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