Sets constraint tolerance parameters used in TaoSolve() convergence tests

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoSetConstraintTolerances(Tao tao, PetscReal catol, PetscReal crtol)

Logically Collective

Input Parameters#

  • tao - the Tao context

  • catol - absolute constraint tolerance, constraint norm must be less than catol for used for gatol convergence criteria

  • crtol - relative constraint tolerance, constraint norm must be less than crtol for used for gatol, gttol convergence criteria

Options Database Keys#

  • -tao_catol - Sets catol

  • -tao_crtol - Sets crtol

Notes#

Use PETSC_DEFAULT to leave any tolerance unchanged.
