Additional PETScTAOSolver methods

[Joshua Chen]

Particular interest is for using linearly constrained lagrangian method and interior point method. Can this be rethought to include more of petsc’s TAO capabilities?

[Prof Garth Wells]

What isn't accessible? You can access the underlying TAO object.

[Joshua Chen]

Well a lot of taotypes are missing in the std::map of Tao Methods. It may be the case that for example TAOLCL is available via settting PETScOptions though?

[Prof Garth Wells]

I would like to reduce (or even remove) the methods in the std::map - use the PETSc options system to get full control.

[Joshua Chen]

In this case, how are equality constraints set in an "OptimizationProblem" through the FEniCS interface?

[Prof Garth Wells]

We are not going to replicate the TAO/PETSc interface. You can access the underlying TAO object from the FEniCS wrapper and manipulate it as you wish.
