In

@article{BruneKnepleySmithTu15,
  title   = {Composing Scalable Nonlinear Algebraic Solvers},
  author  = {Peter R. Brune and Matthew G. Knepley and Barry F. Smith and
Xuemin Tu},
  journal = {SIAM Review},
  volume  = {57},
  number  = {4},
  pages   = {535--565},
  note    = {\url{http://www.mcs.anl.gov/papers/P2010-0112.pdf}},
  url     = {http://www.mcs.anl.gov/papers/P2010-0112.pdf},
  doi     = {10.1137/130936725},
  year    = {2015},
  petsc_uses={KSP},
}

we mention them all and give citations. There is not a lot of predictive
theory.

  Thanks,

     Matt
