Struct NelderMead 

pub struct NelderMead {
    pub par: Vec<f64>,
    pub value: f64,
    pub fncount: usize,
    pub fail: i32,
}

Result of nelder_mead, mirroring the parts of R’s optim return value that callers need.

Fields

par: Vec<f64>

Best parameter vector found (R’s $par).

value: f64

Objective value at par (R’s $value).

fncount: usize

Number of objective evaluations (R’s $counts[1]).

fail: i32

Convergence flag (R’s $convergence): 0 = converged, 1 = maxit reached, 10 = simplex degenerated during shrink, 2 = objective was non-finite at the starting point.
