TaoSolve#

Solves an optimization problem min F(x) s.t. l <= x <= u

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoSolve(Tao tao)

Collective

Input Parameter#

  • tao - the Tao context

Notes#

The user must set up the Tao object with calls to TaoSetSolution(), TaoSetObjective(), TaoSetGradient(), and (if using 2nd order method) TaoSetHessian().

You should call TaoGetConvergedReason() or run with -tao_converged_reason to determine if the optimization algorithm actually succeeded or why it failed.
