npm downloads

This project is part of the @thi.ng/umbrella monorepo.

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
