- * A {@code StreamOverflowException} indicates that the internal state of the algorithm has overflown.
- * <p>
- * The exception may occur when the amount of items feeded to a random sampling algorithm exceeds the maximum allowed or
- * when the internal state has overflown in a way that would otherwise cause the algorithm to behave inconsistently.
+ * A {@code StreamOverflowException} indicates that the internal state of the algorithm has reached a situation where
+ * the precision has degraded into a non-recurrent state that would prevent the algorithm from behaving consistently.
