   FWIW, OptaPlanner also works on Kotlin and Scala, not just Java. There is a 100% Kotlin variant of the quarkus-school-timetabling quickstart is also the optaplanner-quickstarts repo - and there's a video of that. Some users have been s

   No need to use XML any more. Take a look at the school-timetabling quickstart video, guide and/or code :)

   For decision tables, definitly look at Kogito and Drools-DMN as alternatives. To declare incremental constraints in OptaPlanner, take a look at ConstraintStreams if you want to avoid learning DRL: https://www.optaplanner.org&#x

   Thank for the analysis. You really get how OptaPlanner is not your father's solver! It is a team effort. Credit is due the rest of the team too (Lukas, Radovan, Jiri, Christopher, Julian, Karina, Duncan, Michal, Anna, Emily, Michael, M

   Thanks for the kind words. We've working hard to reduce the complexity and will continue to do so. For example: - ConstraintsStreams (instead of DRL) to declare incremental constraints easily in plain Java (or another JVM language). No

   In OptaPlanner you can grab the Vehicle Routing web application (called optaweb-vehicle-routing) and add any custom constraints that are specific to your use case such as emergency vehicles: https://www.optaplanner.org/learn

   OptaPlanner (Apache license, 100% Java) is a constraint solver. MiniZinc (MPL, C++) is a modeling language for other constraint solvers. Both are used for similar use cases - Vehicle Routing Problem, employee rostering, task assignment, ...

    I used this TSP solver configuration: https://github.com/droolsjbpm/optaplanner/blob/master/optapl... but with incremental Java calculation instead of scoreDrl, to speed things up.

    Drools planner is lightweight: use simple score calculation and you need only about 5 jars (planner, xstream and apache commons jars)
