I'm thinking about implementing a formula guesser for C-finite integer
sequences.
There is now a working implementation
at https://github.com/sympy/sympy/pull/8811
and I want to resolve here two questions posed by Sergey.
Initially, I used the name guess to do 1. finding of linear
Hi,
I'm trying to use sympy KanesMethod to model biological assemblies (i.e.
the mitotic spindle).
Molecular motors in biology follow linear force velocity relationships,
such that F = F_max(1 -ld/V_max) where ld is the relative speed of the
two points on which the force is applied
To me, the relevant concept seems to be software coupling, as railed
against by structured programming gurus in the 1970s and 80s.
Having imports which know exactly where a symbol is defined, increase the
knowledge that one part of our code has of other parts.
Coupling is often unavoidable,

Coupling is logical interdependency.
An import already establishes that dependency.

Bastian,
Maybe https://www.openhub.net/ has both projects. It has sympy and a bunch
of stats.
Feel free to improve the wiki page on the sympy repository as it will
likely help others too.

The link that Jason sent provides data for b), c), d). Few more comments:
a) I think that's comparable, if there is anything that Maxima can do
and SymPy can't, please let us know. SymPy might have more features in
specific areas.
b, c) I think sympy has more developers and the community is more
Some notes:
- Since you specified your kinematic relations as u = q', then you should
set your velocities with u instead of q, for example: p1.set_vel(N, u1d * N.
x)
- I doubt that you need to specify any velocity constraints and thus you
will not have any dependent speeds. You've defined ell as
I meant: p1.set_vel(N, u1 * N.x)

In last year GSoC there was a project on improving the geometry module. How
much of that was implemented?. Is there any project for geometry module in
this year GSoC.
cheers!

herself, and
so needs a command just for 1). All in all there are three possibilities:
