Options for the SPSA optimizer.
Fields§
§max_iter: usizeMaximum number of iterations.
tol: f64Convergence tolerance on ‖step‖.
alpha: f64Exponent α in aₖ = a / (A + k)^α.
gamma: f64Exponent γ in cₖ = c / k^γ.
a: f64Scale a.
big_a: f64Stability constant A (typically ≈ 0.1 * max_iter).
c: f64Finite-difference constant c.
