The new major release of Relexi comes with a substantial improvements in terms of ease-of-use and code quality and adds several new features. The most important ones include:

Features:

• Implemented beta distribution for PPO policy to accelerate training. Selection of normal or beta distribution is done via the config.yaml file.

• Cleaned commandline interface of Relexi main script relexi.py
• Relexi main script is installed with package installation to path as relexi and thus provides a direct CLI tool.

Code Quality:

• Published release as Python package on PyPI.
• Restructured folder tree to comply with Python packaging standards.
• Modularized functionality into separate subpackages.
• Adapted codebase to conform to PEP8 standard.
• Automated documentation of public API using pdoc, which is published via GitHub pages.
• Implemented UnitTests via pytest and automated integration testing via Gitlab CI/CD.
• Added CFF conform citation file.
• Updated references and citations.
• More robust validation of user input and overall increased robustness as well as more helpful warning and error messages for users.

Dependencies:

• Bump SmartSim and SmartRedis dependencies to up-to-date versions.
• Fixed issues and now support for OpenMPI 5.X
• Correct and automated handling of Python dependencies via pip and pyproject.toml file.
• Streamlined and updated installation process
