Hi,
I probably found an error in optimize.fmin_tnc. I was not able to supply an 
upper bound. If, e.g. I set the bounds to [-1,.1] I get:

tnc: Version 1.2, (c) 2002-2003, Jean-Sebastien Roy (js at jeannot.org)
tnc: RCS ID: @(#) $Jeannot: tnc.c,v 1.201 2004/04/02 22:36:25 js Exp $
tnc: All lower bounds are equal to the upper bounds
[-0.10000000000000001]

It only works when setting the upper bound to None.

scipy.__version__ is 0.3.2_288.4353

Regards, Christian
