◆ RouteSelectionNeighborsRatio

double Google.OrTools.ConstraintSolver.RuinRecreateParameters.RouteSelectionNeighborsRatio
getset

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.
