General framework for iterative algorithms
------------------------------------------
Key: MATH-655
URL: https://issues.apache.org/jira/browse/MATH-655
Project: Commons Math
Issue Type: New Feature
Affects Versions: 3.0
Reporter: Sébastien Brisard
Priority: Minor
Following the thread [Monitoring iterative
algorithms|http://mail-archives.apache.org/mod_mbox/commons-dev/201108.mbox/%3CCAGRH7HrgcgoBA=jcoKovjiQU=TjpQHnspBkOGNCu7oDdKk=k...@mail.gmail.com%3E],
here is a first attempt at defining a general enough framework for iterative
algorithms at large. At the moment, the classes provide support for
* maximum number of iterations
* events handling
** initialization event (prior to entering the main loop),
** iteration event (after completion of one iteration),
** termination event (after termination of the main loop).
These classes do not yet provide support for a stopping criterion.
Some points worth to note
* For the time being, the classes are part of the o.a.c.m.linear package.
* For the time being, {{IterativeAlgorithm.incrementIterationCount()}} throws a
{{TooManyEvaluationsException}}. If the proposed new feature is integrated into
CM, then a proper {{TooManyIterationsException}} should be created, from which
the former could derive.
