TaoSetConstraintsRoutine

Sets a function to be used to compute constraints. Tao only handles constraints under certain conditions, see TAO: Optimization Solvers for details

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoSetConstraintsRoutine(Tao tao, Vec c, PetscErrorCode (*func)(Tao, Vec, Vec, void *), void *ctx)

Logically Collective

Input Parameters

• tao - the Tao context

• c - A vector that will be used to store constraint evaluation

• func - the bounds computation routine

• ctx - [optional] user-defined context for private data for the constraints computation (may be NULL)

Calling sequence of func

PetscErrorCode func(Tao tao, Vec x, Vec c, void *ctx);

• tao - the Tao solver

• x - point to evaluate constraints

• c - vector constraints evaluated at x

• ctx - the (optional) user-defined function context
