
end
end
end
no;
F(no,:)=[no z];
end
zmin=min(F(:,2));
ii=find(F(:,2)==zmin) ;
x_initial = B(ii).mat;
xbin= B(ii).mat
z_minimum = zmin
%disp(B(ii).mat)
%fprintf (B(no).mat);
%disp(z)

Quadratic Assignment Problem using GA
I'm not familiar with the topic above, do you have pseudocode for it? or any reference for me to see? Where do you find reference to write your code?
Perhaps they will help me to understand more.
