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

# Adding tracking feature in our framework 

Before we can access the different statistics of evolution, we need to ensure our algorithm tracks them after every generation. To do this, we will have to implement a new function `statistics` that runs immediately after your population is evaluated and updates the statistics server appropriately.

Start by updating `evolve/4` in `lib/genetic.ex` to call `statistics/2`, like this:

def evolve(population, problem, generation, opts \\ []) do
  population = evaluate(population, &problem.fitness_function/1, opts) 
  statistics(population, generation, opts)
  best = hd(population)
  # ...
end

Next, we need to implement `statistics/3`. To customize the statistics we take between generations, we can accept a `:statistics` option in `opts`, which is a keyword list of functions that implement different calculations on the population. We’ll want to define a default suite of statistics so we don’t have to define these every time. Hence, implement `statistics/3` like this:
