      true if the time bounds of the activity intersect with the time bounds of the cluster

    • resolve

      public Map<A,​Placement<A>> resolve​(Predicate<A> filter)

      Parameters:
      filter - a filter used to ignore some of the activities
      Returns:
      a map structure containing the placement for each activity within the cluster
