Pretty interesting! I had thought about stuff like this on and off for a long time but this is the first time seeing something like this on HN. Very cool.
Thanks! Symbolic regression is the kind of thing that once you start using, you end up finding applications pretty much everywhere. It also performs better than neural networks in many common applications of machine learning, while being much simpler and more interpretable. The biggest exception are problems of image classification, where neural networks perform much better.
