TaoSetConvergenceTest

Sets the function that is to be used to test for convergence of the 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

• tao - the Tao object

• ctx - [optional] convergence context

Note

The new convergence testing routine should call TaoSetConvergedReason().
