DBSCAN* [6] [7] is a variation that treats border points as noise, and this way achieves a fully deterministic result as well as a more consistent statistical interpretation of density-connected components. The quality of DBSCAN depends on the distance measure used in the function regionQuery(P,ε).
The R package "dbscan" includes a C++ implementation of OPTICS (with both traditional dbscan-like and ξ cluster extraction) using a k-d tree for index acceleration for Euclidean distance only. Python implementations of OPTICS are available in the PyClustering library and in scikit-learn. HDBSCAN* is available in the hdbscan library.
A call of SetOfPoints.regionQuery(Point, Eps) returns the Eps-Neighborhood of Point in SetOfPoints as a list of points. In Neighbourhood (graph_theory) , it is stated: The neighbourhood described above does not include v itself, and is more specifically the open neighbourhood of v; it is also possible to define a neighbourhood in which v itself ...
scikit-learn (formerly scikits.learn and also known as sklearn) is a free and open-source machine learning library for the Python programming language. [3] It features various classification, regression and clustering algorithms including support-vector machines, random forests, gradient boosting, k-means and DBSCAN, and is designed to interoperate with the Python numerical and scientific ...

In Mac OS X 10.2, the internal codename "Jaguar" was used as a public name, and, for subsequent Mac OS X releases, big cat names were used as public names through until OS X 10.8 "Mountain Lion", and wine names were used as internal codenames through until OS X 10.10 "Syrah".
