parmoo/parmoo: v0.2.0

:Date: Feb 2, 2023

Official release corresponding to accepted JOSS article.

• Added support for a wider variety of design variables (including integer types), as well as support for "custom" design variables that use user-provided custom embedders/extractors Documentation on design variables has been expanded accordingly. Although design variables are still specified through dicts not classes, this addresses and therefore closes the primary issue raised in parmoo/parmoo#28
• Updated extras/libe.py corresponding to interface changes made in libEnsemble Release 0.8.0. This also addresses the issues on MacOS, referenced in parmoo/parmoo#34
• Added a post-run visualization library and corresponding documentation, closing issue parmoo/parmoo#27
• Allow solvers to start from an initial point that is infeasible, so that problems with relaxable constraints and a very small feasible set can still be solved
• Various style changes and additional usage environments requested by JOSS reviewers openjournals/joss-reviews#4468 including parmoo/parmoo#32
• Added support for multistarting optimization solvers when solving surrogate problems. This is particularly important for the global GaussRBF surrogate
• Fixed an issue in how model improvement points are calculated, as implemented in the surrogate.improve method for each GaussRBF variation in surrogates/gaussian_proc.py, which was created when adding support for custom design variables
• The default design tolerance for continuous variables now depends upon the value of ub - lb

Note:

• Dropped support for Python 3.6, due to changes to GitHub Actions documented on actions/setup-python#544

Known issues:

• The visualization library uses advanced plotly/dash features, which may not support the chrome browser, as described in parmoo/parmoo#37
