pyoperon 0.6.1

Python bindings for the Operon symbolic regression library

pyoperon

pyoperon is the python bindings library of Operon, a modern C++ framework for symbolic regression developed by Heal-Research at the University of Applied Sciences Upper Austria.

A scikit-learn regressor is also available:

from pyoperon.sklearn import SymbolicRegressor

The example folder contains sample code for using either the Python bindings directly or the pyoperon.sklearn module.
