Optimization with Genetic Algorithm – A MATLAB Tutorial for beginners

In this tutorial, I will show you how to optimize a single objective function using Genetic Algorithm. We use MATLAB and show the whole process in a very easy and understandable step-by-step process.

For a tutorial on Constrained Optimization with Genetic Algorithm see this video: https://www.youtube.com/watch?v=esGZtl3gIlY&feature=youtu.be

I want to write a Genetic Algorithm in Matlab to find the maximum value of f(x)=15x-x^2 where parameter x varies between 0 and 15. and x takes only integer values. and besides, i want to find that x which f(x) has the maximum value.
set up problem variables are:
search space=2^4=16
initial population: N=6
pc=0.7
pm=0.01
number of generation=20
The number of generation is the termination criterion for GA.
I use one gene for crossover and mutation.
i wrote these lines now :
fitnessfunc=15*x-x^2;
initialpop=6;
pc=0.7;
pm=0.01;
generation=20;
x=[];
y=repmat(x,1,4);
for i=1:6

I will be very grateful for your helpful suggestions and advice.
thanks

Nice explanation, But the fval should be around 0.04 not 2.43. Do you know why?

does the same code works in 2011

AHMED ABDELFATAH Mostafa says:

Thank you for this effort. Simple and great.
If you don’t mind I need to ask you some questions, would you please send me your email.
