Did the build work? (Maybe I need to wait 7 more hours for an answer.)
I use Ubuntu 11.10, 64 bit, and I have a core i7-2600. I think building
Sage using many processes usually takes me about 2 hours + 15 minutes,
where the 2 hours is all ATLAS, and the 15 minutes is everything else. I'm
building
Hi kcrisman,
Thanks for answering. Yes, I did sage -b which worked perfectly.
I tried the procedure on two different machines (one on Mac OS 10.6
and the other on Mac OS 10.7), but I got the same error message on
both.
regards,
yann

FYI, SAGE_PARALLEL_SPKG_BUILD is deprecated since
http://trac.sagemath.org/sage_trac/ticket/11959 was merged (4.8.alpha0).
Sage currently builds SPKGs in parallel by default. To turn this off you
would need to edit $SAGE_ROOT/spkg/parallel_make.cfg .

Heloo Yann !!!
Hmmm, like Karl said, what your error tells us is that something went wrong
when CPLEX was installed.
Sage detects that you want to install CPLEX by checking that there is a
file named libcplex.a in SAGE_ROOT/local/lib/ and a file cplex.h in
SAGE_ROOT/local/include/. It
Oh and by the way, I would be very glad to know what you are doing with
Sage and with LP ! Just being curious :-)

Hi all
Thanks for your support! And yes, the build worked.
Tried Dima's suggestions to cut down compute time
(a) SAGE_ATLAS_ARCH=CoreI7,SSE3,SSE2,SSE1... unfortunately rejected??
(b) Tried Loading Ubuntu Atlas package. Couldnt find one.
(c) Tried Installation manual trick for Ubuntu installs.

I think that needs to be be SAGE_ATLAS_ARCH=Corei7,SSE3,SSE2,SSE1
(note the capitalization of the i).
Return the maximal distance from the center to a vertex.
Shouldn't this be translation invariant? Doesn't seem like any of
these are answers right.
sage: sq=polytopes.n_cube(2)
sage: sq.vertices()
[[1, 1], [-1, 1], [1, -1], [-1, -1]]
sage: sq.radius()
2*sqrt(2)
sage:
These would make great examples for the sage wiki!

That looks obviously broken to me. I'll write a patch.

hi,
I'm glad to inform you about new Python solver for multiobjective
optimization (MOP:
Some changes committed to solver interalg (http://openopt.org/
interalg) made it capable of handling global nonlinear constrained
multiobjective problem (MOP), see the page http://openopt.org/MOP for
more

Could 'center' here mean 'origin'? It's not obviously unreasonable to
assume that a polyhedron is defined so that they coincide.

Ivan and Karl,
Thanks for pointing out Huss and Marik's sws2tex! That's mostly what I
want. As discussed on ask.sagemath.org, there are some problems:
with solutions: turning off syntax highlighting, turning off the attach
file, saving the TeX file
no (yet!) solutions: aligns of equations are
Seems unlikely to me. The output does not match this theory either.

Salut Nathann !
Thanks for your answer.
I touched the files as you asked, and here is the result below. The
sage -b command went much faster than when I first installed CPLEX.
By the way, I'm using MILP to solve machine learning problems with
some combinatorial aspects. For example, given a

New versions of CPLEX need one more symbolic link. See

Arggg !! I had totally forgotten this ticket !
I just updated the patch :-)
Yann, could you add this link Jason mentionned, then
Hello,
Unfortunately, I had already made the symbolic link to cpxconst.h

Hiya - is there something new in parameter_plot?
I was using parameter_plot for both 2d and 3d plots and now something
is not working.
Thanks, Linda

Can you give an example of what worked before, but is not working now?

Hi Nathan,
Yes, I checked local/include and local/lib. CPLEX runs fine also as a
64 bit standalone.
I recompiled everything with ./sage -ba, and now
MixedIntegerLinearProgram(solver=CPLEX) triggers a new error
message
I put the log below:
