Timefold Solver (OptaPlanner)

Replacing the former OptaPlanner an open source (Apache 2.0 license) Java library, is Timefold Solver, used to optimize business resource planning, an AI constraint solver primarily used to optimize employee shift rostering and similar use cases. Timefold Solver is free and open source, as OptaPlanner was. Timefold also offers Solver Enterprise, a commercial offering.
