1Blurb:: 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. 11 12Topics:: 13Examples:: 14Theory:: 15Faq:: 16See_Also:: 17
