#include "tao_solver.h" int TaoSetFromOptions(TAO_SOLVER solver)Collective on TAO_SOLVER
-tao_stol | - convergence tolerance in terms of the norm of the change in the solution between steps | |
-tao_fatol <fatol> | - absolute tolerance of residual norm | |
-tao_frtol <frtol> | - relative decrease in tolerance norm from initial | |
-tao_max_its <max_its> | - maximum number of iterations | |
-tao_max_funcs <max_funcs> | - maximum number of function evaluations | |
-tao_trtol <trtol> | - trust region tolerance | |
-tao_trust0 <radius> | - initial trust region radius | |
-tao_no_convergence_test | - skip convergence test in minimization solver; hence iterations will continue until max_it or some other criterion is reached. Saves expense of convergence test | |
-tao_monitor | - prints residual norm at each iteration | |
-tao_vecmonitor | - plots solution at each iteration | |
-tao_vecmonitor_update | - plots update to solution at each iteration | |
-tao_xmonitor | - plots residual norm at each iteration | |
-tao_fd | - use finite differences to compute Hessian; very slow, only for testing | |
-tao_mf_ksp_monitor | - if using matrix-free multiply then print h at each KSP iteration |
