-snes_ls [cubic,quadratic,basic,basicnonorms] | - Selects line search | |
-snes_ls_alpha <alpha> | - Sets alpha | |
-snes_ls_maxstep <max> | - Sets maxstep | |
-snes_ls_steptol <steptol> | - Sets steptol, this is the minimum step size that the line search code will accept; min p[i]/x[i] < steptol. The -snes_stol <stol> is the minimum step length the default convergence test will use and is based on 2-norm(p) < stol*2-norm(x) |
Notes: This is the default nonlinear solver in SNES
