Subject [jira] [Created] (MATH-879) "CMAESOptimizer" silently changes invalid input
Date Thu, 11 Oct 2012 12:35:03 GMT
Gilles created MATH-879:

             Summary: "CMAESOptimizer" silently changes invalid input
                 Key: MATH-879
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.0
            Reporter: Gilles
            Assignee: Gilles
            Priority: Trivial
             Fix For: 3.1

The "lambda" input parameter must be strictly positive. But when it's not the case, an undocumented
default is used (cf. line 526).
When a precondition is not satisfied, the code must throw an exception.
Instead of the code unknowingly changing the input, it is rather the documentation that should
suggest a good default.

This change would allow to make "lambda" a constant (final) field.
