[Trilinos-Users] Using NOX with Broyden method

I am trying to setup a nonlinear finite element mechanics solver using
QuasiNewton approach. The examples in NOX package and Didasko show how to
setup using Newton method. Can someone give an example on how to use the
Quasi-Newton/Broyden method?

Also, I am not sure which of these two options implements the limited memory
BFGS method by Nocedal. A little explanation on this will be greatly
appreciated. I have taken a basic graduate level course in Optimization, and
I understand the BFGS Quasi Newton method, but not the L-BFGS.
