TaoSetConvergenceTest#

Sets the function that is to be used to test for convergence o fthe iterative minimization solution. The new convergence testing routine will replace Tao’s default convergence test.

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoSetConvergenceTest(Tao tao, PetscErrorCode (*conv)(Tao, void *), void *ctx)

Logically Collective

Input Parameters#

  • tao - the Tao object

  • conv - the routine to test for convergence

  • ctx - [optional] context for private data for the convergence routine (may be NULL)

Calling sequence of conv#

PetscErrorCode conv(Tao tao, void *ctx)

  • tao - the Tao object

  • ctx - [optional] convergence context

Note#

The new convergence testing routine should call TaoSetConvergedReason().
