Genetic Algorithms Aren't Magic—Here's Why They Actually Work (and When They Don't)

Evolution doesn't need calculus. Genetic algorithms solve problems computers usually can't—by copying nature's trick: vary, select, repeat. Here's how they actually work.

⚡ Key Takeaways

  • Genetic algorithms solve optimization problems without gradients by simulating evolution: variation, selection, and mutation. 𝕏
  • They're invaluable for discrete, permutation-based problems like routing and scheduling where traditional calculus fails. 𝕏
  • They're not sexy, not new, and not guaranteed optimal—but they're honest, practical, and used at scale by logistics companies worldwide. 𝕏
