Gilles commented on MATH-855:
-----------------------------

That was not it yet; further improvement committed in revision 1382070, together with a Javadoc
update explaining some change wrt the original version of the algorithm.

> {{BrentOptimizer}} (package "o.a.c.m.optimization.univariate") does not check that the
point it is going to return is indeed the best one it has encountered. Indeed, the last evaluated
point might be slightly worse than the one before last.
