some optimizers are based on gradient/jacobian only and cannot

- iteration counter, which is checked against a max allowance
to prevent infinite loops if no convergence is reached
- objective function evaluations, for user information only
- objective function gradient/jacobian if the function is
differentiable, for user information only
