How to use Timefold Solver

To see Timefold Solver in action, check out the quickstarts.

With Maven or Gradle, just add the ai.timefold.solver : timefold-solver-core : 1.2.0 dependency to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 1.2.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
