Nonlinear CG

Dear ITL-devel,
I'm glad I finally found ITL. It looks like it could be the Right Way to
solve a bunch of problems that various closed-source Fortran libraries have
attempted.

I am interested in solving large nonlinear minimization problems in
parallel. Presently we are experimenting with several CG solvers. The work,
but all of them want to see the state vector as a single contiguous array of
doubles. The ITL example using PETSc in parallel makes me think there are
interesting possibilities for large nonlinear problems as well.

The ITL distribution includes two nonlinear examples, but all of the solvers
appear to be linear. Has anyone extended ITL to do nonlinear minimization?

Again, great work.

Thanks,
   Ben FrantzDale
