Tunafish is a high-level genetic algorithm/programming-based function auto-tuning toolkit. It figures out what the best arguments to a function should be to optimize its output with respect to an arbitrary fitness function, like a distance measure.
GeneticPromptLab uses genetic algorithms for automated prompt engineering (for LLMs), enhancing quality and diversity through iterative selection, crossover, and mutation, while efficiently exploring minimal yet diverse samples from the training set.
