Expand description

A summary of a successful optimization run.

Note that for non-convex functions, convergence to a local minimum is not guaranteed.

Fields§

§final_point: Array1<f64>

The point at which the minimum value was found.

§final_value: f64

The minimum value of the objective function.

§final_gradient_norm: f64

The norm of the gradient at the final point.

§iterations: usize

The total number of iterations performed.

§func_evals: usize

The total number of times the objective function was evaluated.

§grad_evals: usize

The total number of times the gradient was evaluated.
