Dr. Dietmar Wolz commented on MATH-442:
---------------------------------------

An initial version of the patch is now reviewed by Nikolaus Hansen and will 
hopefully soon be attached.I followed all the hints given in the mailing list.

> CMA evolution strategy is missing in optimization

> 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.
