-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.
