Tournament selection introduction

Tournament selection is a strategy that pits chromosomes against one another in a tournament. While selections are still based on fitness, tournament selection introduces a strategy to choose parents that are both diverse and strong.

Tournament selection works like this:

  1. Choose a pool of n chromosomes where n is the “tournament size.”

  2. Choose the fittest chromosome from the tournament.

  3. Repeat.
