Evolutionary.jl
The package Evolutionary aims to provide a library for evolutionary optimization. It provides implementation of $(\mu/\rho \; \stackrel{+}{,} \;\lambda)$-Evolution Strategy, $(\mu/\mu_I, \;\lambda)$-Covariance Matrix Adaptation Evolution Strategy, Genetic Algorithm, and Differential Evolution as well as a rich set of mutation, recombination, crossover and selection functions.
Getting started
To install the package just type
