Expand description

Configuration for the Poisson optimizer.

Fields§

§max_iter: usize

Maximum number of iterations.

§fd_step: f64

Step size for finite-difference gradient.

§step_size: f64

Initial step size for line search.

§tol_param: f64

Convergence tolerance used for both parameter displacement (L2 norm of step) and gradient-norm convergence checks in poisson_fit.

§armijo_c: f64

Armijo line search parameter (sufficient decrease).

§backtrack: f64

Line search backtracking factor.

§gauss_newton_lambda: f64

Relative diagonal damping for analytical Gauss-Newton / Fisher steps.

§lbfgs_history: usize

History size for the finite-difference L-BFGS fallback.

§compute_covariance: bool

Whether to compute the Fisher covariance matrix (and uncertainties) after convergence. Set to false for per-pixel spatial mapping when only densities are needed, avoiding extra model evaluations.
