TaoTermIsObjectiveDefined#

Whether a standalone objective operation is defined for this TaoTerm

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoTermIsObjectiveDefined(TaoTerm term, PetscBool *is_defined)

Not collective

Input Parameter#

Output Parameter#

  • is_defined - whether the objective is defined

Note#

This function strictly checks whether a dedicated objective operation is defined. It does not check whether the objective could be computed via other operations (e.g., an objective-and-gradient callback). TaoTermComputeObjective() may still succeed even if this function returns PETSC_FALSE, by falling back to TaoTermComputeObjectiveAndGradient().
