Gilles Sadowski bbfe7e4ea5 MATH-1531: Avoid spurious exception. 
In the provided use-case, computation resulted in a value slightly above 1,
thus throwing an exception (invalid probability).
Workaround replaces the value by 1 when it is up to one ULP away.

Closes #128.

Gilles Sadowski ab33121f7b Use "sample" functionality from "ListSampler". 
Change should improve performance by
 * extracting the number of required items (instead of shuffling the whole list),
 * converting the "Collection" to a "List" once.

Gilles aef8f5272d Reduce visibility of method that is meant to be used internally only. 
Note: Since "Cluster" is mutable, the "center" stored in "CentroidCluster"
may become inconsistent with the actual contents of the cluster.
See MATH-1524.
 2020-03-13 04:07:48 +01:00
Gilles cd0988f9bf Method "centroid()" is available for any "Cluster" instance (userguide).
