@Deprecated
public final class RuinRadialMultipleCenters
extends AbstractRuinStrategy

RuinStrategy that ruins the neighborhood of a randomly selected job. The size and the structure of the neighborhood is defined by the share of jobs to be removed and the distance between jobs (where distance not necessarily mean Euclidean distance but an arbitrary measure).

ruinRoutes

public Collection<Job> ruinRoutes(Collection<VehicleRoute> vehicleRoutes)

Deprecated.

Ruins the collection of vehicleRoutes, i.e. removes a share of jobs. First, it selects a job randomly. Second, it identifies its neighborhood. And finally, it removes the neighborhood plus the randomly selected job from the number of vehicleRoutes. All removed jobs are then returned as a collection.
