-snes_ls [cubic,quadratic,basic,basicnonorms] | - Selects line search | |
-snes_ls_alpha <alpha> | - Sets alpha | |
-snes_ls_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_ls_minlambda <minlambda> | - Sets the minimum lambda the line search will use minlambda / max_i ( y[i]/x[i] ) |
