...and their hierarchy in a modular fashion – and has helped us in practical optimization problems already. It's fully auto-differentiable, and can be used as a composite objective with #botorch, which gives a big boost in optimization efficiency (check the paper for systematic benchmarks).

In the lab, we often face multi-objective problems, where objectives come as preferences over both the outcomes of an experiment (e.g. maximize the yield of a reaction) and experiment inputs (e.g. minimize the load of an expensive catalyst). BoTier helps you to express these preferences ...
