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 > ------------------------------------------------- > > 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 > Fix For: 3.0 > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
