I don't think so, but http://trac.sagemath.org/sage_trac/ticket/237
probably pretty closely related, given the following quote from the
Motivation and History
I wrote ries after I was frustrated by services such as Plouffe's
Inverter and the Inverse Symbolic Calculator. In case you're
wondering, the things that frustrated me are described here. I had
also been getting occasional emails from members of the Cult of 137,
and like-minded people claiming formulae for such things as the area
of the Mandelbrot set. I thought it would be nice to be able to
demonstrate how easy it is to find a formula for any number.
ries was first created for Linux1, but is is easily ported to Mac OS
X, and nearly any OS with a C compiler. It uses only the standard C
math and stdio libraries. The source code is distributed under GPL
2.0. You can also get the manpage source. If you don't already have a
copy, you should also retrieve the GNU General Public License version
2.0, which defines the terms under which this source code is made
available to you, here.
I think this would be a really great tool for Sage, because currently
it's something where Maple is obviously ahead of us. I'm excited that
there is an open-source version of this - any word on the rep it has
in that symbolics community? Also note that it is apparently
currently GPL 2, not GPL 2+.
