This course has been designed to introduce you to a field of programming you might have never been exposed to. In this course, you’ll learn everything you need to know to start working with genetic algorithms. As you work through the course, you’ll build a framework for problems using genetic algorithms. By the end, you’ll have a full-featured, customizable framework complete with statistics, genealogy tracking, and more, and you’ll have learned everything you need to solve practical problems with genetic algorithms.

Genetic Algorithms in Elixir

## Overview of hyperparameters

In machine learning, **hyperparameters** refer to the parts of the algorithm we set before the algorithm starts training. Internally, the algorithm learns parameters that help it perform a task. Externally, the programmer controls parameters that dictate how the algorithm trains.

In the context of genetic algorithms, hyperparameters refer to things we choose before running the algorithm,  like population size, mutation rate, and so on.

Because hyperparameters can have a huge impact on the outcome of our algorithms, it’s important to be able to rapidly change them. To ensure we can change hyperparameters without too much of a headache, we need to implement a simple configuration mechanism into the framework that separates the hyperparameters from the overall structure of the algorithm.


## Adding hyperparameters to our framework

To start, change the signature of both `run/3` and `evolve/4` to accept an additional parameter:
