Re: [rules-users] [planner] Scheduling events with varying durations - corrupted score

A) Timeslots only work if they are fixed in start and end time, _before_ any planning entities are assigned to them. For example, in lesson planning, each timeslot is 50 minutes (for example). In conference planning, timeslots differ in length, but there start and end times are fixed: the keynote is from 10 till 11, the university talks are from 12 till 15, the conference talks are from 12 till 13, ... B) If that's not the case in your use case, you need to go a more difficult route, similar to a "vehicle routing" problem. The idea is that an Event is scheduled sequential after another Event (or each Event has an index). The score rules can use something like a custom insertLogical object EventAssignedStartAndStopTime (similar like how the nurse rostering score rules use insertLogical objects). This more difficult route is not yet supported by the construction heuristics, but I am working on that for planner 5.4. So you 'll need to write a custom SolverPhase to construction a solution (see *StartingSolutionInitializer classes), but you can still reuse the local search algorithms.
