See title. Maybe a recent change in the CP implementation that screwed the example?
-
Add module for objective functionals for primal-dual formulations of optimization problems.
Properties:
- convex conjugate
- proximal operator
- separable sum
- gradient
EDIT @kohr-h: gradient added
-
Add the first-order primal-dual algorithm developed by Chambolle and Pock for non-smooth convex problems.
-
The following code gives an `IndexError`:
``` python
>>> r2 = odl.Rn(2)
>>> prod_space = odl.ProductSpace(r2)
>>> prod_space[1:]
Traceback (most recent call last):

I initialized a structure, but it is obviously far from optimal. We need to find sensible categories for solvers, e.g.

Chambolle-Pock doesn't converge. The algo is quite sensitive to the value of theta (observe this in fluctuations of the primal energy curve, etc.). Why are we not using the original value (from the pa…
