Subject [jira] [Commented] (MATH-1057) BOBYQAOptimizerTest has two failing tests
Date Sun, 03 Nov 2013 21:30:18 GMT

    [ https://issues.apache.org/jira/browse/MATH-1057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812498#comment-13812498
] 

Thomas Neidhart commented on MATH-1057:
---------------------------------------

Ah ok, now I get the same error, strange that I did not see it before.
In this case I think it would be fine to change the epsilon to 1e-7 but I would like to understand
why we get different results for jdk 1.5 and 1.7 here.

> I tried on Mac OS X and Linux and see the same, so don't think it is an environment issue.
I'll see if a little digging can uncover the issue from a recent commit.
