In this release, we have focused a lot on the service module and accompanying documentation. But we have also fixed several important bugs and if you look very closely, you will find out that Neighborhoods-based custom moves now select elements more fairly, leading to a much less biased exploration of the search space.

Timefold Solver Community Edition is an open source project, and you are more than welcome to contribute as well! For more, see Contributing.

Timefold also offers commercial editions of the solver, which include additional features such as explainability, the ability to scale out to the biggest datasets, and enterprise-grade support. Find out more about the different editions.

How to use Timefold Solver

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

With Maven or Gradle, add the ai.timefold.solver : timefold-solver-core : 2.6.0 dependency in your pom.xml to get started.

You can also import the Timefold Solver Bom (ai.timefold.solver : timefold-solver-bom : 2.6.0) to avoid duplicating version numbers when adding other Timefold Solver dependencies later on.
