Deep Neuroevolution: Genetic Algorithms Are a Competitive Alternative for Training Deep Neural Networks for Reinforcement Learning

Paper summary

A simple Deep GA evolves fixed-topology neural parameters using truncation selection, additive Gaussian mutations and elitism, omitting crossover for simplicity. A network with more than four million parameters achieves competitive results on selected Atari benchmarks. The paper discusses unequal frame budgets and evaluation-start conventions among some external comparisons. This establishes a useful mutation-only baseline, but contains no ablation showing crossover would worsen that GA.

Relevance to the project

Assistant interpretation: mutation-only evolution is a substantive baseline when assessing whether recombination of inherited neural rules earns its complexity and evaluation cost. Fixed action-policy weights are distinct from lifetime-plastic F/H weights and inherited type controllers.

Genetic representationsLearning and adaptationEvaluation methods

Older benchmark-specific comparisons, five Atari runs and heterogeneous external settings; the current review does not audit all experiments or supplement. Success without recombination does not establish its inferiority.
