Well I tried
v = iter(Permutations(range(n)))
and the code compiled fine - but still ran slow. To test the Petersen
graph (10 vertices), the compiled code took a wall time of 524.23 s,
and the uncompiled code, using
v=(p for p in Permutations(range(n)))
took a wall time of 492.22 s. The
OK. Let me try to be precise. The information I gave in my post was
not correct.
I have installed
sage-3.2.2-ubuntu32bit-intel-i686-Linux
and I receive the error message ... ILLEGAL INSTRUCTION ... pni but
however this version seems to be running well.
In order to try the next version I have
Hi everyone,
I run into a very strange problem, that looks like critical to me.
Basically, I plot two functions that I know must be tangent at a given
point, and they are not.
First, the code:
x,y=var('x,y')
utility=y*x^2
budget = 24-x
cp=contour_plot(utility,(x,0,24),(y,
I don't know anything about your economics problem but when I typed
cp=contour_plot(utility,(x,0,24),(y,
0,24),fill=False,cmap='cool',contours=(100,1000,2048,2700,3500),plot_points=200)
instead, I definitely got a different plot. Can you try that (or even
with a higher value)
and see if it is

David, William,
yes, by increasing plot_points it goes as it should. Thanks, and I
should have thought of it!
I second the idea of increaisng the default plot-points, at least to
100. On my not so recent intel duo it took less than a second with
200.
Thanks,

It looks like the reference manual needs to be updated. And you
pointing this out makes me rethink whether we should set some defaults
to make it easier to get the list out. But on the current version, to
get the list that you want you need to actually pull it from a
GraphQuery. The code looks

Dear Support,
I don't believe that turning a notebook worksheet into a pdf is
implemented (and thanks to Dan D. for SageTeX, which unfortunately I
haven't been able to use properly yet, and Rob B. for his interesting
experiments the other way). And that's fine, though it would be great
