Neuroevolution Basics and Purpose

  • Neuroevolution combines neural networks and evolutionary computation to evolve increasingly complex brain-like structures.
  • It aims to understand how complexity arises from simplicity without predefined guiding gradients.
INSIGHT

Genetic Algorithm Fundamentals

  • Genetic algorithms work by breeding and selecting genomes via mutation and crossover to improve fitness.
  • They automate the breeding process to evolve better solutions without human intervention.
INSIGHT

Neural Networks and Backpropagation

  • Neural networks use weighted connections between neurons to transform inputs into outputs.
  • Backpropagation adjusts weights by sending error signals backward to optimize network behavior iteratively.
