2Stopping critiera based on L2 norm of gradient
3Description::
4The \c gradient_tolerance control defines the
5threshold value on the L2 norm of the objective function gradient
6(for unconstrained minimum or no active constraints) or the
7Lagrangian gradient (for constrained minimum) that
8indicates convergence to a stationary point.
9The \c gradient_tolerance control is currently defined
10only for the OPT++ and ROL libraries.
