This repo will most likely no longer be extended.
Please take a look at genepro instead. genepro attempts to be an overall better version of a simple GP baseline in python, which goes beyond regression alone.
This Python 3 code is a simple implementation of genetic programming for symbolic regression, and has been developed for educational purposes.
numpy & sklearn. The file test.py shows an example of usage.
You can install it with pip using python3 -m pip install --user simplegp, or locally by downloading the code and running python3 setup.py install --user.
