ABSTRACT
QDax is an open-source library with a streamlined and modular API for Quality-Diversity (QD) optimization algorithms in jax. The library serves as a versatile tool for optimization purposes, ranging from black-box optimization to continuous control. qdax offers implementations of popular QD, Neuroevolution, and Reinforcement Learning (RL) algorithms, supported by various examples. All the implementations can be just-in-time compiled with Jax, facilitating efficient execution across multiple accelerators, including GPUs and TPUs. These implementations effectively demonstrate the framework’s flexibility and user-friendliness, easing experimentation for research purposes. Furthermore, the library is thoroughly documented and tested with 95% coverage.
