Is it possible to select a pillar move based on problem facts in timefold?

Is it possible to select entities of a PillarMove based on other properties of the entity than PlanningVariables. For example my Entity has a PlanningVariable startTime and a type that is a ProblemFact. I want so select a pillar based on the startTime and all Entities that have the same value in their type property. Is that possible? I can't see that feature in the docs https://timefold.ai/docs/timefold-solver/latest/move-and-neighborhood-selection/move-and-neighborhood-selection.html#pillarMoveSelectors but I think its very essential. Is the only way to implement a custom move?

Solution

  • I can not think of a way of doing that.

    You could perhaps write your own custom move that would be inspired by our pillar move. But it is definitely not easy and it takes you outside of the public API, so it carries risks.
