}Expand description
Options for the Kiefer-Wolfowitz algorithm.
Fields§
§max_iter: usizeMaximum iterations.
tol: f64Convergence tolerance (step norm).
alpha: f64Exponent α in aₖ = a / kᵅ. Must satisfy α ∈ (1/2, 1].
gamma: f64Exponent γ in cₖ = c / kᵞ. Must satisfy γ ∈ (0, 1/6] for unbiased gradients.
a: f64Scale constant a.
c: f64Scale constant c (initial finite-difference width).
