-> This branch is under active development!
-> 
-> Version 2 of `evogym` aims to make the following improvements:
-> - Separation of requirements between core `evogym` library and `examples`
-> - Modernize requirements (python, gym, numpy)
-> - Pip-installable, with wheels for common builds
-> - Tests

 Evolution Gym is a large-scale benchmark for co-optimizing the design and control of soft robots. It provides a lightweight soft-body simulator wrapped with a gym-like interface for developing learning algorithms. Evogym also includes a suite of 32 locomotion and manipulation tasks, detailed on our [website](https://evolutiongym.github.io/all-tasks). Task suite evaluations are described in our [NeurIPS 2021 paper](https://arxiv.org/pdf/2201.09863).
