This workshop may be of interest to those who are working on features
related to mathematical optimization in Sage.
"COIN fORgery: Developing Open Source Tools for Operations Research" will
be held at the IMA (Institute for Mathematics and its Applications,
University of Minnesota) October 15
I was benchmarking some code (in particular the density() method of
matrices) and noticed code of the form
if not x.is_zero():
however, that's a lot slower than doing just
if x:
So, this makes me wonder: what is the reason for the is_zero() method?
Are there classes where "x.is_zero()" is

It looks very obscure and is certainly nothing that could be executed in

Indeed it was not very clear... Aishen was actually referring to the

Fixed: I had to ensure that languages variables (LANGUAGES, LC_ALL, LANG)
are well set. This was somehow done by default with previous versions of
the system.
Best,
