Gilles commented on MATH-442:
-----------------------------
So, as I said, it was perhaps a bad choice of the package names. From a usage
perspective it is more useful to make categories based on the properties of the
objective function rather than on the heart of the algorithms.
I think that the interfaces should be based on familiarity (e.g. identically
named methods) and ease of use, and that implementations similarities should be
shared through inheritance.
What do you propose instead of the current {{direct}} and {{general}} package
names?

> Key: MATH-442
> URL: https://issues.apache.org/jira/browse/MATH-442
> Project: Commons Math
> Issue Type: New Feature
> Affects Versions: 3.0
> Reporter: Dr. Dietmar Wolz
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> Recently I implemented the optimization algorithm CMA-ES based on
> org.apache.commons.math.linear and used it for the GTOC5 global trajectory
> optimization contest http://gtoc5.math.msu.su/. It implements the
> MultivariateRealOptimizer interface and would nicely fit into the
> org.apache.commons.math.optimization package. The original author of CMA-ES
> (Nikolaus Hansen) volunteered to support me (proof-reading + testing) in the
> creation of a CMA-ES contribution for commons.math.
> The CMA evolution strategy http://www.lri.fr/~hansen/cmaesintro.html is a
> very powerful algorithm for difficult non-linear non-convex optimization
> problems in continuous domain. See http://www.lri.fr/~hansen/cec2005.html for
> a comparison chart. If there is interest I will create a patch including the
> proposed Implementation for evaluation. It seems we would need an additional
> sub-package - org.apache.commons.math.optimization.evolutionary.
