Comment #8 on issue 1400 by smi...@gmail.com: make cse optionally not to
generate subexpressions that are only used once
http://code.google.com/p/sympy/issues/detail?id=1400
I think this is now fixed and should never return a symbol that is only
used once.

this. I think this is different, because an

Hi folks,
I have a straightforward, but tedious probability problem that I need to
expand symbolically. Sympy's set and interval material is close, but I
can't see how it would work in a multidimensional application. I've used
Sympy for some fairly intricate PDE problems, but never for this
Short answer here is, I think, no.
The short answer *should be* that sympy.stats should be able to handle all
of this for you at a level higher than sets. It currently errs on this sort
of question unfortunately. It wouldn't be hard to add though. The
infrastructure is there.
Sets handles this
Actually, we could give you a set of non-intersecting sets fairly easily.
Your problem can be written as follows
In [2]: s = Union(Interval(2, 5)*Interval(-oo, oo), Interval(-oo,
oo)*Interval(3, 8))
In [4]: 2.complement.complement
Out[4]:
(((-∞, 2) ∪ (5, ∞)) × [3, 8]) ∪ ([2, 5] × ((-∞, 3) ∪ (8,
I'm not strictly convinced that that will work for all complex cases. You
should double-check your first results.

So we were not accepted to Google Code-In this year. I want to thank to
everyone who helped out with the application and task creation. Google
only accepted ten mentoring organizations this year (as opposed to eighteen
from last year), so the competition was a little higher.

Hi Matthew,
Thank you very much for the examples, I'll play around with them and see if
I can cojole things into shape.

Hello. I'm new to SymPy.
I am trying to implement an algorithm in Python for merging Bezier
curves from this paper:
http://cg.cs.tsinghua.edu.cn/~shimin/pdf/cad%202001_merging.pdf and in
it (after spending quite some time in understanding the mathematics,
as I am actually a humanities scholar) I
This looks like a manifestation of this bug:
http://code.google.com/p/sympy/issues/detail?id=2663#c3. It's not clear why
it is happening or how to fix it without seeing your definition if QPointF.
