|-snes_linesearch_minlambda <minlambda>||- the minimum acceptable lambda|
|-snes_linesearch_maxstep <length>||- the algorithm insures that a step length is never longer than this value|
|-snes_linesearch_damping <damping>||- initial trial step length is scaled by this factor, default is 1.0|
|-snes_linesearch_max_it <max_it>||- the maximum number of secant steps performed.|
This method is the preferred line search for SNESQN and SNESNCG.
