#include "petsctao.h" PetscErrorCode TaoMonitor(Tao tao, PetscInt its, PetscReal f, PetscReal res, PetscReal cnorm, PetscReal steplength)
tao | - the Tao context | |
its | - the current iterate number (>=0) | |
f | - the current objective function value | |
res | - the gradient norm, square root of the duality gap, or other measure indicating distince from optimality. This measure will be recorded and used for some termination tests. | |
cnorm | - the infeasibility of the current solution with regard to the constraints. | |
steplength | - multiple of the step direction added to the previous iterate. |
