**Describe the bug** We have a `Stock` class which tracks the stock level of a `Product` per `Period`. The `quantity` of the `Stock` is a shadow variable of the `quantity`...
`ConstraintVerifier` should support `compareToGiven(Facts...).penalizesMore(String?)` Example usage: ```java constraintVerifier.verifyThat(MyConstraintProvider::fairnessConstraint) .given(Shift(Amy), Shift(Amy), Shift(Beth), Shift(Beth)) .compareToGiven(Shift(Amy), Shift(Beth), Shift(Beth), Shift(Beth)) .penalizesLess(); ``` _Originally posted by @Christopher-Chianelli in https://github.com/TimefoldAI/timefold-solver/pull/918#discussion_r1664306923_
Are there plans to add Guided Local Search to Timefold in the near or not-so-near future?
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...
**Describe the bug** When running Timefold Solver with a very short termination (`spent-limit=1s`, `unimproved-spent-limit=1s`), the following behaviour occurs - please notice the CH step (12) that selects a move changing...
Benchmarked to be a statistically significant improvement for joining operations.
The current recommended fit API serves the purpose of finding the best possible spot for a newly created (not yet assigned) entity. Once the spot is found, it can explain...

Goal: to have a Move interface in the public API which can be used to build both generic and custom moves.
