Package elki.clustering.optics
OPTICS family of clustering algorithms.
Note that some OPTICS based algorithms (HiCO, DiSH) are in the subspace and correlation packages, which better describes their use case.

Interface Summary Interface Description GeneralizedOPTICS A trivial generalization of OPTICS that is not restricted to numerical distances, and serves as a base for several other algorithms (HiCO, HiSC).OPTICSTypeAlgorithm Interface for OPTICS type algorithms, that can be analyzed by OPTICS Xi etc.
