A genetic algorithm that finds the best arrangement of crops in Minecraft, written in Rust.
Knowing that crops grow fastest when crops of the same type are not diagonally adjacent, an arrangement of crops for a given rectangle is scored based on how many crops meet those criteria, and then the best crops survive each iteration unchanged, the worst "die" (are replaced by random arrangements), and inbetweens are mutated (one extra change added).
See src/main.rs to see and edit the parameters, then do:
$ cargo run --release
