WebMay 4, 2024 · The gradient (i.e., first derivative) of the objective function is required for all Poblano optimizers. The optimizers converge to a stationary point where the gradient is approximately zero. A line search satisfying the strong Wolfe conditions is used to guarantee global convergence of the Poblano optimizers.
