| -snes_linesearch_type <bt> | - bt,basic. Select line search type | |
| -snes_linesearch_order <3> | - 2, 3. Selects the order of the line search for bt | |
| -snes_linesearch_norms <true> | - Turns on/off computation of the norms for basic linesearch (SNESLineSearchSetComputeNorms()) | |
| -snes_linesearch_alpha <alpha> | - Sets alpha used in determining if reduction in function norm is sufficient | |
| -snes_linesearch_maxstep <maxstep> | - Sets the maximum stepsize the line search will use (if the 2-norm(y) > maxstep then scale y to be y = (maxstep/2-norm(y)) *y) | |
| -snes_linesearch_minlambda <minlambda> | - Sets the minimum lambda the line search will tolerate | |
| -snes_linesearch_monitor | - print information about progress of line searches | |
| -snes_linesearch_damping | - damping factor used for basic line search |
Notes: This is the default nonlinear solver in SNES
