About

Genetic programming helpers & strategies (tree based & multi-expression programming).

This package does not (yet) provide a complete GP framework and is largely focused on the following operations:

• General GP setup configuration
• Genotype / chromosome / AST generation
• Phenotype / chromosome translation
• Offspring generation
  • Crossover (single-point, uniform)
  • Mutation

Does not specifically deal with:

• Population management
• AST evaluation
• Fitness computation

• Evolutionary failures (blog post)
• Multi Expression Programming (Oltean, Dumitrescu)

Status
