[jira] Created: (MATH-405) Inconsistent result from Levenberg-Marquardt

JIRA jira@apache.org
Inconsistent result from Levenberg-Marquardt
--------------------------------------------

                 Key: MATH-405
                 URL: https://issues.apache.org/jira/browse/MATH-405
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Dimitri Pourbaix
            Assignee: Dimitri Pourbaix
             Fix For: Nightly Builds


Levenberg-Marquardt (its method doOptimize) returns a VectorialPointValuePair.  However, the class holds the optimum point, the vector of the objective function, the cost and residuals.  The value returns by doOptimize does not always corresponds to the point which leads to the residuals and cost
