[petsc-users] help: (petsc-dev) + petsc4py acessing the tao optimizations solvers ?

[André Timótheo]

p.s. I am not quite sure of the need of petsc-dev. I Just read about the
inclusion of tao solvers in it and installed petsc-dev, cython and petsc4py
on my ubuntu 12.04.

Unfortunately petsc4py (and the old tao4py) documentation does not have
this type of python documented examples. After some correspondence in
petsc4py mailing list they suggested that I might find some help on
petsc-users mailing list.
