    • getDemandsList

      java.util.List<java.lang.Integer> getDemandsList()
       Experimental. The demands for each node, and the maximum capacity for each
 route. Note that this is currently only used for the LP relaxation and one
 need to add the corresponding constraint to enforce this outside of the LP.
 TODO(user): Ideally, we should be able to extract any dimension like these
 (i.e. capacity, route_length, etc..) automatically from the encoding. The
 classical way to encode that is to have "current_capacity" variables along
 the route and linear equations of the form:
   arc_literal => (current_capacity_tail + demand <= current_capacity_head)
      repeated int32 demands = 4;
      Returns:
      A list containing the demands.
