Expand description

Configuration for the trust-region solver.

Fields§

§initial_radius: F

Initial trust-region radius (default: 1.0).

§max_radius: F

Maximum trust-region radius (default: 100.0).

§eta: F

Acceptance threshold for the ratio of actual to predicted reduction (default: 0.1).

§max_cg_iter: usize

Maximum CG iterations per trust-region subproblem (default: 2 * dim). If 0, defaults to 2 * dim.

§convergence: ConvergenceParams<F>

Convergence parameters.
