What I'll do, is copy/paste all methods from IterativeAlgorithm into
IterativeLinearSolver, [...]

That's what I understood; the monitoring methods will become part of the API of
{{IterativeLinearSolver}} and it will be "difficult" to remove them (in 3.x).
I've no precise idea about how a general monitoring framework should be
designed but my impression is that a math algorithm class should be (as much as
possible) independent of it. We should probably explore all the various
suggestions that came up during the discussion on the ML before trying anything
lest we want to reinvent the wheel... ;)
> 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
> Labels: algorithm, events
> Attachments: iterative-algorithm.zip

>
> 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.
