== Using OptaPlanner or Timefold
+OptaPlanner is an optimization library combining optimization algorithms with
constraint solving.
+For most of the last 10 years the library was developed under Red Hat's
guidance.
+In the last 12 months, the project and other related projects
+were donated to the https://www.apache.org/[ASF] as part of
https://kie.apache.org/[Apache KIE].
+More recently, the library was forked as [Timefold].
+
+We'll use Timefold, but the code in the examples remains the same for both
libraries.
+Just the Maven coordinate of the library changes along with the associated
class imports.
+At this stage, it isn't clear how the two projects will evolve over time.
+
+One of the claims of the Timefold project is that it has a lighter dependency
footprint.
+This can be confirmed by running the `printRuntimeClasspath` task in the
associated builds.
+Timefold has 20 dependant jars compared with OptaPlanner's 55 jars.
