I am trying to write a genetic algorithm code for my optimization problem, but when I run the code for loops are not executed! I don't get the reason. Any help would be appreciated.

part of my code from beginning to the end of second for loop is:

clc

clear all

% rand('state',0);

starttime=datestr(now);

total_t=180;

%----------------------------------GA Setup--------------------------------

% Setup the GA

%ff=fitnessV; % objective function

npar=3; % number of optimization variables

%

%-----------------------------Stopping criteria----------------------------

maxit=50; % max number of iterations

mincost=.01; % minimum cost

%

%--------------------Specifying the parameters of GA-----------------------

selection=0.5; % fraction of population kept

popsize=100;%size of the population

keep=selection*popsize;

M=ceil((popsize-keep)/2); % number of matings

odds=1;

for ii=2:keep

    odds=[odds ii*ones(1,ii)];

end

odds=keep+1-odds;

Nodds=length(odds);

mutrate=0.1; % mutation rate

%

%------------------------Creat the initial population----------------------

iga=0; % generation counter initialized

pop=rand(popsize,npar); % random population of continuous values

for ii=1:pop

for j=1:popsize

if pop(ii,j)>n || pop(ii,j)
