> Key: MATH-563
> URL: https://issues.apache.org/jira/browse/MATH-563
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 2.2
> Reporter: Luc Maisonobe
> Assignee: Luc Maisonobe
> Priority: Trivial
> Fix For: 3.0
>
>
> There is a limitation of the current implementation of ODE integrators with
> adaptive step size. For now, the tolerances that are used to adjust the step
> size are specified only at construction time and cannot be changed afterwards.
> However, these tolerances are highly problem-dependent and in fact the
> dimension
> of the problem (which is related to the dimension of the vectorial version of
> the tolerances) is specified only at integration time, not at construction
> time.
> So it would be interesting to add at the top-level hierarchy (abstract class
> AdaptiveStepsizeIntegrator) a few setters to allow users to change these
> tolerances after the integrator has been built. It seems the integrators by
> themselves were not documented as immutable (I first thought they were), so
> this
> change is probably harmless.
> There was a discussion on the developers mailing list about this feature
> here: http://markmail.org/thread/djrjpm5pwcgg3ev4
