    • hasRouteSelectionNeighborsRatio

      public boolean hasRouteSelectionNeighborsRatio()
       Ratio in [0, 1] of non start/end nodes to consider as neighbors for the
 identification of routes spatially close to a non start/end seed node.

 In particular, given a non start/end seed node s served by route r, we say
 that a route r' is spatially close to the seed node s if there is at
 least one non start/end node s' among the neighbors of s, such that s' is
 served by r'.

 The neighbors_ratio is coupled with the corresponding min_neighbors and
 max_neighbors values, defining the minimum and maximum number of neighbor
 nodes considered for a given seed node:
 num_neighbors = min(max_neighbors,
 max(min_neighbors, neighbors_ratio * NUM_NON_START_END_NODES))

 Neighbors ratio, and minimum and maximum number of non start/end neighbor
 nodes for the identification of spatially close routes.
      optional double route_selection_neighbors_ratio = 4;
      Specified by:
      hasRouteSelectionNeighborsRatio in interface RuinRecreateParametersOrBuilder
      Returns:
      Whether the routeSelectionNeighborsRatio field is set.
