-----------------------------------------
Summary: ConvergenceChecker should implement OptimizationData
Key: MATH-1658
URL: https://issues.apache.org/jira/browse/MATH-1658
Project: Commons Math
Issue Type: Improvement
Components: legacy
Affects Versions: 4.0-beta1
Reporter: François Laferrière
It is a bit peculiar that with BaseOptimizer, ConvergenceChecker can be passed
only in constructor.
It should be possible to change ConvergenceChecker at any other time.
Further it is a bit strange that the constructor do not accept other
OptimizationData.
In my use cases, I need to create an optimizer once with complex
OptimizationData and reuse it many time with very few changes (including
changing the ConvergenceChecker).
So, I suggest that
* ConvergenceChecker implements OptimizationData.
* protected BaseOptimizer(ConvergenceChecker<PAIR> checker) is replaced by
protected BaseOptimizer(OptimizationData... optData)
Doing so is compatible with existing code and provide much more flexibility.
