Multi-objective Optimization with Genetic Algorithm - A MATLAB Tutorial for Beginners

In this tutorial, I show implementation of a multi-objective optimization problem and optimize it using the built-in Genetic Algorithm in MATLAB. The given objective function is a simple function that helps a beginner user to understand the basic concept of optimization in MATLAB easier. The given objective function or fitness function has one input variable and two outputs. I write two separate functions one for the fitness function and one for the main algorithm. I plot the pareto-front that illustrates the obtained solutions in a proper way.
