- Genetic Algorithms (GAs) are members of a general class of optimization algorithms, known as Evolutionary Algorithms (EAs), which simulate a fictional environment based on theory of evolution to deal with various types of mathematical problem, especially those related to optimization. Also Genetic Algorithms can be categorized as a subset of Metaheuristics, which are general-purpose tools and algorithms to solve optimization and unsupervised learning problems.
In this series of video tutorials, we are going to learn about Genetic Algorithms, from theory to implementation. After having a brief review of theories behind EA and GA, two main versions of genetic algorithms, namely Binary Genetic Algorithm and Real-coded Genetic Algorithm, are implemented from scratch and line-by-line, using both Python and MATLAB. This course is instructed by Dr. Mostapha Kalami Heris, who has years of practical work and active teaching in the field of computational intelligence.
Components of the genetic algorithms, such as initialization, parent selection, crossover, mutation, sorting and selection, are discussed in this tutorials, and backed by practical implementation. Theoretical concepts of these operators and components can be understood very well using this practical and hands-on approach.
At the end of this course, you will be fully familiar with concepts of evolutionary computation and will be able to implement genetic algorithms from scratch and also, utilize them to solve your own optimization problems.
Topics covered in this part are listed below:
● Structure of GA Code in Python
● The Main Function of GA
● Initialization
● Keeping Track of Best Solution Ever Found
● The Main Loop
● Selecting Parents
● Performing Crossover
● Performing Mutation

I do always appreciate Dr. Kalami Haris for his powerful instructions in mathematics and metaheuristics.
Great coding, a bit quick paced but definitely followable and understandable. Thank you!
Dear Dr. Kalami, I hope you see this. I have learnt a lot from you in Faradars website and downloaded numerous courses (Multiple times since I forget my old emails and passwords ). I wanted to let you know that I appreciate the effort you make for making these outstanding courses.
Excellent!!!
thanks you very much
Sir how to implement multiple traveling salesman problem using NSGA-2 in python.
Can we modify this one for Knapsack/JobcShop problem? If yes how to modify this code for any function test and different parameters
Can we determine continuous decision variables (non-binary) with genetic algorithm?
I need different values of max and min for each variable. How can I do it?
You are awesomeeeeeeeeeeeeeeeeeeee!!!!!!
Is there a way to put constraints in the nvars like pop[1].position[0] - pop[1].position[1] should be greater than some value like in linear programming?

Instead of structure() could we use just python classes to define a class problem?
yeah i think python is not his main language, check the ; he puts in 4:11. :) you could just do these things with a class as well.
