A New Major Version of PHYSBO!

Major Changes

PHYSBO v3 introduces three major changes:

Cython code moved to external package: Code written with Cython has been moved to the external package physbo-core-cython [#77]
- This simplifies the installation process of PHYSBO, particularly on Windows
- The performance (speed) of PHYSBO is slightly reduced compared to PHYSBO v2
- Users can achieve the original performance by installing the physbo-core-cython package
Class names capitalized according to PEP8: Many class names have been capitalized to follow PEP8 (Python code style guide) [#73]
- For example, the physbo.search.discrete.policy class becomes physbo.search.discrete.Policy
- The old names are marked as deprecated, so users can still use them with warnings
NumPy2 support: Full support for NumPy2 has been added [#70]
- While PHYSBO v2 code worked with NumPy2, the required NumPy version was capped

New permutation importance (PI) calculation methods [#72]
- PI helps identify which features (parameters) are most influential for the objective functions
New policy classes: physbo.search.range.Policy and range_multi.Policy [#76]
- These policies perform Bayesian optimization directly in continuous parameter spaces
- Since optimizing the acquisition function in continuous space is more challenging than in discrete space, we recommend using discrete optimization when possible

Tutorial notebooks: Jupyter notebooks used as tutorials have been uploaded to ISSP datarepo [#75]
- See the data/tutorial directory
