Configuration for Riemannian Gradient Descent.

Fields

max_iters: usize

Maximum number of iterations.

grad_tol: Real

Stop when ||grad f(x)|| < grad_tol.

init_step: Real

Initial step size for Armijo backtracking.

armijo_c: Real

Armijo sufficient decrease constant (typically 1e-4 to 0.5).

armijo_beta: Real

Backtracking factor (< 1, typically 0.5).

max_ls_iters: usize

Maximum number of backtracking steps per iteration.
