EvoLP.jl is a playground for evolutionary computation in Julia. It provides a set of predefined building blocks that can be coupled together to play around: quickly generate evolutionary computation solvers and compute statistics for a variety of optimisation tasks, including discrete, continuous and combinatorial optimisation.

• Random population generators (vectors and particles)
• Parent selection operators
• Several crossover and mutation methods
• Test functions for benchmarking
• Convenient result reporting and a statistics logbook

Combine these blocks to make your own algorithms or use some of the included minimisers: GA, 1+1EA and PSO. Additionally, you can extend EvoLP to create new operators.

You can install EvoLP.jl from the REPL using the built-in package manager:

julia> import Pkg
julia> Pkg.add("EvoLP")

Alternatively, you can enter Pkg mode by pressing the ] key and then add EvoLP like so:

julia> ] # upon typing ], the prompt changes (in place) to: pkg>
pkg> add EvoLP

• Read the documentation.
• Browse some of the examples to see how to use the built-in algorithms.
• For a more comprehensive tutorial, read the 8-queens problem where we construct an algorithm from scratch.

Please report any issues via the GitHub issues tracker.
