Subject [jira] [Commented] (MATH-1103) Convergence Checker Fixes
Date Thu, 27 Feb 2014 15:17:22 GMT

    [ https://issues.apache.org/jira/browse/MATH-1103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13914633#comment-13914633
] 

Gilles commented on MATH-1103:
------------------------------

bq. [...] is this OK for you?

I don't think so.
The concern I state is that the implementation of the optimization algorithm should not have
to figure out whether a copy must be made or not.
The default implementation of the "LeastSquareProblem" (i.e. "LocalLeastSquaresProblem" in
"LeastSquaresFactory") should use a "LeastSquareProblem.Evaluation" that makes a defensive
copy.
