Implementing Common Selection Strategies

Explore common selection strategies in genetic algorithms such as elitism and random selection. Understand how to implement these strategies in Elixir, balancing genetic diversity and fitness to improve algorithm performance and avoid premature convergence.

Common selection strategies

Balancing genetic diversity with strong solutions can be difficult to achieve without a smart selection strategy. Fortunately, there are common selection strategies that are battle-tested and proven to work well for many different problem sets.

The selection strategies we’ll learn about in this course are the following:

  • Elitism selection

  • Random selection

  • Tournament selection

  • Roulette selection

We’ll see how these strategies work, what each of their drawbacks are, and how to implement them in Elixir so we can add them to your toolbox.

Elitism selection

Elitism selection is the simplest and most common selection strategy. The idea is simple: choose the best n chromosomes to reproduce. Elitism selection gives preference to ...
