Package: optimix 0.2.0

optimix: A Unified Contract and Auto-Selector for Efficient Optimisers

Provides a single typed problem contract over a curated portfolio of efficient optimisers, with an automatic per-instance selector that picks the best optimiser for a given problem and returns it in an 'stats::optim()'-compatible result object. The base solver runs with no suggested packages installed; each additional engine, and an optional mixture-valued mapper from 'proxymix', is loaded lazily only when used.
