Chapter 2. Red Hat Build of OptaPlanner 8.29 new features

OptaPlanner now includes support for the planning list variable. A planning list variable can contain multiple planning values. You can use it as an alternative to modeling planning problems that were previously modeled using the chained planning variable.

Use the planning list variable or the chained planning variable with problems where the goal is to distribute multiple workload elements between limited resources in a specific order.

For example, with the vehicle routing problem, vehicles represent the limited resource and customers represent the workload elements. The chained planning variable defines a recursive data structure, in which customers form chains ending with vehicles. On the other hand, the planning list variable provides a more intuitive model where each vehicle contains a list of customers that the vehicle goes to.

Use the new @PlaningListVariable annotation to define a planning list variable.

The following examples are included with this release:

The Employee Rostering reference implementation has been replaced with the Employee Rostering quickstart.
