Definition at line 252 of file RuinRecreateParameters.java.

◆ getRouteSelectionNeighborsRatio()

double com.google.ortools.constraintsolver.RuinRecreateParameters.getRouteSelectionNeighborsRatio ( )

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;

Returns: The routeSelectionNeighborsRatio.
