Subject [jira] [Commented] (MATH-1137) BOBYQA incorrect indexing
Date Tue, 15 Jul 2014 11:09:04 GMT

    [ https://issues.apache.org/jira/browse/MATH-1137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14061944#comment-14061944
] 

Gilles commented on MATH-1137:
------------------------------

bq. Nothing ever crashed, and I don't even know whether that bit of code is ever exercised,
but I will take up the challenge and see if I can make some tests with difficult functions
(e.g. Rosenbrook).

Just to make sure that we mean the same thing: By "crash", I mean that you should use a _modified_
version of CM, where the "throw" statement is not commented out in that block. If a code code
raises this exception, we can use it to further examine the behaviour of the block (by commenting
out the "throw" and fiddling with the parameters).

bq. the rescue code, which seems to not be there in the apache java version (probably a good
thing).

The "rescue" method was removed in revision 1158448. There was a discussion about this on
the MATH-621 page.


bq. How do I post to the "dev" ML?

See this page:
http://commons.apache.org/proper/commons-math/mail-lists.html

You should subscribe to the "dev" ML.
Then when you post, please add a "\[Math\]" prefix to the subject line (because the ML is
shared for all "Apache Commons" projects).
