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

[André Timótheo]

 I read about the merger of the TAO solvers on the PETSC-DEV.

    How can I use the TAO's constrainded optimization solver on
the PETSC-DEV (via petsc4py)?

    Can you show me some simple python script to deal with classical linear
constrainded optimization problems like:

        minimize sum(x) subject to x >= 0 and Ax = b

    Thanks for your time.
