Eevee + AST? = Expreon!!
A set of crates to implement Symbolic Regression using Genetic Programming (GP) in rust.

---

NOTE: This is a work in progress, I'm implementing this as the GP engine for another project.

This library implements a set of primitives to implement Symbolic Regression using Genetic Programming (GP) techniques in rust in the form of multiple independent reusables crates:

• crates/expreon_ast: Provides the arena-allocated AST expression machinery (independent of the evaluation engine)

• crates/expreon_eval: Provides the evaluation runtime for expressions, operations and a set of operations built-in.

• crates/expreon: The library crate that wraps both crates and provide GP primitives to implement SR along with a library of mutations built-in.

Where does that name come from?????

I like eevee (the cute pokemon), and eevee is a pokemon that evolves a lot (DNA mutations) -> like in GP where individual solutions are mutated and bred. Hence the name expreon.

This is inspired by the Operon C++ framework which implements Symbolic Regression with optimization of model coefficients using the Levenberg-Marquardt algorithm.
