-snes_linesearch_type <bt> | - bt,basic. Select line search type Many br | |
-snes_linesearch_order <3> | - 2, 3. Selects the order of the line search for bt Many br | |
-snes_linesearch_norms <true> | - Turns on/off computation of the norms for basic linesearch Many br | |
-snes_linesearch_alpha <alpha> | - Sets alpha used in determining if reduction in function norm is sufficient Many br | |
-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) Many br | |
