Debugging if a certain class in planning cloned is hard to do. It would be much easier if at solving start, after the TRACE logging logs the planning entities and...
Motivation: we know realize that the @PlanningSolution class itself is not boilerplate. But much of it's annotations are. Let's support this feature on quarkus too: ``` public @interface PlanningSolution {...
Currently it only shows the top 3 or so. For debugging purposes (User Experience), it's often handy to be able to show them all, or the top 20. Not all...
This pattern is common: ``` f.forEach(MyEntity) .groupBy(MyEntity::myGrouping, count()) .join(MinMaxRule, ... same myGrouping ...) ``` It's also **buggy**. If nothing is assigned to the grouping, the MinMaxRule isn't checked. This is...
For a case like this: ``` @PEntity class Vehicle { @PListVariable List visits; ... } ``` with 50k visits, the Construction Heuristic runs very long. For Shift to Employee assignments,...
Our docs have a full "advanced" CH config for a normal variable: ```` PHASE SORTED DECREASING_DIFFICULTY PHASE SORTED INCREASING_STRENGTH ```` https://docs.timefold.ai/timefold-solver/latest/optimization-algorithms/construction-heuristics#allocateEntityFromQueueConfiguration but it **lacks that for a list variable**. That...
Currently, a score is always calculated entirely (all-or-nothing). For example, when a move changes shift A to Beth, but Beth doesn't have the right skill for A, it will calculate...
