+integrates the result to find a clustering that gives the best stability over
+epsilon.  This allows HDBSCAN to find clusters of varying densities (unlike
+DBSCAN), and be more robust to parameter selection.  HDBSCAN is ideal for
+exploratory data analysis; it's a fast and robust algorithm that you can trust
+to return meaningful clusters (if there are any).")
