Bugs in "BrentOptimizer"
------------------------
Key: MATH-395
URL: https://issues.apache.org/jira/browse/MATH-395
Project: Commons Math
Issue Type: Bug
Affects Versions: 2.1
Reporter: Gilles
Assignee: Gilles
I apologize for having provided a buggy implementation of Brent's optimization
algorithm (class "BrentOptimizer" in package "optimization.univariate").
The unit tests didn't show that there was something wrong, although (from the
"changes.xml" file) I discovered that, at the time, Luc had noticed something
weird in the implementation's behaviour.
Comparing with an implementation in Python, I could figure out the fixes. I'll
modify "BrentOptimizer" and add a test. I also propose to change the name of
the unit test class from "BrentMinimizerTest" to "BrentOptimizerTest".
