Direct Known Subclasses:

AbstractKMeans, DependencyDerivator

public abstract class AbstractPrimitiveDistanceBasedAlgorithm<O,D extends Distance<?>,R extends Result>
extends AbstractAlgorithm<R>

Provides an abstract algorithm already setting the distance function. This class only allows distances that are defined on arbitrary objects, not only database objects!
