Luc Maisonobe commented on MATH-655:
------------------------------------
I think composition would be fine. Most probably, most immediate changes in ODE
would be limited to our own classes and not user classes. The changes in user
classes could be dealt with progressively if we deprecate an interface and set
up other interfaces.
We have to be aware that the continuous output and events handling features in
ODE are really very important. But I think the proposed API improves things and
suits our needs. I did not try to go all the way and check it on real code, but
I am confident it will be possible.

> 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.
