When all next moves are not doable, optaplanner get stuck in step and if termination is not based on time, it cycles forever

    Description

      Consider TSP with one domicile and one entity. CH builds best solution and then local search is performed.

      Say that local search termination is configured like this:

      <termination>
      <stepCountLimit>1</stepCountLimit>
      </termination>

      obviously, there is no move what planner could do, but that is a problem. If planner is in state, when there is no way out, it will stuck forever and nothing can terminate it except time termination.

          is related to

          Bug - A problem that impairs or prevents the functions of the product. PLANNER-1738 If an entity's the value range is empty or a single element, it should set it and make it syntetically immovable

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          relates to

          Bug - A problem that impairs or prevents the functions of the product. PLANNER-241 If all entities are immovable (or there are no entities), the solver should simply do nothing. It should not log bailing out warnings.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
