stack genetic programming test

This is an exercise to use Stack GP for a simple symbolic regression task. If you want to get familiar with Genetic Programming in a few minutes, read GP.md

Crates used

rand is used as an RNG
rayon is used to use multiple threads and thus higher performance
clap is used to parse command line arguments. You can specify the population and other hyper parameters

Known issues

It seems that on some computers, rayon detect 2 processors rather than 4. There are actually 2 processors but the CPU supports 4 threads. This technology is known as hyper threading. To overcome this, you might want to specify number of processors used manually in the code.

What SR problem does it solve?

f(x) = 2 * x * x

Since this software is written in Rust, is it idiomatic?

I've tried but I'm not a Rust expert, yet.
