So, can I use the petsc options database file with libmesh? I know about nocedal and wright, but I was unable to find any reference on the petsc website to the exact algorithm that they were using. They have provided them for the snes vi algorithms and that was very useful, and that is why I wanted to know.

For line search (and optimization-based methods in general), I really like Nocedal and Wright http://www.amazon.com/Numerical-Optimization-Operations-Financial-Engineering/dp/0387303030/ref=sr_1_1?ie=UTF8&qid=1345560009&sr=8-1&keywords=numerical+optimization I also would like to know how to set petsc options from within libmesh code. You should be able to set them at the command line. If not, please post an example since they should work.
