Re: [bug #18019] Gridsearch appears not to be working when upper/lower bounds are set -- April 12, 2011 - 08:51

Hi,

Is there any reason this bug report has been made private?  The data
is so truncated, there's nothing much anyone can do with it.  The
privacy tag is usually reserved for security issues whereby it needs
to be kept private until a fix is found and released.  Then the bug
can be made public.  I'm looking into this now, but I'm not exactly
sure what is happening.  Is it ok if I include this data, or part of
it, into the relax test suite?  This will significantly help in the
debugging and will make sure this bug never returns!

Cheers,

Edward
